23-866 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=100mm; NA=0.125 Laser V-Coat 532nm

This is the 23-866 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 100mm and a numerical aperture (NA) of 0.125, making it ideal for high-precision 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 3.85mm at the edge and 6mm 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 532nm, which is designed to enhance the lens's performance in laser applications. This coating provides high transmission at the design wavelength and offers excellent environmental resistance, ensuring the lens maintains its performance over time.

The lens is currently in stock and can be purchased directly from the Edmund Optics website. For more information, please refer to the provided weblink.
