35-949 12.5 mm Dia. 70:30 (R:T) N-BK7 Plate Beamsplitter; t=1mm VIS 400-700nm

This 35-949 Beamsplitter, sourced from Edmund Optics, is a circular plate with a diameter of 12.5 mm and a thickness of 1 mm. It is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The beamsplitter is designed to reflect 70% of the incident light and transmit 30%, making it suitable for various applications where light needs to be divided.

The beamsplitter's coating, EDM 48-394, is applied to the front surface. This coating enhances the beamsplitter's performance in the visible light spectrum, specifically between 400 and 700 nm. The coating ensures high reflectivity and transmission, contributing to the overall efficiency of the optical system.

The 35-949 Beamsplitter is a thin lens, which means it is lightweight and less prone to optical distortions compared to thicker lenses. It is currently in stock, as indicated by its weblink status, making it readily available for your optical system needs.
