68-386 25 mm Dia. 40:60 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-386 is a 25 mm diameter 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 vendor in the optical industry, and is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.

This beamsplitter is of the thin BS subtype, featuring a circular geometry with a diameter of 25mm and a thickness of 3mm. It is made from N-BK7, a high-quality borosilicate glass manufactured by Schott, which is known for its excellent optical properties and durability.

The beamsplitter's coating is a crucial component of its design. The front surface is coated with EDm 68-382, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance, particularly in terms of its reflection and transmission characteristics.

In terms of physical data, the beamsplitter has a reflection rate of 40% and a transmission rate of 60%. This means that 40% of the incident light will be reflected, while 60% will be transmitted through the beamsplitter. This ratio is often crucial in optical systems, making this beamsplitter a valuable component for a wide range of applications.
