Cylindrical Aspheric Lens
Cylindrical Aspheric Lens
Ashley-Tech manufactures high precison aspheric lens, the accuracy can be 0.5-10um.We professionally make complicated optical system, from design, manufacture to assambly. Material range from optical glass to infrared glass with Traditioanl polish and CNC polish. High Precison aspheric lens mainly used for Thermal image
Parameter
Our cylindrical aspheric lenses (acylinders) are precision optical components designed to focus or shape light along a single axis while minimizing cylindrical aberrations. Engineered for OEMs, integrators, and system designers, these lenses are ideal for laser line generation, diode beam shaping, line-scan imaging, and precision illumination. Available in optical glass and infrared materials, they feature tight PV tolerances (0.5–10 µm), high surface quality (10‑5), and mechanical precision for seamless integration into your optical systems.
