49-752 35 x 35 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm
This 49-752 Beamsplitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the visible light spectrum, spanning from 400 to 700 nanometers. The beamsplitter is rectangular in shape, with dimensions of 35 x 35 mm, and has a thickness of 3mm, making it a robust and stable choice for various optical applications.
The beamsplitter is made from N-BK7, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for use in beam splitting applications.
The coating on the beamsplitter is EDM 48-388, which is specifically designed for the visible light spectrum. This coating ensures a 30:70 (R:T) split, meaning that 30% of the incident light is reflected, while 70% is transmitted. This ratio is crucial in many optical systems, such as interferometers and beam combiners.
The beamsplitter is designed in a thin lens shape, which minimizes optical aberrations and ensures a high-quality split of the incident light. This makes it suitable for use in precision optical systems where minimal distortion is required.
