68-419 12.5 x 17.5 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 68-419 Beamsplitter, 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 mm, and has a thickness of 3mm, providing robustness and stability in its operation.

The beamsplitter is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transparency range. This material ensures high-quality performance and durability. The beamsplitter features a thin lens shape, which is advantageous in many applications due to its reduced weight and potential for lower aberrations.

The coating on the beamsplitter is EDM 68-417, which is specifically designed for this type of optical component. This coating ensures a reliable 80:20 split of the incoming light, with 80% being reflected and 20% being transmitted. This ratio makes it ideal for various applications where a balance between reflection and transmission is required.
