EKSMA Optics Non-Polarizing Broadband Cube Beamsplitters
145.45 kB |
Non-polarizing cube beamsplitters are made of two right angle prisms cemented together with a partially reflecting surface on the internal (protected) face. Four sides of the beamsplitter cubes are broadband anti-reflection coated. The coatings are designed for 450-700 nm or 750-1100 nm range.
Cubes provide 50:50 split ratio and come in four different sizes. Cubes can be supplied unmounted or mounted, mounted cubes have codes with M2Ps or M2P suffixes.
