SLB-25.4B-150NIR1 25.4 mm Dia. x -149.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-25.4B-150NIR1 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 in the optical industry, and is currently in stock, as indicated by its weblink status.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. It features a base shape of a circle, with a thickness of 3 mm at the edge and 2 mm at the center. The effective focal length (EFL) of this lens is -149.7 mm, making it suitable for a variety of applications that require a negative focal length.
The radii of curvature for this lens are -155.7 mm for the first surface and 155.7 mm for the second surface. The back focal length (BFL) is -150.4 mm. Notably, the inner and outer radii are both 0, indicating that this lens does not have any special shaping on its edges.
The lens comes with a coating of opt ir1 on both the front and back surfaces. This coating is specifically designed for use in the infrared region, enhancing the lens' performance in its intended wavelength range.
