15mm 30R/70T In-Line Cube Beamsplitter

Product Details Significantly Reduces Glare and Interference 30/70 Reflection/Transmission Ratio Ideal for In-Line Illumination Cube Beamsplitters Also Available TECHSPEC In-Line Illumination Cube Beamsplitters are specialized versions of TECHSPEC Cube Beamsplitters that include a proprietary surface treatment on one surface. This feature reduces glare, interference artifacts, and improves image contrast. Output is partially polarized, making TECHSPEC In-Line Illumination Cube Beamsplitters suitable for illumination, specifically in applications sensitive to ghost reflections, and other applications where polarization is not a concern. TECHSPEC In-Line Illumination Cube Beamsplitters feature an interference coating applied to the hypotenuse of one of the prisms to provide the designated reflection/transmission ratio. Absorption loss to the coating is minimal. Note: If polarization sensitivity is critical to your application, we recommend using TECHSPEC Polarizing Beamsplitters or TECHSPEC Non-Polarizing Beamsplitters .
