BAN2503 15 x 25 mm 50:50 (R:T) White Float Glass Standard Plate Beamsplitter; t=3mm 1050-1700nm

This Knight Optical beam splitter, model BAN2503, is a high-quality optical component designed for use in the near-infrared (NIR) and telecom spectrum, specifically at a wavelength of 1064nm. The beam splitter is rectangular in shape, with dimensions of 15 x 25 mm, and has a thickness of 3mm.

The beam splitter is made of soda lime glass, a common material in optical applications due to its excellent optical properties and durability. The front surface of the beam splitter is coated with a bi-layer coating, denoted as "kni bi2", while the back surface is coated with a different bi-layer coating, "kni ai2". These coatings are designed to enhance the beam splitter's performance at the specified wavelength.

The beam splitter operates on a 50:50 (R:T) basis, meaning it reflects 50% of the incident light and transmits the remaining 50%. This makes it ideal for applications where equal distribution of light is required. The physical data provided indicates a reflection of 0.5 and a transmission of 0.5, further confirming its 50:50 operation.
