Our laser line plate beamsplitters feature a 50R/50T ratio and are insensitive to input beam polarization. Available in 12.5mm and 25mm diameters as well as 50mm square, the beamsplitters feature high damage thresholds and can be easily integrated into a variety of laser applications. The beamsplitter coating is complemented by a high efficiency AR V-coating for enhanced performance. A precision excimer grade UV grade fused silica substrate, featuring a 10-5 surface quality and 5 arc second parallelism, provides excellent thermal stability, low wavefront distortion, and ultra-low auto-fluorescence.12.5mm and 25mm uncoated substrates are available as well. Please contact us for 30 arc minute wedged versions of these beamsplitters.
