Precision Polished Aspheric Lens
Chenyu Optics is a precision aspheric lens manufacturer and supplier supporting custom polished aspheric lenses for imaging, laser and optical systems. Each component is reviewed against the customer drawing, including material, diameter, center thickness, radius, conic constant, aspheric departure, surface figure, slope error, centration, clear aperture and coating requirements.
Precision Polished Aspheric Lens Overview
Precision polished aspheric lenses are part of the broader Optical Lenses range. Their non-spherical surface profile varies from center to edge and can correct spherical aberration within a single optical element.
Compared with conventional spherical lens shapes, an aspheric profile can replace multiple spherical elements in an optical system, reducing element count, weight and assembly complexity while improving focusing and imaging performance.
For drawing-based designs, see Custom Aspheric Lens. Material-specific options include Fused Silica Aspheric Lens for UV and laser-related requirements and Germanium Aspheric Lens for infrared systems. Prototype and repeat production requirements are reviewed against the specified geometry and inspection criteria.
