48-388 12.5 mm Dia. 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 12.5 mm diameter beamsplitter, sourced from Edmund Optics, is a high-quality optical component designed for use in a variety of applications. It features a 30:70 (R:T) reflectance to transmission ratio, making it ideal for scenarios where a balanced split of the incoming light is required.

The beamsplitter is made from N-BK7 Schott glass, a material known for its excellent optical properties and wide transparency range. The glass has a thickness of 3mm, providing durability and stability. The beamsplitter is designed to operate within the visible spectrum, specifically between 400 and 700nm.

The front surface of the beamsplitter is coated with the EDM 48-388 coating, which is specifically designed to ensure the desired reflectance and transmission characteristics. The beamsplitter is shaped as a thin lens, which can be beneficial in certain optical system designs.

According to the provided data, the beamsplitter has a reflection coefficient of 0.3 and a transmission coefficient of 0.7. This means that approximately 30% of the incoming light will be reflected, while the remaining 70% will be transmitted.

The beamsplitter is currently in stock and available for purchase, as indicated by the 'weblink status' field in the item data. For more information, including pricing and availability, please refer to the provided web link.
