  • Optical Windows Wedge Brewster Angle Fused Silica Caf2 Or Sapphire Material - China

    price: 6.00 Dollar US$

    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 ±²³´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.

    • Business Description: Quartz Waveplate

      Photonchina is a leading manufacturer of quartz waveplate products in the world.

      Our complete quartz waveplate range includes true zero order, zero order, multiple order, with the retardation of half, quarter or octadic wave.

      Special types like achromatic and dual wavelength waveplate, either in circular or quadratic shape, are all available.

      Thickness of true zero order waveplate T=0.027mm, is the latest accuracy level reached, thanks to our special production technique and skilled technicians.

      Crystal Polarizer

      Giant company and small start-up have all chosen our polarizer products for their applications in laser, telecommunication,surveyi ng or others.

      Glan laser polarizer, Glan taylor polarizer, Wollaston polarizer, Glan thomson polarizer etc, made of BBO, YVO4, Calcite crystal, are produced by the team with more than ten years of experience.

      High quality crystal materials and excellent optical coating performance have contributed to customer's approval worldwide.

      Photonchina offers polarizer with or without mount.


      You may find various types of lenses from Spherical lenses, Cylindrical lenses to Acylindrical lenses here, produced by materials of BK7, Fused Silica as well as Calcium Fluoride, Sapphire, Silicon and Germanium etc.

      With the rich experience in manufacturing lenses and the help of high-end of optical coating machine, Photonchina has supplied lenses with mass quantity or custom small number to customers worldwide for more than a decade.

      Standard diameters have been 0.5mm-160mm with various radii and types upon customer request.

      Micro lens has now reached 0.5mm diameter, one of the smallest lens ever produced.


      Photonc hina supplies an array of high precision prisms.

      These prism products have been manufactured with stringent inspection for angle, surface quality, flatness, transmitted wavefront, dimension, clear aperture and optical coating performance.

      Our current capabilities include Roof prism,Right angle prism, Penta prism, Rhomboid prism, Dove prism,Wedge prism, Anarmophic prism,Pellin-Broca prism etc.
