68-409 35 x 35 mm 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-409 is a 35 x 35 mm rectangular beamsplitter, designed with a 60:40 (R:T) ratio, making it ideal for applications where a higher reflection rate is required. This beamsplitter is made from N-BK7 Schott glass, a material known for its excellent optical properties and wide transparency range. The beamsplitter has a thickness of 3mm, providing robustness and stability.

The beamsplitter is coated with EDM 68-399 on the front surface, enhancing its performance in the visible light spectrum, specifically between 400-700nm. This coating ensures high transmission and reflection rates within this spectrum, making it suitable for various applications in fields such as biomedical imaging, machine vision, and optical metrology.

The 68-409 beamsplitter is designed in a thin lens shape, which not only contributes to its robustness but also minimizes optical aberrations. This design ensures that the beamsplitter provides accurate and precise beam splitting, which is crucial in many optical systems.

In terms of physical data, the beamsplitter has a reflection rate of 0.6 and a transmission rate of 0.4. This ratio is fixed and should be considered when calculating the expected output of your optical system.

The 68-409 beamsplitter is available from Edmund Optics and is currently in stock, ensuring quick delivery and availability for your optical system needs.
