Laser Viewport, Zinc Selenide, Zero Length 4.5 inch Conflat Flange (CF-4.5 in.), UHV Grade, ZnSe, 1.9" Viewport Diameter, 304 SS
Out of Stock


For many MWIR (Mid-Wave Infrared) to IR applications requiring broad range transmission of infrared (IR) light, these zero-length viewports offer low absorptivity of wavelengths up to 16 microns. Importantly, these ZnSe viewports are highly resistant to thermal shocks rendering them ideal for high power applications using CO2 laser systems. Additionally, these viewports allow some transmission of visible light, making fine tuning of optical aligments and interior components using combination CO2-HeNe lasers simple and easy.Unless treated with strong acids, ZnSe is chemically stable and non-hygroscopic and safe to use in many industrial, field, and laboratory applications. This substrate scratches easily and should be handled with care. When handling optics, always wear soft, non-absorbent, lint-free gloves. Never use ultrasonic cleaning methods to treat ZnZe viewports. Please observe the following procedure when cleaning these viewports:

Viewport, Fused Silica, Zero Length 2.75 inch Conflat Flange (CF-2.75 in.), DUV Grade, AR Coating, 1.4" Viewport Diameter, 304 SS
Out of Stock


DUV-grade fused silica for applications requiring transmission deep into the ultraviolet spectrum in addition to a low index of refraction for a given wavelength, excellent homogeneity, and low coefficient of thermal expansion. Unlike common glasses (Pyrex, borosilicate, soda-lime, etc.) fused silica contains no Na2O, CaO, or B2O3 and is composed exclusively of high-purity silica (SiO2) in amorphous (non-crystalline) form. It has a much higher working and melting temperature than other common optical glasses, and has exceptional optical, thermal, and mechanical properties. Fused silica is highly resistance to thermal shock, and is an excellent material for applications requiring the utmost in dimensional stability over a large temperature range and steep thermo-temporal gradients. For comparison, INVAR (a nickel-iron alloy), which has the lowest thermal expansion among all metals and alloys near room temperature, has a mean coefficient of thermal expansion that is more than twice that of fused silica over a temperature range of 20C to 100C.

Viewport, Magnesium Fluoride, Zero Length 2.75 inch Conflat Flange (CF-2.75 in.), AR Coating, 0.9" Viewport Diameter, 304 SS
Out of Stock


Magnesium fluoride transmits well between the deep ultraviolet and the mid-infrared regions and is used mostly for UV optics and Excimer laser applications. These MgF2 windows are usable in the UVA, UVB, visible and IR ranges, with approximately 94% transmission from 200 - 1000 nm, and approximately 95% transmission from 1 - 6 m. Magnesium fluoride is a tough material, polishes well, and can be worked to a high standard. It is slightly birefringent and usually manufactured into viewport windows where the optic axis cut perpendicular to the window face. MgF2 is also naturally birefringent, making it an ideal material for use in retardation plates and polarizing elements, particularly in the wavelength range from 0.13-0.30 m.
