All products

AR coated Colour glass window

Color glass change the spectral properties of optical radiation. They therefore allow scientific experiments and industrial applications where that change is necessary. You can combine color glass filters together to change the band pass or to increase the attenuation.

AR Coated Sapphire Windows

Sapphire window retains its high strength at high temperatures, has good thermal properties and excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to HF below 300 °C . These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.

AR Coated BK7 Windows

BK7 window is the most common type of window. It has good performance over visible and near infrared wavelength region. At the same time,BK7 window is ideal for applications require minimal transmitted beam deviation. It is suitable for AR coating .

UV Fused Silica High-Precision window

Fused silica window, with low thermal expansion, providing stability and resistance to thermal shock over large temperature excursions, wide thermal operating range and high laser damage threshold, is a better choice for transmission from UV to IR.

IR Windows Calcium Fluoride CaF2 Windows

Calcium Fluoride windows and lenses for UV and IR spectrum. Custom made CaF2 windows, CaF2 lenses and wedges according customer's specifications. CaF2 windows up to 220mm diameter; CaF2 wedges, prisms and CaF2 mirrors; Excimer CaF2 optics, Raman grade CaF2 optics and etc.

Magnesium Fluoride (MgF2) Windows

Magnesium Fluoride Windows applicable for wide range spectrum, transmits well into the VUV region at the hydroge Lymanalpha line and beyond and it is particularly useful for Excimer laser application. It is resistant to mechanical and thermal shock, to radiation, and is chemically stable.

IR Windows Germanium Windows

Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 um wavelength band.

Silicon Windows

Silicon is used as an optical window primarily in the 3 to 5 micron band and as a subsrate for production of optical filters and windows.

IR Windows Zinc Selenide(ZnSe) Windows

ZnSe is used widely for IR components, windows and lenses, and applied for Thermal Imaging, FLIR, Medical systems and Co2 Laser
