Metalized sapphire windows are created by applying thin layers of chrome, nickel and gold around the edge of a sapphire window. This metalized edge creates a surface that can be soldered or bonded directly into your opto-mechanical assembly allowing you to create a hermetic seal. Hermetically sealed optics is used in a variety of applications ranging from infrared imaging systems to medical devices.

Photonchina s windows are used to isolate different physical environments while allowing light to pass. When selecting windows you should consider materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain environments. We offer a wide range of different materials and different degree of precision windows. Special materials are available upon requirement. A broad range of single layer or multilayer antireflective coatings on optical windows are available. N-BK7 Optical Windows N-BK7,or H-K9L Chinese equivalent, is an excellent optical glass material for most visible and near infrared applications. It is the most common borosilicate crown optical glass, and it provides great performance at a good value. Its high homogeneity, low bubble and inclusion content, and straightforward manufacturability make it a good choice for transmissive optics. UV Fused Silica Optical Windows UV Fused Silica Windows feature low distortion, excellent parallelism, low bulk scattering and fine surface quality. This makes them perfectly suited for a wide variety of demanding applications, including multiphoton imaging systems and intracavity laser applications. Calcium Fluoride Optical Windows Calcium Fluoride optical windows are transparent from 180 nm to 8 �±�²�³�´�µm, making them ideal for applications such as spectroscopy or fluorescence imaging in the UV, visible, and IR wavelengths. Sapphire Optical Windows Uncoated Sapphire windows are ideal for harsh conditions, including environments subject to high temperatures, high pressures, strong vacuum, or corrosive atmospheres. Sapphire has high compressive strength and is resistant to attack from strong acid. Wedged Windows Photonchina high-energy laser wedge windows are specially designed to eliminate losses in vacuum cell applications and can be used as vacuum windows, convection barriers, or interferometer compensator plates. Brewster Windows When oriented at Brewster's angle (55.57�¬), s-polarized light is partially reflected, p-polarized light is transmitted without loss. When placed inside a laser cavity Brewster windows cause p-polarized light to have higher effective gain, resulting in the laser's final output being strongly p-polarized. Photonchina Brewster windows are made of UV grade fused silica with laser grade surface quality and parallelism, making them ideal polarizers for use inside a laser cavity.
