This is a 30 mm diameter N-BK7 Chromium Half-Mirror Plate Beamsplitter, specifically designed for use in the 750-850nm wavelength range. The beamsplitter is sourced from OptoSigma, a renowned vendor in the optical industry, and is available for purchase directly from their website.
The beamsplitter is a thin BS type, featuring a circular base shape and a thickness of 3mm. It is made from N-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. This makes it an ideal choice for applications that require high precision and clarity.
The front surface of the beamsplitter is coated with an OPT PSCH-800 coating. This coating is specifically designed to optimize the beamsplitter's performance at the 800nm wavelength, ensuring high reflection and transmission rates. According to the provided specifications, the beamsplitter has a reflection rate of approximately 70% and a transmission rate of approximately 30% at this wavelength.
