BICV205 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens

The BICV205 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 25.4 mm and a focal length of -75 mm. This lens is designed for use in optical systems that require a negative focal length, making it suitable for applications such as beam compression or image reduction.

The lens is manufactured from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The base shape is circular, and the lens features a double-concave geometry, with radii of curvature of -77.09 mm and 77.09 mm for the first and second surfaces, respectively. The center thickness of the lens is 2 mm, while the edge thickness is 4.11 mm, providing robustness and durability.

The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This may be suitable for applications where such coatings are not required or desirable. However, users should be aware that uncoated lenses can suffer from increased reflection losses, which may affect the performance of the optical system.

The lens is in stock and available for immediate purchase. More information, including technical specifications and pricing, can be found on the WTS Photonics website.
