23-861 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=50mm; NA=0.25 Laser V-Coat 1064nm
The 23-861 is a precision laser asphere lens, designed and manufactured by Edmund Optics. This lens boasts a 25mm diameter and a focal length of 50mm, making it suitable for a variety of applications that require high-precision optics. The lens is crafted from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens features a high-quality laser V-coat, specifically designed for use at a wavelength of 1064nm. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The lens has a numerical aperture (NA) of 0.25, which contributes to its high light-gathering capability and resolution.
The lens's geometry is another notable feature. It has a center thickness of 7.2mm and an edge thickness of 3.82mm, providing robustness and durability. The lens's front and back surfaces are aspheric, which helps to minimize spherical aberration and distortion, thereby improving image quality.
