Visible and NIR laser processing objective lenses are designed for high-precision laser machining, laser micromachining, semiconductor processing, and advanced optical inspection applications requiring exceptional focusing performance across visible and near-infrared wavelengths.

These infinity-corrected objective lenses combine high numerical aperture (NA), long working distance, and advanced aberration correction to support femtosecond lasers, Nd:YAG lasers, and other precision laser processing systems. Optimized for coaxial imaging and laser beam delivery, the objectives enable accurate laser focusing and real-time observation of the processing area during cutting, drilling, welding, marking, and microfabrication operations.

The objective lenses are ideal for laser processing systems operating at visible and NIR wavelengths, including 532 nm and 1064 nm laser platforms commonly used in industrial manufacturing, semiconductor inspection, biomedical imaging, materials research, and precision optical metrology.

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).

Benefits of Infinity-Corrected Objective Lenses in Laser Processing

Infinity-corrected objective lenses project collimated light between the objective and tube lens, allowing additional optical components such as filters, beam splitters, scanners, and imaging systems to be integrated without significantly affecting image quality.

In laser processing applications, infinity-corrected optics provide greater system flexibility, improved aberration correction, and easier integration of coaxial imaging and beam delivery components. This architecture is widely used in advanced laser micromachining, semiconductor inspection, and optical metrology systems.
