112-1223E 25.4 mm Dia. x -300 mm FL; Uncoated; Plano-Concave Lens
The 112-1223E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -300 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties.
The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 4 mm, while the center thickness is 3.4 mm. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a concave surface on the other.
The lens is made from UVFS MAL-1965, a material with a refractive index suitable for use in the ultraviolet region of the spectrum, specifically at a wavelength of 355 nm. This makes the lens suitable for use in applications that require ultraviolet light, such as certain types of scientific research or industrial processes.
