BK7-LNPBSC-12.7-780 12.7 x 12.7 x 12.7 mm N-BK7 Laser Line Non-Polarizing Cube Beamsplitter 780nm

The BK7-LNPBSC-12.7-780 is a high-quality non-polarizing cube beamsplitter, designed for use in laser line applications at a wavelength of 780nm. This beamsplitter is sourced from Simtrum, a reputable vendor known for their extensive catalog of optical elements.

The beamsplitter is constructed from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The geometry of the beamsplitter is a cube, with each side measuring 12.7mm, making it compatible with a wide range of optical systems.

The beamsplitter features a broadband anti-reflective (AR) coating on the front, back, left, and right surfaces, and a simulated non-polarizing beamsplitter coating (NPBS) with 780nm central wavelength and 45-degree angle of incidence (AOI) on one of the hypotenuse surfaces. The other hypotenuse surface is coated with a broadband AR coating. This specific coating configuration ensures high transmission and reflection at the specified wavelength, making it ideal for laser line applications.

The beamsplitter's physical data indicates a reflection of 0.5 and a transmission of 0.5 at the beamsplitter surface, demonstrating its balanced performance. The beamsplitter's shape is a cube, which is a common and versatile design in optical systems due to its robustness and ease of alignment.
