This infinity-corrected, flat-field apochromatic objective lens is designed for laser processing applications, including YAG fundamental wavelength and femtosecond lasers. The optical design minimizes aberrations across the visible spectrum, enabling high-quality coaxial observation of the processing surface during laser machining through the objective lens.

With a working distance of up to 10 mm and excellent flat-field correction, the lens delivers uniform processing line widths and sharp, natural imaging across the entire field of view. A replaceable protective glass element helps shield the objective lens from debris, splashes, and scattered particles generated during laser processing.

The objective lens is also compatible with visible pulsed lasers such as 532 nm sources. The laser damage threshold is:

0.1 J/cm² at 532 nm

0.2 J/cm² at 1064 nm

(measured at a pulse width of 10 ns and repetition rate of 20 Hz).
