SLB-25.4B-60NIR1 25.4 mm Dia. x -59.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-25.4B-60NIR1 is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use in the 633-1064nm wavelength range, is made from n-bk7 schott, a material known for its excellent optical properties.
The lens features a diameter of 25.4mm and a center thickness of 2mm, with an edge thickness of 4.6mm. The double-concave design, characterized by radii of curvature of -62.28mm on both surfaces, results in a back focal length of -60.4mm. This configuration makes it suitable for a wide range of applications that require a negative lens.
The SLB-25.4B-60NIR1 comes with a coating of opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared region, making it an ideal choice for applications such as IR spectroscopy, thermal imaging, and other infrared-based technologies.
