SLB-15-40PM 15.0 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 400-700nm

The SLB-15-40PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a diameter of 15.0 mm and a focal length of 40.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.

The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The curvature of the convex side is defined by a radius of 20.76 mm. The lens has an effective focal length (EFL) of 40.0 mm and a back focal length (BFL) of 37.8 mm. The edge thickness of the lens is 2.0 mm, while the center thickness is 3.4 mm.

The SLB-15-40PM is coated with an Opt M coating on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700nm, making it ideal for use in applications such as fluorescence microscopy, spectroscopy, and other applications that require high transmission and low auto-fluorescence in the visible spectrum.
