BICV308 38 mm Dia. x -700 mm FL; Uncoated; Double-Concave Lens

The BICV308 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 38 mm and a focal length of -700 mm. This lens is designed for use in optical systems that require a negative focal length, making it suitable for applications such as beam expansion or collimation.

The lens is spherical in shape, featuring a double-concave design with radii of curvature of -725.6 mm for the first surface and 725.6 mm for the second. This specific curvature allows for precise control over the path of light rays, enhancing the performance of your optical system. The lens has an edge thickness of 3.5 mm and a center thickness of 3 mm, providing a robust structure while maintaining a high level of optical performance.

The BICV308 is made from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses, but it also means the lens is less susceptible to damage from environmental factors or handling.
