The M Plan UV 80X is a high-performance objective lens designed for bright field inspection and laser applications requiring ultraviolet capability. Optimised for both 266 nm (UV) and 550 nm (visible) wavelengths, this objective delivers excellent imaging performance while providing high transmission in the ultraviolet range.
With a long working distance of 10 mm, the lens offers practical clearance at high magnification, making it well suited for precision inspection and UV laser processing observation. Its high-quality plan optical design ensures flat-field imaging and consistent clarity across the field of view.
The infinity-corrected optical system provides reliable integration into compatible microscope platforms, including VMU and FS-70 systems.
