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.
