The HBCH-15-550 is a Hybrid Half-Mirror Cube Beamsplitter, designed and manufactured by OptoSigma. This beamsplitter is a cube-shaped optical element, with dimensions of 15 x 15 x 15 mm, making it suitable for a wide range of optical applications.
The beamsplitter features a broadband anti-reflective (AR) coating on the front, back, left, and right surfaces, ensuring minimal loss of light due to reflection. The hypotenuse faces 1 and 2 are coated with an optimal broadband AR coating (HBCH-550) and a standard broadband AR coating, respectively. This specific coating configuration is ideal for applications within the wavelength range of 400-700 nm.
The beamsplitter's physical data indicates a reflection of 0.55 (55%) on the base surface and a transmission of 0.45 (45%). This ratio is consistent across the entire specified wavelength range. The material used for this beamsplitter is N-BK7 Schott, a popular choice due to its excellent optical properties and wide transparency range.
