SLB-20-90PM 20.0 mm Dia. x 90.0 mm FL; Coated; Plano-Convex Lens 400-700nm

The SLB-20-90PM is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens boasts a diameter of 20.0 mm and a focal length of 90.0 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 geometry is characterized by a thickness of 2.0 mm at the edge and 3.1 mm at the center. The front and back surfaces of the lens are coated with an opt m coating, designed to enhance the lens's performance in the 400-700nm wavelength range. This coating helps to reduce surface reflections and increase transmission, making the lens ideal for use in laser applications and other settings where high light transmission is required.

The lens's design includes an inner radius of 0 mm and an outer radius of 0 mm, contributing to its high-performance capabilities. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in various optical systems.
