SLB-50.8-200NIR2 50.8 mm Dia. x -200.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-50.8-200NIR2 is a Plano-Concave Spherical Lens, 50.8 mm in diameter, with a focal length of -200.0 mm, specifically designed for use within the wavelength range of 750-1550nm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and homogeneity properties. The lens's geometry includes a thickness of 6.2 mm at the edge and 3 mm at the center, with an inner radius of 0 mm and an outer radius of 0 mm. The back focal length is -202 mm, and the radius of curvature at the front surface is -103.8 mm.
The SLB-50.8-200NIR2 is coated with Opt IR2, a broadband anti-reflection coating that enhances its performance in the infrared region. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and improving overall transmission.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
