1 Product Details


      Optical protective window sapphire crystal glass window


         Sapphire is used for windows in 250-5000nm wavelength range. It is recognized as a highly important optical material because optical grade sapphire combines high transmission with outstanding mechanical-strength properties at high temperatures. Sapphire windows can be made thinner than alternative crystals thanks to its structural integrity and can operate up to 2030⁰C.

      Sapphire windows are widely used as protective windows or viewports. Sapphire windows are ideal for applications where high pressure, vacuum, or corrosive atmospheres are a consideration.

       

Material: K9, BK7, FS, UVFS, CaF₂, ZnSe

Diameter:3mm-200mm±0.05mm

Center Thickness Tolerance:±0.05mm

Lens Alignment Error:≤3min

Surface Accuracy:λ/ 10 @

Surface Quality:40/20. 60/40. 80/60

Effective Caliber: 90%



       Example with BK7 material:These N-BK7 Meniscus lens are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
