35-939 75 x 75 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=1mm VIS 400-700nm

The 35-939 is a 75 x 75 mm rectangular beamsplitter, designed with a 30:70 (R:T) reflectance to transmission ratio. This beamsplitter is made from N-BK7 Schott glass, a material known for its excellent optical properties, making it suitable for a wide range of applications. The beamsplitter has a thickness of 1mm, which is ideal for applications that require a thin optical element.

The beamsplitter is designed to operate within the visible spectrum, specifically between 400-700nm. This makes it suitable for applications that involve visible light, such as biomedical imaging, machine vision, and optical metrology. The coating on the front surface of the beamsplitter is EDM 48-388, which is specifically designed to enhance the beamsplitter's performance within the specified wavelength range.

The beamsplitter's physical data indicates that it reflects 30% of the incident light and transmits 70%. This ratio is fixed and should be taken into account when designing optical systems that incorporate this beamsplitter. The beamsplitter's shape is that of a thin lens, which can be beneficial in certain applications where a flat beamsplitter is not suitable.

This beamsplitter is available from Edmund Optics and is currently in stock, making it a readily available option for those in need of a high-quality beamsplitter for their optical systems.
