LC1093-C N-BK7 Plano-Concave Lens; Dia:2 in; f=-100.0 mm ARC 1050-1700nm
The LC1093-C is a plano-concave lens with a diameter of 2 inches, featuring a focal length of -100.0 mm. This lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties, making it an ideal choice for various applications. The lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens's geometry is characterized by a planar front surface and a concave rear surface, with a thickness of 10.7 mm at the edge and 4 mm at the center. The effective focal length (EFL) is -100.0 mm, and the radius of curvature (R1) of the concave surface is -51.5 mm. The back focal length (BFL) is -102.6 mm.
This lens is designed to operate within the wavelength range of 1050-1700 nm, making it suitable for near-infrared (NIR) applications. The lens features anti-reflection (AR) coating on both the front and back surfaces, specifically designed for the wavelength range of 1050-1700 nm. This coating reduces surface reflections, thereby improving transmission and overall optical performance.
