NanoCam HD

Small, non-contact optical profiler for vibration-immune roughness measurement

The NanoCam™ HD dynamic profiler measures surface roughness on small to meter-scale coated and uncoated optics, as well as precision metals, plastics, and other polished specular surfaces.

With unmatched flexibility, the light weight NanoCam HD can be easily positioned on large parts by hand, or mounted on a gantry or robotic arm to measure with sub-angstrom level repeatability and precision.

The NanoCam HD can measure finish:

  • anywhere on a large surface
  • inside production stations and polishing equipment
  • multiple parts arrayed on a table
  • directly on large optics and mirror segments.

Portability and on-machine capability significantly reduce the handling and transportation of large optics, increases throughput and dramatically reduces the risk of damage to expensive, critical optics.

The NanoCam HD replaces the NanoCam Sq.

The NanoCam HD surface roughness profiler utilizes Dynamic Interferometry®, with a high-speed optical sensor that measures thousands of times faster than traditional profilers. Because acquisition time is so short, the NanoCam HD can measure despite vibration, making it possible to mount the instrument on a gantry or robot end effector as well as inside of a polishing station to measure polishing quality.

Applications for NanoCam HD optical profilers include surface roughness of small and large coated/uncoated optics, on-machine surface roughness metrology, and process control for polishing operations, including measuring superpolish.

 New autofocus capability allows for faster, more consistent measurements requiring fewer manual adjustments. Measure parts with reflectivity from 0.5% to 100% without changing reference optics. Single cable, power-over-ethernet operation can be combined with high speed innovative software for data acquisition and analysis in a laptop environment for added portability.

NanoCam HD Dynamic Optical Profilers include 4Sight Focus advanced analysis software. Industry-leading 4Sight Focus software reports ISO 25178 surface roughness parameters (S parameters) and provides extensive 2D and 3D analysis options, data filtering, masking and import/export functions.
