SLB-20-170P 20.0 mm Dia. x 170.0 mm FL; Plano-Convex Lens Uncoated
The SLB-20-170P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 170.0 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 known for its excellent transparency and low auto-fluorescence.
The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 2.6 mm. The effective focal length (EFL) is 170.0 mm, and the radius of curvature (R1) is 88.23 mm. The back focal length (BFL) is 168.2 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the non-curved side of the lens.
The lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This can be beneficial in certain applications where specific coatings may interfere with the desired optical properties. However, it's important to note that uncoated lenses can have higher reflectivity, which may require additional considerations for your specific application.
The lens is in stock and available for immediate purchase. For more information, you can visit the vendor's website using the provided weblink.
