SLB-20-120NIR1 20.0 mm Dia. x -120.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-20-120NIR1 is a Plano-Concave Spherical Lens, 20.0 mm in diameter, with a focal length of -120.0 mm, sourced from OptoSigma. This lens is designed for use within the wavelength range of 633-1064nm, making it suitable for a variety of applications within this spectrum.
The lens is crafted from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens features a plano surface on one side and a concave surface on the other, with an inner radius of 0mm and an outer radius of 0mm. The edge thickness of the lens is 2.8mm, while the center thickness is 2mm, providing a robust and durable structure.
The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating helps to reduce reflection and increase transmission, thereby improving the overall efficiency of the optical system in which it is used.
The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status. For more detailed information or to make a purchase, users are directed to the vendor's website via the provided weblink.
