68-396 50 x 75 mm 40:60 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-396 is a rectangular beam splitter, measuring 50 x 75 mm, with a thickness of 3mm, sourced from the renowned optical components vendor, Edmund Optics. This beamsplitter is designed for the Near-Infrared (NIR) spectrum, specifically for wavelengths between 700 and 1100nm.

The beamsplitter is made of 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 N-BK7 material ensures high-quality performance and durability, making it suitable for various applications.

The beamsplitter features a 40:60 (R:T) ratio, meaning it reflects 40% of the incident light and transmits 60%. This ratio is consistent across the specified wavelength range, providing reliable and predictable performance. The coating on the front surface, EDM 68-382, enhances the beamsplitter's performance, ensuring optimal reflection and transmission.

The beamsplitter's thin lens shape allows for easy integration into optical systems, while its rectangular geometry provides flexibility in system design. The beamsplitter's physical data, including its bs reflection of 0.4 and bs transmission of 0.6, further highlight its performance capabilities.
