Description

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 nm0.2 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.

Frequently Asked Questions

What is an infinity-corrected 10X objective lens used for in laser processing?
An infinity-corrected 10X objective lens is used to focus laser beams with high precision while also supporting imaging and inspection within the same optical setup. In laser processing systems, it can be used for micromachining, marking, trimming, semiconductor processing, wafer inspection, and other applications where stable beam delivery and clear observation of the work area are important. The infinity-corrected design also makes it easier to integrate additional optical components such as beam splitters, filters, scanners, and cameras.
What wavelengths are supported by this visible and NIR laser processing objective lens?
This type of laser processing objective lens is designed to work across visible and near-infrared wavelengths, making it suitable for systems that use common laser sources in both spectral regions. Depending on the exact model, it can support visible wavelengths for alignment and imaging as well as near-infrared wavelengths used for material processing, precision machining, and industrial laser applications. This dual-band optimization is especially valuable in systems that combine coaxial viewing with NIR laser delivery.
Why is a 10X objective lens a good choice for laser processing and optical inspection?
A 10X objective lens offers a practical balance between magnification, field of view, working distance, and spot size control. In laser processing, this makes it useful for applications that require precise focusing without sacrificing too much viewing area. It can be a strong option for fine marking, microstructuring, surface treatment, and inspection tasks where operators need both good process visibility and reliable laser beam concentration at the target.
What are the advantages of using an objective lens optimized for both visible and NIR wavelengths?
An objective lens optimized for both visible and NIR wavelengths helps maintain strong optical performance across imaging and laser processing functions in a single system. In practice, this can improve alignment accuracy, reduce the need for separate optical paths, and support coaxial imaging while the laser is operating at a different wavelength from the viewing system. It is particularly useful in advanced laser workstations, research instruments, and automated processing platforms where visible imaging and NIR laser delivery must work together efficiently.
How is a laser processing objective different from a standard microscope objective?
A laser processing objective is typically designed not only for imaging, but also for handling focused laser beam delivery in demanding industrial or scientific environments. Compared with a standard microscope objective, it may offer wavelength optimization for specific laser bands, higher damage tolerance, longer working distance, better compatibility with beam delivery architectures, and optical performance tailored for machining or inspection tasks. This makes it better suited for applications such as laser micromachining, wafer processing, precision drilling, and other photonics-based manufacturing processes.
