Optical Windows
We can provide optical glass Square Windows
PARAMETER:
Optical Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass,it also can be a protection of original when it's in two physical environments.And there is almost no effect on visible light,to coat on the surface of windows could increase the transmittance,the commonly used coatings are antireflection coating (AR) and scratch-resistant coating(AS).Windows with coating can enhance the light penetration strength,and own function of waterproof ,dustproof,and scratch-proof.
They are mainly used in mobile phone screen and lens protection,digital camera, digital video recorders, industrial optical windows, touch screen products, GPS products, digital electronic products windows, car rearview mirror, computer screen, laptop screen, watch surface and so on.
BRD Optical Provide Custom Round Windows. Special size and materials are also available upon request. In addition, we provide a variety of single layer or multiplayer anti-reflecting coating on optical windows.

BK7 B270 Optical Glass Window An Optical Window is an optically flat. These regular windows are applied to isolate different physical environments while allowing light pass. When selecting windows,please consider materials, transmission, scattering, parallelism and resistance to certain environment. It can be widely used on laser technology, IR detector and imaging technology etc. Worldhawk offers standard and high precision optical glass windows in round ,rectangular, wedge windows and custom shape and size with different optical glasses,Fused Silica, Sapphire, ZnSe, Zns and IR crystal. The high precision parallelism of 10 arc seconds, surface quality of 10/5 and flatness of �»/20. Single layer or multi-layer anti-reflection coatings are available.
According to custom design to manufacture infrared windows, uv fused silica windows, caf2 windows, znse windows, si windows, etc. Material: flint glass, uv fused silica, infrared fuses silica, caf2, ge, znse, si, etc. Diameter: 4mm-- 100mm Parallelism:

Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. Specifications Diameterï 1mm to 1000mm. Diameter Tol.+/-0.02mm Material Bk7 sapphire fused silica,ZnS2,CaF2,Si,Ge. Surface Quality10-5 standard Flatness 1/10 lambda Parallisa
The high-precision window is made of BK7 optical glass and UV fused quartz, the fused silica quartz window plate is suitable for high power laser that needs good thermal stability, and the window made of N-BK7 material is cheaper, which is suitable for laser applications that pay more attention to cost.Both fused quartz and N-BK7 laser window plates have precision grades of 1/10 lambda surface flatness and 10-5, 20-10 surface quality to ensure minimal interference to the transmitted beam.Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. we can offer 24 inch zygo flatness reports, full CA 600mm windows.

Calcium fluoride has a high transmittance from ultraviolet to mid-infrared (250nm~7um), so it is widely used in the manufacture of prisms, Windows and lenses, In some applications with a wide spectrum range, it can be used directly without coating film, Especially, it has low absorption and high laser threshold, so it is suitable for application in excimer laser optical system, we are manufacture CaF2 optics, the size range from 3mm to 280mmSurface Quality: 40-20, Flatness: 1/10 lambda@633nm(Lens diameter and thickness need to be right proportion)
