Nikon Presents New Industrial Measuring Microscopes

MM series features improved functionality and usability

Published: Wednesday, May 31, 2023 - 11:58

(Nikon Industrial Metrology Unit: Brighton, MI) -- The Nikon MM series of industrial measuring microscopes has been periodically upgraded since the early 1950s, but never to the extent of the latest, sixth makeover.

The company announced that the MM-400N and MM-800N series measuring microscopes would be available the end of May 2023. Both series have aperture-diaphragm control on the diascopic illuminator, which allows an operator to adjust the aperture to optimize contrast and resolution. It’s also possible to set the lighting conditions for measuring cylindrical products.

The newly developed diascopic LED illuminator has both white and green light sources, allowing the operator to change easily from one color to the other by pressing a switch on the front of the microscope without having to insert or remove a filter. Furthermore, by integrating the diascopic illuminator into the main body of the measuring microscope, the depth of the instrument has been shortened by 30 mm, reducing its installation footprint.

As part of the makeover, Nikon has modernized the appearance of the measuring microscopes, which sport the company’s clean, new white-and-black livery. Power consumption has been reduced by 10 percent compared to the former MM-400/MM-800 series models. The manufacturer provides environmentally friendly products and complies with the RoHS Directive and other laws and regulations.

Many component parts are common to the new and previous series models, including the measurement stage, objective lenses, and optical accessories, which a user can continue to use for simple, accurate, and highly reproducible measurement applications:
• Calculated based on Nikon evaluation values
• Based on Nikon standards in consideration of domestic and foreign laws and regulations
