SLB-20-30PM 20.0 mm Dia. x 30.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-20-30PM is a Plano-Convex Spherical Lens, sourced from OptoSigma, a renowned optical elements vendor. This lens boasts a diameter of 20.0 mm and a focal length of 30.0 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 Plano-Convex geometry, with a center thickness of 5.6 mm and an edge thickness of 2 mm, ensures efficient light transmission and minimal distortion.
The lens's front and back surfaces are coated with an opt m coating, designed to enhance its performance in the 400-700nm wavelength range. This coating improves the lens's light transmission, reduces surface reflections, and protects the lens from environmental factors.
The lens's inner and outer radii are 0, indicating a flat inner surface and a curved outer surface. The effective focal length (EFL) is 30.0 mm, and the back focal length (BFL) is 26.3 mm. The lens's shape is spherical, ensuring consistent optical performance across the entire surface.
