49-753 35 x 35 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
The 49-753 is a rectangular beam splitter, measuring 35 x 35 mm, with a thickness of 3mm, sourced from the renowned optical vendor, Edmund Optics. This beamsplitter is designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100nm.
The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications that require high homogeneity, low auto-fluorescence, and good thermal stability.
The beamsplitter features a 30:70 (R:T) reflectance to transmission ratio, meaning it reflects 30% of the incident light and transmits 70%. This ratio is crucial in determining the beamsplitter's performance in various optical systems.
The front surface of the beamsplitter is coated with EDM 48-389, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance in the NIR spectrum, ensuring optimal reflection and transmission rates.
The beamsplitter's thin lens shape allows for easy integration into various optical systems. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
