Holmarc provides three types of beamspliiters; Plate Beamsplitters, Cube Beamsplitters, and Variable Beamsplitters. Plate beamspliiters and cube beamsplitters are available with 30 / 70, 50 / 50, or 70 / 30 R/T ratios, while variable beamsplitters provide continuous R/T ratio from 10 / 90 to 90 / 10. In addition to the beamsplitters, Holmarc provides beam samplers to take off a sample of light by Fresnel reflection. All the beamsplitters are coated with Anti-reflection coating to reduce the back reflection. Beamsplitters with custom split ratios and sizes can be supplied to order.
