SLB-30B-50NIR1 30.0 mm Dia. x -49.7 mm FL; Coated; Double-Concave Lens 633-1064nm

The SLB-30B-50NIR1 is a high-quality double-concave lens, 30.0 mm in diameter, and featuring a focal length of -49.7 mm. This lens is sourced from OptoSigma, a renowned vendor known for its precision optical components.

The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it has a center thickness of 2 mm and an edge thickness of 6.4 mm. The inner and outer radii are both 0, indicating a uniform curvature.

The lens is coated with opt ir1 on 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 ideal for applications such as laser systems, spectroscopy, and imaging.

The lens's geometry, including its diameter, thickness, and focal length, make it suitable for a wide range of optical systems. Its double-concave design allows for precise control of light paths, making it a valuable component in many optical applications.
