36-659 50 mm Dia. 50:50 (R:T) ZnSe Infrared Plate Beamsplitter; t=3mm 2-20µm

The 36-659 is a 50 mm diameter Zinc Selenide (ZnSe) Infrared Plate Beamsplitter, with a thickness of 3mm and a wavelength of 10600 nm. This beamsplitter is designed to equally reflect and transmit infrared light, making it ideal for applications that require balanced light distribution.

The beamsplitter's geometry includes a 50 mm diameter and a 3mm thickness, ensuring durability and stability. It is made from ZnSe, a material known for its excellent optical properties in the infrared spectrum. The beamsplitter's coating, edm 36-658, is applied to the front surface to enhance its performance.

The 36-659 is available from Edmund Optics and is currently in stock. It is classified as a Thin BS, which refers to its thin lens shape. The physical data indicates a 50% reflection and 50% transmission rate, demonstrating its balanced light distribution capabilities.

This beamsplitter is suitable for various applications, particularly those that involve infrared light. Its balanced light distribution, robust construction, and high-quality coating make it a reliable choice for optical systems that require precise light control.
