The cold mirrors of our SHD series provide a very high reflection for visible light sources and lasers. Since they have a good transmission for infrared wavelengths up to 2500 nm, they are excellently suited to filter cool light out of a beam path. The SHD mirrors offer a very strong reflectivity for visible light, while they let pass hot infrared light (heat) at the same time.
The coating is designed for a reflection angle of incidence of 45° and lets pass the infrared at 0° in reference to the incoming light beam. The optic offers a very good surface quality and is suitable for various optical applications. In addition to the main use as a cold mirror, the SHD can also couple visible lasers into infrared light- or laser beams. In many cases, it is possible to use the cold mirrors as efficient, cost-effective laser optics.
The dielectric coating construction of the SHD mirrors ensures permanent resistance to heat and moisture. As mirror substrate for the SHD we use quality borosilicate glass, which enables it to be used even at high operating temperatures.
Our company also produces cold mirrors according to customer's specifications. On a batch basis, the layer systems can be modified in relation to the reflection range, angle of incidence, the cut-on and cut-off point, as well as to the center wavelength according to customer requirements.
