BK7-BSP-50.8-650-900-40:60 50.8 mm Dia. N-BK7 60:40 (R:T) Broadband Plate Beamsplitter; t=3mm 650-900nm

This Beam Splitter, sourced from Simtrum, is a high-quality optical component designed for precise light manipulation. Its primary function is to divide incoming light into two separate beams, with a specified reflection and transmission ratio.

The Beam Splitter features a circular geometry with a diameter of 50.8 mm and a thickness of 3 mm, providing a robust and compact design. The material of choice is N-BK7, a type of borosilicate glass known for its excellent optical properties, including high transparency and low auto-fluorescence. This specific model is designed to operate within the wavelength range of 650-900 nm.

The coating on the front surface of the Beam Splitter is sim bs406065090045, a proprietary coating developed by Simtrum. This coating ensures the specified light division ratio of 60:40 (R:T), where 'R' represents reflection and 'T' represents transmission. In other words, 60% of the incoming light will be reflected, while 40% will be transmitted.

This Beam Splitter is a Thin Lens type, which means it has a thin, flat design, making it ideal for applications where space is limited. The physical data indicates that the reflection and transmission coefficients are 0.6 and 0.4, respectively, aligning with the specified 60:40 (R:T) ratio.
