Fused Silica Spherical Lens
Chenyu Optics supplies custom fused silica spherical lenses according to the specified fused silica grade, UV/VIS/NIR wavelength range, diameter, center thickness, radius, focal length, centration, surface requirements, clear aperture and AR coating wavelength. Final material and optical specifications are confirmed against the customer drawing and inspection requirements.
Fused Silica Spherical Lens Overview
Fused Silica Spherical Lenses are spherical optical elements manufactured from a specified fused silica grade selected for the operating wavelength and application environment.
UV, visible and near-infrared suitability depends on material grade, purity, absorption characteristics and coating design. For laser use, wavelength, pulse conditions, beam diameter, energy density and coating requirements must be reviewed rather than inferred from the material name alone.
Chenyu Optics supports drawing-based production with diameter, center thickness, radius, EFL/BFL, centration, surface quality, surface figure, clear aperture and AR coating wavelength specified for prototype or repeat production.
