Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. We provide a range of custom aspheric lenses manufactured to your compete custom specification.
Custom precision grade aspheric lenses: Custom precision grade aspheric lenses provide excellent performance over the NIR and VIS spectrums. Our custom range of precision aspheric lenses can be provided uncoated and single-layer AR coated to improve transmission as high as 98% at the desired wavelength. Custom AR coatings can be offered to meet your wavelength application.
Custom plastic aspheric Lenses: Custom plastic aspheric lenses are relatively cheap as they are mass-produced, moulded or pressed, plastic. The surface quality of our custom plastic aspheric lenses is worse than most conventionally polished lenses. Some of these custom plastic aspherics have moulded flanges for ease of assembly. We can provide custom plastic aspheric lenses at competitive prices with very low tooling charges.
Custom fire-polished aspheric lenses: We provide a full range of both custom thermally toughened aspheric lenses and custom un-toughened fire polished aspheric lenses. We also have a huge tooling inventory available for custom aspheric lenses with “no tooling charges” however if you require a custom aspheric lens to your specification we can provide with minimum tooling costs.
Custom aspheric lens sets: We also provide custom aspheric lens sets at reduced costs compared to individually priced lenses. These are ideal for laboratory and design use.
Custom diamond turned aspheric lenses: A range of custom diamond turned aspheric lenses in a range of infra-red materials is also available custom made to your specific requirement.
Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high-quality standards.
