68-365 12.5 x 17.5 mm 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 68-365 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 3 millimeters.

The beamsplitter is made from N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. This material is known for its low auto-fluorescence, high damage threshold, and excellent transmission in the visible and near-infrared spectral regions.

The beamsplitter features a 20:80 (R:T) coating, which means that it reflects 20% of the incident light and transmits 80%. The coating is applied to the front surface of the beamsplitter, as indicated by the "edm 68-363" coating parameter.

This beamsplitter is a thin lens type, which means it is designed to minimize optical aberrations and distortions. This makes it ideal for use in applications where high optical precision is required, such as in imaging systems, interferometers, and laser systems.

The beamsplitter is currently in stock and available for purchase through the Edmund Optics website, as indicated by the "weblink status" parameter. For more information, please refer to the provided weblink.
