SLB-10B-15NIR1 10.0 mm Dia. x -14.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-10B-15NIR1 is a high-quality double-concave lens, boasting a 10.0 mm diameter and a focal length of -14.7 mm. This lens is sourced from OptoSigma, a renowned vendor known for their precision optical components. The lens is made from n-bk7 schott, a material widely used in optical systems due to its excellent optical properties.
The lens features a base shape of a circle, with a thickness of 3.6 mm at the edge and 2 mm at the center. The inner and outer radii are 0, indicating a uniform curvature. The back focal length (BFL) is -15.3 mm, and the effective focal length (EFL) is -14.7 mm. The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range.
This lens is a spherical lens, specifically a biconcave lens, which is characterized by having two concave surfaces. This design is often used in optical systems to diverge light beams, making it suitable for various applications. The lens's double-concave structure and high-quality coating make it an ideal choice for applications that require precise optical control in the near-infrared spectrum.
