SLB-50B-100NM 50.0 mm Dia. x -99.5 mm FL; Coated; Double-Concave Lens 400-700nm
The SLB-50B-100NM is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use within the wavelength range of 400-700nm, is ideal for applications such as imaging, beam shaping, and light collimation.
The lens boasts a base shape of a circle with a diameter of 50.0 mm, providing a wide area for light transmission. The edge thickness measures 9.1 mm, while the center thickness is 3.0 mm, ensuring robustness and durability. The effective focal length (EFL) of this lens is -99.5 mm, making it suitable for use in systems requiring strong negative lensing.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it suitable for a wide range of applications.
The SLB-50B-100NM features a coating of opt m on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
