ISP Optics Infrared (IR) Dichroic Beamsplitters

ISP Optics Infrared (IR) Dichroic Beamsplitters are used to separate visible light from infrared light, working deeper in the infrared than conventional hot and cold mirrors. The platinum dichroic beamsplitters reflect visible light while transmitting light between 3 – 12µm and have an Anti-Reflection (AR) coating on the back surface to increase throughput. The gold dichroic beamsplitters transmit visible light while reflecting infrared light between 3 – 12µm and can be used with an AOI from 0 to 45°. ISP Optics Infrared (IR) Dichroic Beamsplitters are ideal for combining guide lasers with mid-IR laser sources, such as QCL lasers, for applications including gas detection, mid-infrared photothermal microscopy, and infrared spectroscopy.
