This is a 14NBC-10-50/50-700-950 Non-Polarizing Cube Beamsplitter, offered by Standa. It is a precision optical component designed for applications that require the splitting of an incident light beam into two separate beams of equal intensity. The beamsplitter is constructed with a 10 x 10 x 10 mm S-BSL7 cube, a high-quality optical material from Ohara.
The beamsplitter has a 50:50 reflection-to-transmission ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This characteristic is consistent across the 700-950nm wavelength range, making it suitable for a wide range of applications in this spectral region.
The beamsplitter's coating is another notable feature. Both the front and back surfaces, as well as the left and right surfaces, are coated with an ideal broadband anti-reflective (AR) coating. This coating reduces unwanted reflections and increases the overall transmission of the beamsplitter.
The hypotenuse faces of the beamsplitter are also treated with specific coatings. Hypotenuse 1 is coated with Sta 14NBC-700-950, while Hypotenuse 2 is coated with an ideal broadband AR coating. These coatings are designed to optimize the beamsplitter's performance in its intended application.
