NPCH-20-15500 20 x 20 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=20mm 1550nm
The NPCH-20-15500 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in optical systems operating at a wavelength of 1550nm. This beamsplitter features a 20mm x 20mm aperture and offers a 50:50 (R:T) split, meaning it reflects and transmits 50% of the incident light, respectively.
The beamsplitter is constructed from N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission properties in the near-infrared region. The cube shape of the beamsplitter allows for easy integration into various optical setups.
The NPCH-20-15500 is coated with ideal broadband anti-reflection (AR) coatings on all surfaces, including the hypotenuse faces. This coating helps to minimize reflection losses and improve overall transmission, enhancing the performance of your optical system.
