SLB-30-250NM 30.0 mm Dia. x -250.0 mm FL; Coated; Plano-Concave Lens 400-700nm

The SLB-30-250NM is a Plano-Concave Spherical Lens, 30.0 mm in diameter, with a focal length of -250.0 mm, specifically designed for use within the wavelength range of 400-700nm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry.

The lens is crafted from the high-quality material n-bk7 schott, a borosilicate glass known for its excellent optical properties. The lens features a planar front surface and a concave back surface, with a thickness of 2.9mm at the edge and 2mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.

The lens is coated with an Opt M coating on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating helps to reduce reflection and increase transmission, thereby improving the overall efficiency and quality of the optical system in which the lens is used.

The lens is currently in stock and available for immediate purchase. For more detailed information, including pricing and delivery times, please refer to the vendor's website using the provided weblink.
