SLB-10B-20NIR2 10.0 mm Dia. x -19.7 mm FL; Coated; Double-Concave Lens 750-1550nm
The SLB-10B-20NIR2 is a high-quality double-concave lens, 10.0 mm in diameter, and featuring a focal length of -19.7 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical components. The lens is made from n-bk7 schott, a material widely used in optical systems due to its excellent optical properties.
The lens geometry is characterized by its concave-concave shape, designed to bend light rays inward towards the optical axis. The inner radius is 0, while the outer radius is also 0, indicating a symmetrical design. The thickness at the edge of the lens is 3.2 mm, and at the center, it is 2 mm, providing a robust structure.
The SLB-10B-20NIR2 is coated with opt ir2 on both the front and back surfaces. This coating enhances the lens' performance in the 750-1550nm wavelength range, making it suitable for near-infrared applications. The coating helps reduce reflection, increase transmission, and protect the lens surface from environmental factors.
This lens is currently in stock and available for immediate use. Its detailed specifications, reliable performance, and wide applicability make it a valuable addition to any optical system.
