KBC037 25.4 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens

The KBC037 is a high-quality spherical lens, specifically designed for use in optical systems that require a concave-concave lens shape. This lens is sourced from the reputable vendor MKS/Newport, and its detailed specifications make it a versatile component for a wide range of applications.

The lens has a diameter of 25.4 mm and a center thickness of 2.5 mm, with an edge thickness of 3.76 mm, providing a robust and durable structure. The base shape is circular, ensuring easy integration into various optical setups. The effective focal length (EFL) of this lens is -100 mm, making it suitable for use in systems where negative focal length is required.

The KBC037 is made from the high-grade material N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low auto-fluorescence and high transmittance in the visible spectrum. The radii of curvature for this lens are r1=-103.785 mm and r2=103.785 mm, with a back focal length (BFL) of -100.82 mm. The lens does not have any coating, which makes it suitable for applications where coating is not required or preferred.

This lens is designed to work optimally at a wavelength of 589 nm, making it suitable for use in systems operating in the yellow-orange part of the visible light spectrum. The KBC037 is a valuable addition to any optical system that requires a high-quality, double-concave lens.
