Evaporated Metal Films (EMF)
Cold Mirrors with Reflection Region 420-630 nm or 325-475 nm
Cold Mirrors for HUDs (Head-Up Displays)
EMF’s high transmission cold mirrors are an excellent choice for preventing undesirable ultraviolet and visible light from damaging or altering the spectral characteristics. They reflect visible light while allowing infrared light to transmit. EMF offers two designs for use at either 0° or 45° AoI (Angle of Incidence.) These may also satisfy your requirements of a dichroic beamsplitter.
These specialized dielectric mirrors are produced using borosilicate or float glass as the substrate. Please contact EMF if you require different substrate materials for extremely high-temperature applications, or need them in a custom shapes and sizes.
