SLB-30-80NIR2 30.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-30-80NIR2 is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of -80.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared (NIR) applications.
The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties and versatility. The lens features a plano surface on one side and a concave surface on the other, with a center thickness of 2.0 mm and an edge thickness of 4.8 mm. The inner and outer radii are both 0, indicating a simple, straightforward design.
The SLB-30-80NIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance within its specified wavelength range, improving transmission and reducing reflection. According to the vendor, the coating and the lens itself are currently in stock, ensuring availability for immediate use.
