The SLB-20-120PIR1 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 120.0 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 transparency and low auto-fluorescence.
The lens features a Plano-Convex geometry, meaning one side is flat (plano) and the other side is curved (convex). This design allows for efficient light gathering and focusing. The lens has a thickness of 2.0 mm at the edge and 2.8 mm at the center, providing a robust structure while maintaining a low profile.
The SLB-20-120PIR1 comes with a coating of opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared region of the spectrum, specifically between 633 and 1064 nm. The coating reduces reflection and increases transmission, making it ideal for use in IR applications.
