Description

The Long Working Distance Objective Lens 10X, Working Distance 34 mm, VIS/NIR is designed for precision imaging, laser processing, and optical inspection tasks that require both high magnification and generous clearance between the lens and the sample. With 10X magnification, infinity-corrected optics, and a long 34 mm working distance, this objective is well suited for setups where access to the sample, tooling, fixtures, or scanning hardware is important. It supports visible and near-infrared operation, making it a practical choice for systems that combine coaxial observation with laser-based processing, alignment, or measurement.

This type of objective lens is particularly valuable in industrial microscopy, semiconductor and electronics inspection, laser micromachining, materials analysis, and research environments where users need stable imaging performance without placing the objective too close to the target. The long working distance helps reduce collision risk and leaves more room for sample handling, protective windows, or process hardware, while the infinity-corrected design simplifies integration into advanced optical systems that use tube lenses, beam splitters, filters, cameras, or illumination modules. For OEM instrument builders and laser system integrators, it offers a strong balance of magnification, optical flexibility, and mechanical clearance.

The long working distance objective lens infinity correction function and par focal length 95mm can be used for a laser system and coaxial observation. The objective will allow user to focus a VIS/NIR laser or microscopic observation of objects from a distance.

Frequently Asked Questions

What is the main advantage of a 10X long working distance objective lens with a 34 mm working distance?
The main advantage is that it combines useful 10X magnification with a large gap between the lens and the sample. A 34 mm working distance gives more physical clearance for sample holders, moving stages, laser processing heads, protective windows, and uneven workpieces. This makes the lens especially useful in industrial inspection, laser machining, and metrology applications where a standard microscope objective may sit too close to the target.
Can this VIS/NIR objective lens be used for both imaging and laser processing applications?
Yes, a VIS/NIR long working distance objective lens can be used in systems that need both observation and laser beam delivery. In many optical setups, visible light is used for alignment, monitoring, or imaging, while near-infrared wavelengths are used for processing, measurement, or illumination. A lens designed for visible and near-infrared performance helps support these combined functions more effectively within the same optical path.
Why is an infinity-corrected objective beneficial in an optical system?
An infinity-corrected objective creates a collimated beam between the objective and the tube lens, which makes it easier to insert additional optical components into the system. This is beneficial in laser processing and machine vision setups because beam splitters, filters, dichroic mirrors, cameras, scanners, and other modules can be integrated with greater flexibility. It is a common choice for modern microscope platforms and custom optical assemblies that require modular system design.
What applications are well suited for a 10X VIS/NIR long working distance objective lens?
This type of objective lens is well suited for laser micromachining, semiconductor inspection, electronics manufacturing, wafer analysis, surface inspection, materials research, biomedical imaging, and precision alignment tasks. It is particularly useful where the sample cannot be placed very close to the objective or where extra space is needed for tooling, motion systems, or process monitoring components.
How is a long working distance objective different from a standard microscope objective?
A long working distance objective is designed to maintain focus at a greater distance from the sample than a conventional microscope objective. This added clearance can make a major difference in industrial and laser-based environments, where access around the sample is often limited by fixtures, probes, scanners, or processing hardware. While standard objectives may be optimized for compact microscope observation, long working distance objectives are often preferred for integration into engineering, automation, and photonics systems that require more mechanical flexibility.
