According totheoptical systemdesign and optimization and withourPE engineers about 2-month work, the new achromatized telecentric scan lenses for both 532nm and 635nm released.

The newtelecentric lens not only canbeusedfor 532nm green laser marking but also work with visual wavelength for 635nm for illumination. Sothe user canlook at thescreen at the same time forlaser making.

Traditional telecentric f-theta lenses can work only for single laser wavelength, so the position of the visual image will be different with the laser marking, butournew product will solve this.

When the 532nm green laser workingпthe working plane will be illuminated by the 635nm LED. You canget the high resolution image for the spot size using the achromatized telecentric scan lenses, both the twice spot size will be in the limited size of diffraction, which be named airy disk.
