48-400 25 x 38 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 48-400 Plate 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 25 x 38 mm, and has a thickness of 3mm, providing robustness and stability in its operation.

The beamsplitter is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. This material is known for its low auto-fluorescence, making it ideal for applications that require high sensitivity and low background noise.

The beamsplitter features a 70:30 (R:T) coating, which means that approximately 70% of the incident light is reflected, while the remaining 30% is transmitted. This specific ratio is often used in applications where a balance between reflection and transmission is required. The coating is identified as "edm 48-394", according to the vendor's classification system.

The beamsplitter's thin lens shape allows for efficient light manipulation and minimal distortion. This makes it suitable for a wide range of applications, including but not limited to, interferometry, holography, and beam combining.
