This is a 20 x 30 mm N-BK7 Broadband 40:60 (R:T) Plate Beamsplitter, offered by Qioptiq Photonics. The beamsplitter is designed with a rectangular base shape and a thickness of 2.5mm, making it a robust and stable optical component.
The beamsplitter is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range. This beamsplitter is specifically designed for the visible spectrum, with a wavelength of 588nm.
The beamsplitter features a coating on the front surface, specifically the Qio BBBS4060TBP45070 coating. This coating is designed to ensure optimal performance in the specified wavelength range.
In terms of its optical properties, the beamsplitter has a reflection of 0.4 and a transmission of 0.6. This 40:60 splitting ratio (R:T) makes it suitable for a wide range of applications where balanced light division is required.
The beamsplitter is currently in stock and available for purchase. For more information, you can refer to the vendor's website through the provided weblink.
