49-588 15mm Dia. UVFS Aspheric Lens; EFL=20mm; NA=0.38 VIS 425-675nm

The 49-588 is a high-performance aspheric lens, boasting a 15mm diameter and a numerical aperture (NA) of 0.38. This lens is designed for use in the visible light spectrum, specifically between 425 and 675nm.

The lens is crafted from UVFS (Ultra-Violet Fused Silica), a material known for its exceptional transparency in the UV and visible regions of the spectrum. This makes the 49-588 an ideal choice for applications that require high-quality imaging or light transmission in these wavelengths.

The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality, with sharper focus and less distortion. The lens also features a high EFL (Effective Focal Length) of 20mm, which contributes to its excellent optical performance.

The 49-588 is coated with a VIS coating (425-675nm), which further enhances its light transmission capabilities. This coating helps to reduce surface reflections, thereby increasing the amount of light that passes through the lens.

The lens is 2.68mm thick at the edge and 6mm thick at the center. It has a front diameter of 0mm and a back focal length of 15.89mm. The lens's geometry is defined by its inner and outer radii, both of which are 0mm, and its conic constant (k1), which is -2.659391.
