Ideal Vacuum Cube 9 x 9 in. Gate Valve Adapter Plate Kit ISO-F 100. This is an ISO-F 100 gate valve adapter plate kit for the 9 x 9 Ideal Vacuum Cube. This adapter allows the compact connection of an ISO-F 100 gate valve (with tapped mounting holes) to an Ideal Vacuum Cube™, without additional plumbing or fittings. The adapter consists of two plates. One plate has our patented Taper-Seal™ O-ring seal and is mounted to the Cube frame. The other plate is mounted to the gate valve’s threaded flange. An ISO 100 centering ring with O-ring is sandwiched between the two plates which are then screwed together to make the seal. This adapter kit can be used to isolate a turbomolecular pump from the chamber. It creates the shortest possible pumping path for maximum high vacuum performance. Another use for the gate valve adapter kit is to join two Cubes together in load lock applications. Two adapter kits are required, one on each side of the gate valve. When two cubes are joined with a gate valve between them, one Cube can be used as an antechamber to transfer materials from ambient atmosphere into the other which remains under vacuum. Similarly, when two Cubes of differing sizes are joined with a gate valve between them, the system can be used for explosive decompression testing. Here, the larger Cube decompresses the smaller Cube. It is best to use a pneumatic gate valve since it opens more rapidly than a manually operated one. Please download the gate valve adapter kit user manual for installation instructions.

Ideal Vacuum Cube 9 x 9 Viewing Window Plate Assembly 3/8" Tempered Glass, Uncoated for Bakeout This Ideal Vacuum Cube 9 x 9 inch vacuum chamber standard, low-iron, tempered glass viewing window plate assembly is designed to fit our 9 x 9 x 9 modular Cube chambers. The standard tempered glass window viewing plate assembly is a popular Cube option, commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is 3/8" thick, tempered, low-iron, high-clarity glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for high power laser experiments. We also offer high purity fused silica windows which are ground and polished to optical grade on both sides with a total thickness variation (TTV) of <10µm, a surface finish of S/D 40/20, and a surface roughness of Ra < 1 nm. These windows have appreciably improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include extraordinarily low refractive index variations, low birefringence values, and an ultra-low thermal expansion coefficient. Fused silica is used for transmissive optics where a high laser damage threshold is required. Fused silica is used for optics operating in the deep UV, visible, and the near infrared wavelength range. Our Cube viewing windows employ an innovative, zero metal-to-glass contact design that holds the 3/8” thick window pane to an aluminum mounting plate. This cushioned window mounting system ensures operator safety and is less prone to leakage than other viewport window configurations, even at high vacuum pressures. Ideal Vacuum Cube windows are delivered fully assembled and use Viton O-rings and Teflon spacers. Bakeout temperatures to 150 °C are permissible. The viewing window plate assembly is interchangeable with other Cube plates and can be added to an Ideal Vacuum Cube system anytime. The viewing window can be implemented as a fixed side, or a door (with our optional hinge assembly and hardware kit, P106868) on the Cube chamber. The viewing window plate assembly, like all our other Cube plates, is built with our patented Taper-Seal technology which incorporates sloped sealing features to help prevent damage to the vacuum sealing surfaces. All Ideal Vacuum Cube plates are CNC milled from a single block of lightweight 6061-T6 Aluminum Alloy. Before it ships, every viewing window plate assembly is visually inspected for window media imperfections, helium leak tested, cleaned and sealed, ensuring that it operates correctly, safely, and is ready for immediate installation upon delivery. NOTE: All viewing windows or viewports are inherently fragile, should be handled carefully, and always inspected before use. Ideal Vacuum viewing windows are designed and rated for VACUUM ONLY and can be susceptible to thermal shock if exposed to rapid temperature changes (>10° C /min). If directing a laser beam through the window, make sure the laser’s wavelength can be reasonably transmitted through the window’s material. Please download and read all the safety warnings in the IVP Cube Viewing Window Assembly Manual.

