Germanium Glass Window Thermal Imaging Camera Window Germanium Lens Monocrystalline Germanium Filter Germanium Lens Coating

Germanium glass has good light transmittance in 2-16um, and its chemical properties are relatively stable. It is not easy to react with metal oxides, acidic substances such as air and water. Infrared thermometer and thermal imager need medium and far infrared filters. Thermometer and thermal imager generally work in 2-13um band, while germanium glass has good transmittance in mid and far infrared. Ordinary optical glass transmittance in these bands is very low, so it is difficult to achieve. Adding optical thin film to germanium glass can greatly increase its transmittance and reduce the reflectivity of germanium glass surface. Germanium glass is impermeable in the visible band.            In some thermal imagery, we can also use silicon crystal instead of germanium glass. The working band of silicon crystal is not as far as germanium glass.            Silicon (Si) single crystal is a kind of chemical inert material with high hardness and insolubility in water. It has good light transmittance in 1-7 micron band.            At the same time, it also has good transmittance performance in the far infrared band of 300-300 um, which is unique to other light-infrared materials.            Points. Silicon (Si) single crystals are commonly used as substrates for 3-5 micron mid-wave infrared optical windows and optical filters.            Low density is also a common material for making laser mirrors or infrared temperature measurement and infrared optical lenses.            We can make all kinds of silicon flat-convex lenses, silicon double-convex lenses, silicon flat-concave lenses and silicon double-concave lenses for you.            Coating: Coating according to customer's requirements            technical requirement            Tolerance range            Size range            1-400 mm            Dimensional tolerance            + 0/-0.05mm            Angular tolerance            +2"-+5"            surface quality            40/20            Surface Accuracy            Lambda/10 per@633 NM            Inverted side            0.1-0.5mm            Material Science            Silicon SI            Coating            Coating: Coating according to customer's requirements            The main product fields of Pingzhi Optics in Shenzhen include: filter for optical fiber communication, narrow band filter, band pass filter, long and short wave filter, high precision mirror, filter for biometric identification, infrared filter, filter for medical instrument, filter for enzymograph and optical lens, optical prism, spherical surface.
