BICV208 25.4 mm Dia. x -150 mm FL; Uncoated; Double-Concave Lens

The BICV208 is a high-precision double-concave lens, 25.4 mm in diameter, and featuring a focal length of -150 mm. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity.

The lens geometry is characterized by its concave-concave shape, with a thickness of 3.04 mm at the edge and 2 mm at the center. The effective focal length (EFL) is -150 mm, and the back focal length (BFL) is 149 mm. The radii of curvature for the first and second surfaces are -155.1 mm and 155.1 mm, respectively. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.

This lens is designed to operate at a wavelength of 546.1 nm, making it suitable for a wide range of applications in fields such as metrology, interferometry, and beam shaping. Its double-concave design allows for effective divergence of light beams, making it an ideal choice for applications requiring beam conditioning.

Please note that the lens is uncoated, which means it may not perform optimally in high-intensity or high-precision applications. However, for applications where coating is not a requirement, this lens offers a cost-effective solution with reliable performance.
