The 48-899 is a 25 x 25 mm rectangular beamsplitter, designed with a 30:70 (R:T) reflectance-to-transmission ratio, specifically engineered for the Near-Infrared (NIR) spectrum of 700-1100nm. This beamsplitter is manufactured by Edmund Optics, a leading provider of optical components.
The beamsplitter is constructed from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility. The glass has a thickness of 3mm, providing durability while maintaining a low profile. The beamsplitter's coating, EDM 48-389, is applied to the front surface, enhancing its performance within the specified NIR range.
The beamsplitter's physical data indicates a reflection of 0.3 (30%) and transmission of 0.7 (70%). This ratio is ideal for applications where a balance between reflected and transmitted light is required. The beamsplitter's thin lens shape allows for easy integration into various optical systems.
