SLB-20-50NIR1 20.0 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

OptoSigma's SLB-20-50NIR1 is a plano-concave lens with a diameter of 20.0 mm and a focal length of -50.0 mm. This lens is made from n-bk7 schott, a material known for its excellent optical properties. The lens's geometry includes a thickness edge of 4.0 mm and a thickness center of 2.0 mm, making it suitable for a wide range of optical applications.

The lens's coating, opt ir1, is applied to both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating is specifically designed to optimize the lens's performance in the near-infrared spectrum, making it an ideal choice for applications such as laser systems, spectroscopy, and imaging.

The lens's shape is spherical, a common and versatile geometry in optical systems. The inner and outer radii are 0.0 mm, indicating a plano surface on one side and a concave surface on the other. This shape, combined with the lens's other specifications, makes it a highly functional and adaptable optical component.

According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. The website also provides further technical details and specifications, as well as options for customization.
