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