BSP0150-9R7 50.8 mm Dia. 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm 900-1200nm
This Union Optic beamsplitter, model BSP0150-9R7, is a circular plate with a diameter of 50.8 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 900-1200nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum. It features a 30:70 (R:T) reflectance-to-transmission ratio, meaning that approximately 30% of the incident light is reflected while 70% is transmitted. This ratio is uniform across the entire surface of the beamsplitter, ensuring consistent performance.
The front surface of the beamsplitter is coated with a uni bsp3070900120045 coating, which is specifically designed to enhance its performance in the intended wavelength range. This coating helps to maintain the desired reflectance-to-transmission ratio and also provides protection against environmental factors that could degrade the optical surface.
