SLB-20-200PIR1 20.0 mm Dia. x 200.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-20-200PIR1 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 200.0 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 edge thickness of the lens is 2.0 mm, while the center thickness is 2.5 mm, providing a robust structure that can withstand typical handling and usage.
The SLB-20-200PIR1 comes with a broadband anti-reflection coating, specifically designed for the infrared region (opt ir1). This coating, applied to both the front and back surfaces, reduces reflective losses, enhancing the overall transmission of the lens. The coating is suitable for wavelengths ranging from 633 to 1064 nm, making it ideal for near-infrared and shortwave-infrared applications.
