BTF: Standard Plate Beamsplitter

BTF: Standard Plate Beamsplitter

BTF: Standard Plate Beamsplitter

Economical 30/70, 50/50, or 70/30 splitting of unpolarized light at visible wavelengths (400-800 nm). An economical solution for broadband power splitting and beam combining of unpolarized light at visible wavelengths (425-675 nm). These plate beamsplitters are AR-coated for very low loss, and are available with standard 30/70, 50/50, or 70/30 split ratios. Custom sizes and shapes are available upon request.
