49-757 35 x 35 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 49-757 is a 35 x 35 mm beamsplitter, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm. This beamsplitter is sourced from Edmund Optics, a leading provider of optical components.

The beamsplitter is rectangular in shape, with dimensions of 35mm in width and 35mm in height. It has a thickness of 3mm, providing robustness and stability during operation. The material used for this beamsplitter is N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and high transmittance in the visible and NIR spectra.

The beamsplitter features a 70:30 (R:T) coating, which means that it reflects 70% of the incident light and transmits 30%. This coating is applied to the front surface of the beamsplitter and is identified as EDM 48-395 in the vendor's catalog. This specific coating is designed to optimize performance in the NIR spectrum, making it ideal for applications such as laser systems, bio-imaging, and spectroscopy.

The beamsplitter is designed in a thin lens shape, which minimizes optical aberrations and ensures high-quality performance. The physical data of the beamsplitter indicates a reflection of 0.7 and a transmission of 0.3, aligning with the specified 70:30 (R:T) ratio.
