SLB-10-20NIR1 10.0 mm Dia. x -20.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-10-20NIR1 is a plano-concave lens with a diameter of 10.0 mm and a focal length of -20.0 mm, specifically designed for use in the wavelength range of 633-1064nm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements.

The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The plano-concave geometry of the lens, where one surface is flat and the other is curved, makes it suitable for a variety of applications. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple, straightforward design.

The SLB-10-20NIR1 features a coating of opt ir1 on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in the infrared region of the spectrum, making it ideal for applications such as thermal imaging, spectroscopy, and other infrared-based technologies.

The lens has a thickness of 3.3 mm at the edge and 2.0 mm at the center, providing a robust structure while maintaining a compact form factor. The effective focal length (EFL) of the lens is -20.0 mm, which is the distance from the lens to the point where the light rays converge or diverge. The back focal length (BFL) is -21.3 mm, which is the distance from the back surface of the lens to the point where the light rays converge or diverge.
