BSP0125-6R7 25.4 mm Dia. 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm 650-900nm

This Union Optic beamsplitter, model BSP0125-6R7, is a circular plate with a diameter of 25.4 mm and a thickness of 3 mm. It is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transmission range.

The beamsplitter is designed for use in the wavelength range of 650-900nm, making it suitable for a variety of applications in the near-infrared spectrum. The coating on the front surface is uni bsp307065090045, which provides a 30:70 (R:T) split, meaning that approximately 30% of the incident light is reflected while 70% is transmitted.

This beamsplitter is a thin lens type, which means it is designed to minimize optical path differences and wavefront distortions. It is currently in stock and available for purchase through the Union Optic website.
