LAQ0405 - Precision grade aspheric lenses AR coated
Description
Traditionally lens surfaces have been sections of a sphere. For many applications this leaves spherical aberration as the dominant defect of any image so created. Aspheric lenses are used to correct these image defects. One solution to this is to have one or both surfaces, departing from the spherical shape. Aspheric lenses can be very effective, focussing or collimating laser beams. Aspheric lenses are polished to a good surface finish but the surface is not spherical and shaped to reduce the aberrations from a single on axis point.
These precision grade aspheric lenses will provide excellent performance over the visible spectrum and NIR applications. The glass aspheric lenses are coated with a single-layer AR coating on high index flint glass achieving high transmission of 98% at the stated wavelength (Typical V coating designed for 550nm).

Frequently Asked Questions
Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. Aspheric lenses have a non-spherical surface that allows a single component to effectively focus or collimate even highly divergent emissions.
Aspheric lenses can potentially replace a multi-lens system with a single aspheric lens, reducing the number of components required. They can also effectively correct spherical aberration and collimate light.
Aspheric lenses may be AR coated for UV/VIS/NIR applications. Special AR coatings are also available on stock lenses.
Custom aspheric lenses are available in a range of sizes from 3mm to 200mm+ in diameter.
Aspheric lenses are used to correct spherical aberration in lasers and imaging.
