850nm beam splitter

850nm beam splitter is also called beam splitter. Optical coating manufacturers call this product beam splitter; All dielectric beam splitter (made of Ta2O5 and SiO2 materials by cross vacuum coating). The other is the metal plus medium spectroscope, also known as the attenuation plate, because it only considers passing through the light transmission ratio column and does not take the reflected light as the reference focus. Generally, chromium or nickel chromium alloy is added with plating medium or diamond film to enhance its firmness and not be affected by environmental damage. The higher the reflectivity of the spectroscopic film, the more difficult it is to produce or the spectroscopic value tends to be the smallest, and the more difficult it is to plating.
