Knight Optical’s Moulded Aspheric Lenses for Laser Diode Collimators

25 Mar 2020

Knight Optical’s extensive range of custom-made Moulded Aspheric Lenses meets the demands of the most complex, high-specification projects; including the specific requirements of discerning engineers working on laser diode collimators. 

 Aspheric Lens surfaces are typically employed in laser-based and imaging technologies to correct spherical aberration (in which the converging light from a lens does not have a collective focal point – resulting in a distorted image). 

 While traditional Spherical Lenses cannot collimate light effectively due to the small angles of incidence (AOI) producing spherical aberrations, the non-spherical surface of an Aspheric Lens allows a single component to effectively focus or collimate even highly divergent emissions. By using Aspheric Lenses, engineers eliminate the need for multiple components and potentially cumbersome systems. Aspheric Lenses are particularly prevalent within laser diode-to-fibre coupling applications for this distinct advantage. 

 Here at Knight Optical, we have vast experience of working with engineers on custom-made Aspheric Lenses for laser diode collimator applications. Our knowledgeable team can assist you with tolerance, substrates, optical coatings as well as project-specific shapes and sizes for optimum operability of your application. 

 Typical specs:

Material: Optical Glass or Acrylic 

Overall diameter tolerance: +/-0.2mm

Focal length tolerance: ± <5% 

Surface quality: 

Coating: Optional
