SLB-10-70NIR2 10.0 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-10-70NIR2 is a plano-concave lens with a diameter of 10.0 mm and a focal length of -70.0 mm, specifically designed for use in the infrared spectrum, between 750nm and 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 low auto-fluorescence. The plano-concave geometry, where one surface is flat and the other is curved, is ideal for applications requiring light collimation or reduction of beam divergence.
The lens features a front and back coating of opt ir2, which enhances its performance in the infrared spectrum. This coating reduces surface reflections, improving the overall transmission of the lens. The edge thickness is 2.3 mm, while the center thickness is 2 mm, providing a robust and durable structure.
The SLB-10-70NIR2 is currently in stock and available for immediate purchase. For more information, including technical specifications and pricing, please refer to the vendor's website using the provided weblink.
