Aspheric Lenses
High-Precision Aspheric Optics for Enhanced Imaging and Compact Optical Design
MLPhotonic specialises in the manufacturing of aspheric lenses.
These lenses are widely used in various optical systems and allow for improved performance with a reduced number of optical elements.
Our aspheric lenses are made from glass and quartz materials (typically using materials from SCHOTT, OHARA, or CDGM). In addition, we offer aspheric lenses of IR materials (such as ZnS, ZnSe, Ge, Si) and metal mirrors.
Classifications:
- Single-sided aspheric lenses
- Bi-aspheric lenses
- Off-axis aspheric lenses
For glass and quartz materials:
The possible diameter range is 10mm to 300mm, with a minimum concave radius of 50mm.
For IR materials:
The possible diameter range is 2mm to 400mm.
Metrology & Quality Assurance:
ML Photonic offers optical metrology, including surface profilometry and interferometry to verify specifications are achieved for fabricated optics. We perform inspections on all optical components during the manufacturing process and provide inspection reports.
