68-430 50 x 50 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-430 is a high-quality beamsplitter from Edmund Optics, designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100nm. This beamsplitter is rectangular in shape, with dimensions of 50 x 50 mm, and has a thickness of 3mm, providing excellent stability and durability.

The beamsplitter is made from N-BK7 glass, a popular choice due to its excellent optical properties and wide transparency range. The N-BK7 Schott material ID ensures that the glass meets the high standards set by Schott, a leading manufacturer of optical glass.

The beamsplitter features a coating on the front surface, specifically the EDM 68-418 coating. This coating is designed to enhance the performance of the beamsplitter, particularly in terms of its reflectance and transmittance characteristics. According to the item data, the beamsplitter has a reflection of 0.8 and a transmission of 0.2, indicating a typical 80:20 (R:T) split.

The beamsplitter is classified as a thin BS, which refers to its 'thin lens' shape. This shape is often preferred in optical systems where space is at a premium, as it minimizes the overall thickness of the optical element.
