The SLB-15B-90PIR1 is a spherical lens with a base shape of a circle, offering a diameter of 15.0 mm and a focal length of 90.4 mm. This lens is sourced from OptoSigma, a reputable vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice due to its excellent optical properties.
The lens features a double-convex geometry, with radii of curvature of 93.42 mm for the first surface and -93.42 mm for the second surface. This specific lens design allows for a broad range of applications, particularly in systems where a high numerical aperture is required.
The lens has a central thickness of 2.6 mm and an edge thickness of 2 mm, providing robustness and durability. The effective focal length (EFL) is 90.4 mm, and the back focal length (BFL) is 89.6 mm. The lens does not have an inner or outer radius.
The SLB-15B-90PIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 633 and 1064 nm. The coating ensures high transmission and reduces reflection, making it suitable for applications that require optimal light transmission.
