The window is used to separate the environment on both sides, such as separating the inside and the outside of the instrument, so that the inside and the outside of the instrument are isolated from each other, thereby protecting the internal components. The window is a basic optical element, an optical flat plate, which does not change the optical magnification, but only affects the optical path in the optical path. The important parameters of the window: light transmittance, surface accuracy, thickness, parallelism, substrate material, and other properties. You can choose the window with suitable parameters according to the specific application. Huasen Optoelectronics can provide high-precision windows of various materials, such as zinc selenide windows, germanium windows, silicon windows, barium fluoride windows, and calcium fluoride windows used in the infrared spectrum; used in ultraviolet Fused silica windows and sapphire windows in the spectral band; K9 windows in the visible spectral band, etc. We can customize optical windows according to specific needs.
λ/4, λ/10 visible light window
The plane window is a parallel plane plate, which is usually used as a protective film for electronic sensors or external environment detectors. Huasen Optoelectronics provides flat windows with a variety of substrates without coating and with an antireflection coating. Antireflection coating options include UV, VIS, NIR, and SWIR. Barium fluoride (BaF2), calcium fluoride (CaF2), zinc sulfide (ZnS), zinc selenide (ZnSe) or silicon (Si) germanium (Ge) are suitable for infrared applications, while fused silica and sapphire are suitable for ultraviolet applications.
UV Fused Silica Standard Precision Flat Window
The plane window is a parallel plane plate, which is usually used as a protective film for electronic sensors or external environment detectors. Huasen Optoelectronics provides flat windows with a variety of substrates without coating and with an antireflection coating. Antireflection coating options include UV, VIS, NIR, and SWIR. Barium fluoride (BaF2), calcium fluoride (CaF5), zinc sulfide (ZnS), zinc selenide (ZnSe) or silicon (Si) germanium (Ge) are suitable for infrared applications, while fused silica and sapphire are suitable for ultraviolet applications.
K9 high precision double-sided optical flat crystal
Flat crystal can be used as a standard plane to detect and identify the flatness error and lapping performance of the high-gloss and clean surface of other components. It has high-precision flatness and is generally used alone. There are two types of surface types: λ/10 and λ/20. Huasen Optoelectronics provides a variety of uncoated double-sided and single-sided optical flat crystals based on K10 optical glass and UV fused silica. Fused silica is suitable for UV applications.
K9 ball cover
The dome window is a protective window in the shape of a hemispherical shell, which is often used for applications with a large-angle range of incident light, such as detectors, optical sensors, and other applications. Huasen Optoelectronics provides various uncoated wedge-shaped windows based on K10 optical glass and UV fused silica. Fused silica is suitable for UV applications.
K9 high precision wedge window
The two planes of the wedge-shaped window have an included angle of 31 arc minutes. Two non-parallel planes can avoid the interference effect (Etalon effect) caused by the light reflected from the front and rear surfaces of the high parallelism window, and also avoid the optical interference feedback of the laser cavity, which leads to poor laser output stability and mode jumps. Wait. Huasen Optoelectronics provides non-coated, anti-reflection coated wedge-shaped windows. Antireflection coating options include UV, VIS, NIR, and SWIR. Fused silica is suitable for UV applications.
Brewster Window Film
Use Brewster window to obtain linearly polarized light. When light is incident at a specific angle of incidence (called the Brewster angle of the material), the S polarization component of the incident light is partially reflected, while the P component is nearly completely transmitted. Through multi-layer coating, the S component is continuously reflected, and finally, only the P component is transmitted.
