SLB-30-70NIR1 30.0 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
OptoSigma presents the SLB-30-70NIR1, a Plano-Concave Spherical Lens with a 30.0 mm diameter and a focal length of -70.0 mm. This lens is designed for use within the wavelength range of 633-1064nm, making it suitable for various applications in the near-infrared spectrum.
The lens is made from the highly versatile material n-BK7 Schott, which is known for its excellent optical properties and low auto-fluorescence. The Plano-Concave geometry, with inner and outer radii of 0 mm, ensures the desired light bending and focusing capabilities. The lens has a thickness of 5.2 mm at the edge and 2 mm at the center, contributing to its robustness and overall optical performance.
The SLB-30-70NIR1 features a front and back coating of opt IR1, enhancing its transmission capabilities within the specified wavelength range. This coating helps minimize surface reflections and optimizes the lens's performance in the near-infrared spectrum.
