And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.
The window slice is used to separate the environment on both sides, such as separating the interior and exterior of the instrument, so as to isolate the interior and exterior of the instrument from each other, so as to protect the internal devices. Window slice is a basic optical element and an optical flat plate. It will not change the optical magnification and only affect the optical path in the optical path. Important parameters of window slice: transmittance, surface accuracy, thickness, parallelism, base material and other attributes. Window slice suitable for parameters can be selected according to specific application.
Borisun optics can provide high-precision window slices of various materials, such as zinc selenide window slice, germanium window slice, silicon window slice, barium fluoride window slice and calcium fluoride window slice applied in infrared spectrum band; Fused quartz window and sapphire window used in ultraviolet spectrum; K9 window film applied in visible spectrum band, etc. We have a large stock of standard products in stock. At the same time, we can also customize optical windows according to specific needs.

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.
