The SLB-50.8B-120PIR1 is a spherical lens with a base shape of a circle, offering a diameter of 50.8 mm and a focal length of 121.3 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality optical glass, and features a double-convex geometry, making it suitable for a wide range of optical applications.
The lens has a thickness of 2.8 mm at the edge and 8 mm at the center, providing a robust structure and ensuring optimal performance. The inner and outer radii are 0, indicating a symmetrical design. The effective focal length (EFL) is 121.3 mm, and the back focal length (BFL) is 118.6 mm, providing a clear focus and minimal distortion.
The SLB-50.8B-120PIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its transmission capabilities within the wavelength range of 633-1064nm. This coating ensures high-quality image reproduction and reduces unwanted reflections, making it an ideal choice for applications that require high transmission and low loss.