Ideal Vacuum Cube 9 x 9 Viewing Window Plate Assembly 3/8" Fused Quartz, Uncoated for Bakeout This uncoated Ideal Vacuum Cube 9 x 9 inch vacuum chamber fused quartz viewing window plate assembly is designed to fit our 9 x 9 x 9 modular Cube chambers. The fused quartz window viewing plate assembly is often selected for experiments where improved optical clarity, extended wavelength transmissivity is required beyond the visible range, and where cost is a factor. Our fused quartz windows are manufactured with the highest quality natural quartz resulting in the highest levels of purity and lowest inclusion and bubble levels. Comparable to Heraeus TSC-3, these windows have improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include low refractive index variations and low thermal expansion coefficient. Fused quartz is used for semiconductor applications such as plasma etch and deposition systems and recommended when low alkali and low aluminum content are specified. It is often used for transmissive optics in the visible and near-to-mid infrared wavelengths where a high laser damage threshold is required. Fused quartz has absorbtion bands in the 2600 to 2900 nm region, similar to fused silica but not as strong. It is unsuitable for UV work due to absorbtion in the 270 nm region. Note that fused quartz stock is limited as Ideal Vacuum is transitioning to fused silica as its premium window offering. Also note that fused quartz windows may be erroneously labeled with fused silica part numbers. You may verify your window material by checking your sales invoice. We also offer Cube window plate assemblies and replacement window panes with standard low-iron tempered glass or fused silica. Tempered glass is commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is standard low-iron float glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for laser experiments below visible or beyond near-infrared (NIR) wavelengths.

Ideal Vacuum Cube 9 x 9 Replacement Window for Viewing Plate Assembly 3/8" Tempered Glass. This is a tempered glass replacement window for the Ideal Vacuum Cube 9 x 9 Viewing Window AssembIy. Use it to replace a scratched, hazed or discolored glass window. It replaces the tempered glass viewing window pane used on our 9 x 9 x 9 Cubes. The standard tempered glass window is commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is 3/8" thick, tempered, low-iron, high-clarity glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for high power laser experiments. We also offer high purity fused silica replacement windows which are ground and polished to optical grade on both sides with a total thickness variation (TTV) of <10µm, a surface finish of S/D 40/20, and a surface roughness of Ra < 1 nm. These windows have appreciably improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include extraordinarily low refractive index variations, low birefringence values, and an ultra-low thermal expansion coefficient. Fused silica is used for transmissive optics where a high laser damage threshold is required. Fused silica is used for optics operating in the deep UV, visible, and the near infrared wavelength range. Newer versions of the viewing window assembly are field upgradeable. Please download the IVP Cube Viewing Window Assembly Manual for instructions. If you have an older viewing window plate assembly (does not have a bare aluminum window frame), we will upgrade the entire viewing window assembly at no charge to our latest version when you order a replacement window. The latest version includes thicker glass and is more leak resistant. When you purchase the new replacement window, just let us know (by phone or email) that you have an older model. We will provide an RMA and return shipping label for you to send us your old viewing window plate assembly. Once we receive the old plate assembly, we will send you a complete, fully tested, updated assembly. Old plate assemblies will not be returned.

Ideal Vacuum Cube 9 x 9 Replacement Window for Viewing Plate Assembly 3/8" Fused Quartz. This is a fused quartz replacement window for the Ideal Vacuum Cube 6x6 Viewing Window AssembIy. Use it to replace or upgrade a scratched, hazed or discolored glass window. It replaces the viewing window pane used on our 9 x 9 x 9 Cubes. Our fused quartz windows are manufactured with the highest quality natural quartz resulting in the highest levels of purity and lowest inclusion and bubble levels. Comparable to Heraeus TSC-3, these windows have improved transmittance, and a wider useful wavelength range than standard glass. Characteristics include low refractive index variations and low thermal expansion coefficient. Fused quartz is used for semiconductor applications such as plasma etch and deposition systems and recommended when low alkali and low aluminum content are specified. It is often used for transmissive optics in the visible and near-to-mid infrared wavelengths where a high laser damage threshold is required. Fused quartz has absorbtion bands in the 2600 to 2900 nm region, similar to fused silica but not as strong. It is unsuitable for UV work due to absorbtion in the 270 nm region. Note that fused quartz stock is limited as Ideal Vacuum is transitioning to fused silica as its premium window offering. Also note that fused quartz windows may be erroneously labeled with fused silica part numbers. You may verify your window material by checking your sales invoice. We also offer replacement Cube window panes with standard low-iron tempered glass or fused silica. Tempered glass is commonly used for general, direct observation of roughing or high-vacuum chamber processes and can be used to facilitate optical alignments of chamber components, observe degassing of fluids, or used to help teach in-vacuo processes by direct observation. The glass material is standard low-iron float glass. Surface quality and flatness is Q4 per ASTM 1036-06 and 1048-04. The low iron content of the glass results in it having a slight blueish tint. This economical glass is unsuitable for laser experiments below visible or beyond near-infrared (NIR) wavelengths.
