SLB-25.4B-200NIR1 25.4 mm Dia. x -199.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-25.4B-200NIR1 is a high-quality double-concave lens, 25.4 mm in diameter, designed for use in the 633-1064nm wavelength range. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical components.
The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties. It features a base shape of a circle, with a thickness of 2.8 mm at the edge and 2 mm at the center. The effective focal length (EFL) of this lens is -199.7 mm, making it suitable for a variety of applications that require a negative focal length.
The radii of curvature for this lens are -207.6 mm for the first surface and 207.6 mm for the second surface. The back focal length (BFL) is -200.4 mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
The SLB-25.4B-200NIR1 comes with a coating of opt ir1 on both the front and back surfaces. This coating enhances the lens' performance in the infrared region, making it ideal for applications that use these wavelengths.
