BICV103 12.7 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens
The BICV103 is a high-precision double-concave lens, 12.7 mm in diameter, manufactured by WTS Photonics. This lens boasts a focal length of -25 mm, making it suitable for applications requiring concave-concave lenses. The lens is uncoated, offering a cost-effective solution for general-purpose use.
The lens's geometry is characterized by its double-concave shape, with a center thickness of 2 mm and an edge thickness of 3.62 mm. The radii of curvature for the first and second surfaces are -25.35 mm and 25.35 mm, respectively. The back focal length measures 23.82 mm, and the lens has no inner or outer radius, indicating a uniform curvature across its surface.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to operate at a wavelength of 546.1 nm, making it suitable for a wide range of applications.
