Diamond Turned Aspherical Lenses for LiDAR.

Looking for a way to make your system more compact? Worried about spherical aberrations and other optical aberrations such as astigmatism? Then look no further. Knight Optical presents to you their Diamond Turned Aspheric range.

These diffraction limited aspheric lenses are typically used in LiDAR systems. Wind LiDAR systems in particular when incorporating such aspheric lenses see gains in sensitivity and resolution in wind detection. Additionally Knight Optical aspheric lenses are incorporated into systems to reduce the number of components thus reducing build costs.

Knight Optical’s diamond turned aspheric lenses for wind LiDAR systems are coated with a v-coat centred at 1.5-1.56 micron ensuring optimal performance and minimal losses to the system. The lenses can be provided in a range of materials from optical glasses such as BK7 and UVFS to more exotic materials from the Schott, Hoya, Ohara and CDGM catalogue.

Typical specs:

Material: UV fused silica, N-BK7, Germanium, ZnSe, Caf2, Silicon, Zinc Selenide (For LWIR)
Diameter: Up to 200mm dia +0, -0.02mm
Thickness: +/- 0.2mm
Flatness: < 1/2 wave over 90% aperture
Surface Quality: < 40-20 scratch/dig
Parallelism: 5 arcmin
Coating: AR/DLC (3-5 micron, 7-14 micron, 10-12 micron)

Our Aspheric lenses are checked for quality in our state-of-the-art Metrology laboratory using equipment from Trioptics, Varian and Starret allowing us to work to the highest QA standards and meet the tolerance specifications on these precision components.
