LWP: Long Wave Pass Dichroic Beamsplitter

LWP: Long Wave Pass Dichroic Beamsplitter

LWP: Long Wave Pass Dichroic Beamsplitter

High efficiency, high power long wave pass beam splitting for any polarization. Ultra-high reflectivity at a single wavelength combined with high transmission over a broad band of longer wavelengths allow for efficient beam separation or mixing at UV through near-infrared wavelengths. With durable dielectric and AR coatings, these plate beamsplitters perform at high power and any polarization.
