Nikon MM-400N/800N Series Measuring Microscopes

Nikon’s lenses offer superior performance with very long working distances, excellent high-contrast, flat-field images and reduced errors due to their telecentric design.

Nikon’s innovative optics enable clear, high-contrast brightfield, darkfield, polarized (POL) and differential interference contrast (DIC) images for precise, accurate measurement of low contrast features.

Six robust stages are available for the MM-800N, ranging from 12” x 8” (300 mm x 200 mm) down to 2” x 2” (50 mm x 50 mm), of which the three smaller stages up to 6″ x 4″ (150 mm x 100 mm) are compatible with the MM-400N.

High precision and repeatability as well as accurate results are guaranteed throughout the long service life of the instruments, supported by an extensive range of optical components and accessories.

The outstanding modular range allows the user to optimize measurement performance by configuring exactly the right accessories to achieve an efficient and effective inspection process.

LED illumination settings, XY-stage coordinates and Z-axis data are transferred to the MM controller and Nikon’s E-Max software on a PC for full data processing and system control.

Projected patterns enable accurate, repeatable focusing for excellent Z-axis measurement. Errors due to depth of focus variations are minimized and multiple operators achieve the same results.

Diascopic LED illuminator now has both white and green light sources and the operator can easily switch the light without inserting or removing filters. Intensity is controlled from the instrument or via PC interface using E-MAX. Without bulb replacement and constant color temperature, (no red shift) accurate, repeatable measurements are enabled.

The microscope has aperture diaphragm control on the diascopic illuminator, which allows an operator to adjust the aperture to optimize both contrast and resolution. It is also possible to set the lighting conditions for measuring cylindrical products.

Extreme capabilities allow for large component dimensions with a maximum of 12"x8" (300mm x 200mm) XY stage travel, 20kgs component mass and 200cm in height above the measuring stage glass for the MM-800N series.

Nikon's DP-E1 unit combines accuracy with ease of use. Teaching and measurement files can be exported by USB stick. Nikon's E-Max software provides measuring support tools via common GUI, processing measurement data and exporting results.

From the complete range, the three largest stages have a rotation function. Achieving precise component alignment over long measuring distances even when measuring samples up to 20kgs, enabling faster and more efficient measuring.
