68-377 50 x 75 mm 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm
The 68-377 50 x 75 mm 20:80 (R:T) N-BK7 Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter, with dimensions of 50 x 75 mm, is designed for use in the visible light spectrum, specifically between 400-700nm.
The beamsplitter is made from N-BK7, a popular optical glass due to its excellent optical properties and relatively low cost. The glass has a thickness of 3mm, providing durability and stability. The beamsplitter is coated with EDM 68-363 on the front surface, which is designed to optimize its performance in the visible light spectrum.
This beamsplitter is a thin BS type, meaning it is designed to be thin and lightweight, making it ideal for applications where space and weight are critical factors. The beamsplitter's geometry is rectangular, which is a common shape for beamsplitters due to its ease of use and versatility.
The beamsplitter's physical data indicates that it has a reflection of 20% and a transmission of 80% for the reflected and transmitted beams, respectively. This ratio is often used in applications where a high transmission rate is required.
