14BCV75-1-1 25.4 mm Dia. x -75 mm FL; Uncoated; Double-Concave Lens
The 14BCV75-1-1 is a high-quality double-concave lens, sourced from the reputable vendor Standa. This lens is specifically designed for use in optical systems that require concave-concave geometry. The lens boasts a base shape of a circle, with a diameter of 25.4 mm, making it suitable for a wide range of applications.
The lens has a center thickness of 3.7 mm and an edge thickness of 4.7 mm, providing a robust structure while maintaining a compact profile. The effective focal length (EFL) of this lens is -75 mm, indicating its double-concave nature. The radii of curvature for the first and second surfaces are -78.43180332 mm and 78.43180332 mm, respectively.
The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties and durability. The lens is designed to operate at a wavelength of 546 nm. The lack of a coating suggests that this lens is uncoated, which may be suitable for applications where anti-reflection coatings are not required.
