PSCH-50C05-10-550 50 mm Dia. N-BK7 Chromium Half-Mirror Plate Beamsplitter; t=5mm 400-700nm
The PSCH-50C05-10-550 is a high-quality beamsplitter from OptoSigma, designed with a chromium coating on a 50 mm diameter N-BK7 Schott glass substrate. This beamsplitter is specifically engineered for use in the 400-700nm wavelength range, making it suitable for a wide range of optical applications.
The beamsplitter is thin, with a thickness of 5mm, and features a half-mirror design. This design allows for 70% (0.7) of the incident light to be reflected, while 30% (0.3) is transmitted. The N-BK7 Schott glass, a borosilicate crown glass, is known for its excellent optical properties, including low autofluorescence, high homogeneity, and excellent transmission in the visible spectrum.
The beamsplitter's chromium coating, denoted as 'opt psch-550', is optimized for a wavelength of 550nm. This coating ensures high reflectivity at this wavelength, while still allowing for reasonable transmission. The coating is applied to the front surface of the beamsplitter, ensuring that the back surface remains uncoated for optimal performance.
