SLB-50.8-150NM 50.8 mm Dia. x -150.0 mm FL; Coated; Plano-Concave Lens 400-700nm

This is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 50.8 mm and a focal length of -150.0 mm. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens's geometry includes a thickness edge of 7.3 mm and a thickness center of 3 mm, making it suitable for applications requiring a thin lens with a deep concave surface.

The lens is coated with an opt m coating on both the front and back surfaces, enhancing its performance in the 400-700nm wavelength range. This coating reduces reflection and increases transmission, making it ideal for use in laser applications or any system where high transmission and low loss are critical.

The lens's base shape is circular, and its shape is spherical, which is a common choice for its ease of manufacturing and versatility. The lens's inner and outer radii are both 0, indicating a straight edge and a flat outer surface.
