Cold mirrors of our SHD series provide excellent optical reflectivity for visible light sources. Since the mirrors also offer high optical transmission for infrared wavelengths up to 2500 nm, they are perfectly suited as filters for the extraction of cold light and removal of thermal energy from a beam path, while maintaining a high optical imaging quality. We designed the dichroic coating of the SHD mirrors for an angle of incidence of 45° and for best transmission of infrared radiation at 0° related to the incident light beam.
Our SHD cold mirror optics offer a high surface quality and are suitable for various optical applications. In addition to the primary application as a cold mirror, the dichroic optics can also be used to merge visible lasers with infrared laser beams. Besides that, in many cases, it is possible to use our standard SHD as an efficient and cost-effective laser mirror for visible wavelengths and unpolarized laser systems.
The dielectric coating construction of the SHD optics ensures permanent resistance to thermal load and moisture. The glass substrate we use is a premium grade borosilicate glass which enables the SHD to operate at high temperatures and that offers an excellent optical performance.
Our company also has the capabilities to produce cold mirrors according to customer's specifications. On a batch basis, we can modify the layer systems of the optics concerning the reflection-range, angle of incidence, the cut-on, and cut-off wavelengths, damage threshold, as well as to the spectral operating range.
