SLB-10B-30NIR1 10.0 mm Dia. x -29.7 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-10B-30NIR1 is a high-quality double-concave lens, boasting a 10.0 mm diameter and a focal length of -29.7 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 2.8 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 -30.3 mm, which is slightly shorter than the effective focal length (EFL), a characteristic of double-concave lenses.
The SLB-10B-30NIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens' performance in the 633-1064nm wavelength range, making it suitable for a wide range of applications, including but not limited to, laser systems, interferometry, and optical imaging.
