The 48-048 12.0mm Dia. x -40 FL is a spherical, uncoated plano-concave lens sourced from Edmund Optics. This lens is designed for use in ultraviolet (UV) applications, making it suitable for a wide range of scientific and industrial uses.
The lens has a diameter of 12.0mm and a base focal length (FL) of -40.0mm, indicating its concave shape. The edge thickness measures 2.91mm, while the center thickness is 2.0mm, providing a slim profile that can be beneficial in various applications. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.
The lens is made from fused silica, a material with a high transmission rate in the UV spectrum, making it ideal for UV applications. The lack of coating on this lens means it is unprotected, so it may be more susceptible to environmental damage. However, this also means that it has a higher transmission rate across the UV spectrum.
The lens is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. However, its UV transmission capabilities make it a versatile option for UV applications.
