SLB-20-170PM 20.0 mm Dia. x 170.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-20-170PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 20.0 mm and a focal length of 170.0 mm, making it suitable for a variety of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass, and features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 2.0 mm at the edge and 2.6 mm at the center. 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.
The SLB-20-170PM is coated with opt m on both the front and back, which enhances its transmission properties in the spectral range of 400-700nm. This coating ensures high-quality performance and durability, making it an ideal choice for various optical systems.
