Nano-Inspection Lab

Nano-Inspection Lab

All of the products produced at Miltera flow through our state of the art inspection laboratory.  Located in the core of the building and isolated with airlocks, our laboratory is an ISO Class 5 clean room held to a nominal temperature of 20.00°C +/- 0.25°C and 50.0% +/- 5.0% relative humidity.  Particulate is controlled using 2 zones of HEPA filters.  Parts enter the inspection lab through our aclimitization chamber which allows for components to reach inspection temperature before entering the room.  This laboratory is home to our Zeiss Micura CMMZeiss Centermax CMM, and Alicona µCMM.

Alicona Infinite Focus G5 Plus

InfiniteFocus is a highly accurate, fast and flexible optical 3D measurement system. With only one sensor, users verify dimensional accuracy and measure surface roughness of their components. Based on the technology of Focus Variation the range of measurable surfaces is almost unlimited. By means of Vertical Focus Probing, which is an extension of Focus-Variation vertical surfaces are probed laterally as well. Components are traceably measured in high accuracy, with a high vertical resolution and in high repeatability. 


Measurement Principle: non-contact, three dimensional, based on Focus-Variation

Positioning Volume (X, Y, Z):  200 x 200 x 100mm

Flatness Deviation: 1.6 x 1.6mm with 10x objective

Alicona uCMM

The Alicona µCMM is the first purely optical CMM machine used to measure extremely tight tolerances with high accuracy. Combining the advantages of tactile coordinate measuring technology and optical surface measuring technology to measure the dimension, position, shape and roughness of components with only one sensor.


Measurement Principle: non-contact, three dimensional, based on Focus-Variation

Travel Speed of Axes: Up to 100 mm/s

9 Temperature Sensors, 3 Vibration Sensors


Multi Measurement = (0.8 + L/600) μm

Single Measurement = (0.15 + L/50) μm


Zeiss Micura CMM

Our ZEISS MICURA is located in an isolated inspection laboratory with a dedicated HVAC system with 5 temperature averaging sensors maintaining temperature stability of 21ºC +/- 1 º Celsius. 

Additionally a workpiece temperature sensor allows compensation of workpiece temperature variation from ambient.


Accuracy: 0.7 + L/400 μm

Smallest stylus diameter: 0.3mm

Travel: X, Y, Z (500, 500, 500)

Ceramic guideways and a large bearing base minimize susceptibility to external influences

Computer-Aided Accuracy (CAA) - Measuring errors due to dynamically induced inertia effects are automatically compensated for greater accuracy

Zeiss Centermax-1 CMM

Our CenterMax navigator is located in our air-locked, thermally isolated inspection laboratory with 5 temperature averaging sensors maintaining temperature stability of 21 ºC +/- 0.5 ºC. Humidification and dehumidification system maintains humidity levels to 50% RH +/- 5%. Two banks of HEPA filters with low level ducted returns control particulate levels.


Accuracy: 0.7um + L/1000mm

Temperature stability from +15ºC to +40ºC

Pneumatic vibration insulation

Helix scanning

Dynamic stylus calibration
