The SLB-10-80NIR2 is a plano-concave lens with a diameter of 10.0 mm and a focal length of -80.0 mm, specifically designed for use in the spectral range of 750-1550nm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements.
The lens is made of n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The plano-concave geometry, characterized by a flat front surface and a curved back surface, is ideal for applications that require light collimation or reduction of beam divergence.
The lens has a central thickness of 2.0 mm and an edge thickness of 2.3 mm, providing robustness and durability. The back focal length (BFL) is -81.3 mm, and the effective focal length (EFL) is -80.0 mm, indicating a strong converging capability.
The lens features a coating of opt ir2 on both the front and back surfaces, enhancing its performance in the specified wavelength range. This coating reduces reflection and increases transmission, making the lens suitable for applications that require high light throughput and low loss.
