BSP0125-4R8 25.4 mm Dia. 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm 400-700nm

This Union Optic beamsplitter, model BSP0125-4R8, is a circular plate with a diameter of 25.4 mm and a thickness of 3 mm. It is designed for use in the visible spectrum, specifically between 400 and 700 nm. The beamsplitter is made of N-BK7, a popular optical glass known for its excellent optical properties and wide transmission range.

The beamsplitter features a 20:80 (R:T) coating on the front surface, which means that it reflects 20% of the incident light and transmits 80%. This coating is uni bsp208040070045, a specific type of coating optimized for the 400-700 nm wavelength range. The beamsplitter's geometry is that of a thin lens, making it suitable for use in various optical systems where a flat beamsplitter might cause unwanted reflections or other optical aberrations.
