BICV203 25.4 mm Dia. x -35 mm FL; Uncoated; Double-Concave Lens

The BICV203 is a high-precision double-concave lens, sourced from WTS Photonics, with a diameter of 25.4 mm and a focal length of -35 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, collimation, and image reduction.

The lens is made from n-BK7 Schott glass, a popular material due to its excellent optical properties and high Abbe number. The base shape of the lens is circular, and it features a double-concave geometry with radii of curvature of -35.08 mm and 35.08 mm. The center thickness of the lens is 2 mm, while the edge thickness is 6.76 mm, providing robustness and durability.

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

The lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website, where you can find detailed specifications, pricing, and ordering information.
