48-900 75 x 75 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 48-900 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 75 x 75 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 30:70 (R:T) split, meaning it reflects 30% of the incident light and transmits 70%. This ratio is consistent across the visible light spectrum, making it a versatile component for various applications.

The front surface of the beamsplitter is coated with EDM 48-388, a coating specifically designed to enhance the beamsplitter's performance in the visible light spectrum. This coating ensures optimal reflection and transmission rates, contributing to the overall efficiency and effectiveness of the beamsplitter.
