Our standard line of high transmission Cold Mirrors are a great choice for preventing undesirable ultraviolet and visible light from damaging or altering the spectral characteristics beyond that position in a light path by reflecting visible light while allowing infrared light to transmit. Two designs are offered for use at either 0° or 45° angle of incidence. These specialized dielectric mirrors are produced on Borosilicate/Float glass. Cold Mirrors may also satisfy your requirements of a dichroic beamsplitter. If other substrate materials are of interest to you, for very high temperature applications for instance, please contact us. Custom sizes are easy to process as well.
