Our SHD cold mirrors provide excellent optical reflection for visible wavelengths while transmitting more than 90% of the infrared light up to 2500 nm on average. They are ideal for extracting the cold visible light from the beam path while removing most of the thermal energy. We designed the dichroic SHD mirrors to reflect at an angle of 45° and transmit the infrared radiation at 0° related to the incident light beam.
SHD cold mirrors feature high imaging quality. Hence, in addition to the primary use as a cold mirror, the SHD can also merge visible with infrared light or laser beams. They also work as efficient and cost-effective laser mirrors for visible light. The dielectric construction ensures permanent resistance to thermal load and moisture. Premium-grade borosilicate glass substrates enable the SHD cold mirrors to work at increased operating temperatures.
We also produce customized cold mirror optics. We can modify the layer system concerning reflection wavelength, angle of incidence, cut-on, cut-off wavelengths, damage threshold, and spectral operating range on a batch basis. If you need support with your customized cold mirror design, please use our inquiry form or send an email with your detailed requirements.
