23-868 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=75mm; NA=0.16 Laser V-Coat 355nm
This is the 23-868 model from Edmund Optics, a 25mm diameter Fused Silica Precision Laser Aspheric Lens, specifically designed for use with a wavelength of 355nm. The lens boasts an effective focal length (EFL) of 75mm and a numerical aperture (NA) of 0.16, making it ideal for high-precision laser applications.
The lens features a unique aspheric design, which is characterized by its non-spherical surface. This design helps to minimize spherical aberration, a common issue in optical systems, thereby improving the overall image quality. The base shape of the lens is circular, and it has a thickness of 3.78mm at the edge and 5.5mm at the center.
The lens is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. This makes the lens suitable for use in harsh environments and ensures a long service life.
The lens is coated with Edmund Optics' Laser V-Coat 355, a proprietary coating that is specifically designed to enhance the lens' performance in laser applications. This coating reduces reflection and increases transmission, thereby improving the efficiency of the optical system.
The lens is currently in stock and is available for immediate shipping. For more information, please refer to the weblink provided.
