35-932 12.5 x 17.5 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=1mm VIS 400-700nm

This 35-932 Beam Splitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the visible light spectrum, specifically between 400 and 700 nanometers. The beamsplitter is rectangular in shape, with dimensions of 12.5 x 17.5 millimeters, and has a thickness of 1 millimeter.

The beamsplitter is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high damage threshold. This material is particularly suitable for applications in the visible and near-infrared regions.

The beamsplitter 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 consistent across the specified wavelength range.

The front surface of the beamsplitter is coated with EDM 48-388, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance in the visible spectrum, ensuring high transmission and reflection efficiency.

The beamsplitter is designed in the shape of a thin lens, which not only provides excellent optical performance but also minimizes the impact of thickness on the overall performance. This makes it an ideal choice for applications where space is a constraint.
