| * To further increase maximum scanning depth, a mechanical displacement axis is available. Instrument safety: MicroCam non-contact profilometers are class 1M laser products with < 20 mW of infrared and < 5 mW of in-probe laser pointer. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| This table shows the relationship of lateral resolution (light spot size), focal distance, depth of focus and probe aperture. Depth of focus is the distance on either side of the focal plane where light spot size is v2 (approx 1.42) bigger than the spot size in focus. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Key advantages
- Wide range of materials: plastics, polymers, glass, metal coatings, silicone, adhesives; reflective, transparent, semi-transparent, specular, nonspecular
- Wide range of objects and surfaces: small (several microns wide) to large (no upper limit) objects, stationary or moving, solids and liquids, interiors of bores and tubes, exteriors of cylinders, concave or convex spherical shapes, extremely hot or cold, radioactive
- Non-contact probes work up to 1 m away from surface and more than 1 km from interferometer
- Small-diameter probes reach in to measure insides of bores and small-diameter tubes
- Acquires high-aspect-ratio surface features: channels, grooves, steps, sharp edges, and more
- Continuous, long profile scanning: no area stitching required
- Option of multiplexing probes with single interferometer for simultaneous measurements of several objects
- Easy integration of fiber probes in labs and in process: on XY tables, on multi-axes scanning mechanisms, inside machining centers, above moving webs, etc.
- Rugged probes: inspection possible in hostile environments where humans cannot work
- USB connection for data transfer from interferometer to PC or laptop
Standard MicroCam system includes
- MicroCam-3D interferometer with 4 mm depth range
- 2-axes inspection station with manual elevator and 2-axes motion controller

Fiber-based optical probes
Standard probes
|  Novacam standard and small-diameter probes |
| Custom probes Novacam designs and builds custom probes as needed. These can be: |
- Extra-small, with diameters as small as 0.9 mm
- Rotational
- Extra-long to reach into hard-to-reach spaces
- Combined with galvanometers for efficient area or strip scanning
- Extra rugged for high temperatures and extreme environments
2D Galvo scanner probe
Lab inspection stations
For lab and QA applications:
Probes may be integrated with 3rd party CMMs (coordinate-measuring machines), CNC (computer numerical control) machines, or any robots. Novacam designs and builds custom benchtop fixtures as needed. |  Novacam 2-axes inspection station with manual elevator
|
Inline probe fixtures
Web scanning can be accomplished
- with a single scanning probe moving across the web or
- with multiple stationary probes which are multiplexed by an optical switch.
Novacam designs and builds custom inline fixtures as needed.
Optical switches for use with multiple probes
Optical switches are available for multiplexing up to 8 probes to a single interferometer.
