Large size Barium fluoride
Barium fluoride crystals larger than 120 mm in size can be monocrystalline or polycrystalline. We can provide 50 pieces of polycrystalline barium fluoride material of D140*30mm per month, the maximum size of polycrystal can reach 320mm; 100 pieces of monocrystalline material of D100*20mm per month, the maximum size of monocrystal is D130mm.
Silicon single crystal is usually used as the substrate of 3-5μm mid-wave infrared optical window and optical filter. It is a common material for making laser mirror, infrared temperature measurement and infrared optical lens because of its good thermal conductivity and low density.
The complex surface profile of an asphere can significantly reduce or even eliminate spherical aberrations comparing to spherical lenses.
Hence, asphericals have been increasingly more widely explored and adopted during the optical design stage.
Aspheres can replace a complex multi-element spherical system to achieve a lighter and more compact optical system.
The resulting design has higher transmittance and in most cases, costs less than the multi-lens spherical design, especially at production volumes.
Barium Fluoride(BaF2) Dome
Barium fluoride (BaF2) crystals belong to the cubic crystal system, good moisture resistance, melting point of 1280°C, high operating temperature, refractive index in a wide range of wavelengths does not change much, wide range of light transmission, in the 0.2μm to 10μm wavelength range can reach more than 90%, but the mechanical strength is poor Mohs hardness of 87. In the aircraft guidance head or EO/IR platform, can be made into a dome The spheres can be made into spheres for aircraft guidance heads or EO/IR platforms.
Pyroelectric Infrared Sensor SO1-V A2
The SO1-V A2 flame detector is based on the pyroelectric effect of LiTaO3 single crystal, combined with ultra-low noise JFET and silicon substrate narrow band filter. The detector have good anti-interference ability and high sensitivity at the same time.This type of detector can be used in small space flame detection.
Pyroelectric Infrared Sensor SO1-V A1
The SO1-V A1 flame detector is based on the pyroelectric effect of LiTaO3 single crystal, combined with ultra-low noise JFET and silicon substrate narrow band filter. The detector have good anti-interference ability and high sensitivity at the same time.This type of detector can be used in long distance flame detection.
