FAC lenses in D class

Share this on social media:

LIMO recently began focusing solely on the production of D lenses while also further enhancing the performance of the lenses over their earlier models.

"This improvement represents significant progress in terms of quality, as it results in a marked reduction of residual divergence by 25% to 45%, depending on the lens," Dr. Homburg explains. "This is the best standard lens quality currently available on the market." Effective immediately, customers can order D-quality FAC lenses from LIMO with standard coatings for a wide range of wavelengths from 600 to 1600 nm. Thanks to an extremely cost-effective manufacturing process that uses wafer sizes up to 350 x 350 mm², the Dortmund-based optics and laser specialist is able to offer the lenses with D quality, without raising the price.

In addition, LIMO has increased its standard FAC portfolio to 11 microoptics with focal lengths from 0.16 to 1.5 mm (previous lineup: five FAC lenses with focal lengths from 0.29 to 1.5 mm) and significantly improved residual divergences from ±0.45 to ± 3.6 mrad. For the micro-optics with smallest focal lengths, LIMO provides integrated monolithic support surfaces so that users can also easily install lenses with short focal lengths.
