Mitutoyo 378-888-6 M Plan Apo NUV HR 50X High resolution objective for bright-field observation in near ultraviolett range

The M Plan Apo NUV HR 50X is a premium plan apochromat objective engineered for bright field inspection and laser applications requiring high resolving performance in the near-ultraviolet range. With wavelength correction from the visible spectrum down to 355 nm (Near-UV), it is ideally suited for advanced inspection and laser process monitoring applications.

As a High Resolution (HR) model, this objective delivers exceptional optical performance with a high numerical aperture of 0.65 and a resolving power of 0.42 µm, ensuring sharp detail and strong contrast at high magnification. Its long 10 mm working distance provides practical clearance while maintaining outstanding image quality.

The infinity-corrected plan apochromat design ensures flat-field imaging and excellent chromatic correction across the extended wavelength range. Compatible with VMU and FS-70 microscope systems, the M Plan Apo NUV HR 50X is an ideal solution for precision inspection and demanding near-UV laser applications.
