Optical Breadboard 12 x 12 in., 1/2 in. Thick, 1/4-20 Inch Tapped Holes, Vacuum Compatible, AluminumThese vacuum compatible aluminum optical breadboards are the perfect low-cost solution when building optical subassemblies that require a vacuum environment. They are 1/4"-20 tapped on a 1" standard optical table breadboard pattern (the first row of holes are 0.5 inches from the edge). They have five counterbored holes, one on each corner inset 1" from the edge and one in the center, which are used with 1/4" socket head cap screws to provide a smooth top surface when mounting the breadboard to a table or adding pedestals as feet. The flatness is specified as 0.006" over 1 ft2. These breadboards can be used inside a vacuum chamber system due to the lack of an anodized coating, down to 10-6 Torr. Ultra-High Vacuum ranges could be reached with additional post-process cleaning by the user. Also, the mounting holes are tapped through the entire thickness of the plate.

304 Stainless Steel Weldable Vacuum Standoffs for Optical BreadboardsThese Ideal Spectroscopy precision-machined 304 stainless steel standoffs are designed to provide a reliable and repeatable mounting solution for installing vacuum-rated optical breadboards inside vacuum chambers. Each standoff features a tapped 1/4"-20 thread, allowing secure attachment of the optical breadboard using standard socket head cap screws (SHCS) through the breadboard mounting holes. The standoffs are intended to be temporarily positioned using our vented 1/4"-20 fasteners, enabling accurate alignment prior to final installation. Installation Process The recommended installation method ensures precise placement: Attach standoffs to the optical breadboard using vented fasteners Position the assembly insdie the vacuum chamber Tack weld each standoff to the chamber wall in the desired location Remove the breadboard Complete the final TIG or laser weld around each standoff as required This approach guarantees that all mounting points are correctly aligned with the breadboard. Vacuum-Compatible Design Integrated vent ports prevent virtual leaks by allowing trapped gases to escape during pump-down Fully compatible with high and ultra-high vacuum environments Designed to maintain system cleanliness and performance Materials Standard: Corrosion-resistant 304 stainless steel Optional: Aluminum versions available upon request (custom order) These standoffs provide a simple, accurate, and vacuum-friendly solution for permanently mounting optical breadboards within your chamber.
