Custom Profilometry Inspection Solutions - Optical Profilometry and OCT Systems from Novacam

Custom solutions

Services

Novacam develops custom interferometric solutions to address particular inspection and imaging needs of specialized applications and OEM markets. Our modular interferometer components offer a superior and cost-effective platform for developing high-performance systems and assemblies. We will collaborate with your application experts to devise the optimal combination of inteferometric (OCT) hardware, non-contact fiber-based sensor probes, and system software.

As needed, Novacam engineers:

  • develop customized optical probes and inspection stations
  • develop inline probe fixtures for production environments
  • adapt Novacam standard interferometer component modules to suit your application
  • help integrate Novacam systems or components with third-party tools
  • write customized software

Examples of solutions and benefits

Novacam has a long history of success in developing custom solutions. Here are some examples:

1) Intra-ocular lens inspection

Intra-ocular lens on mold  -  2D cross-section

Intra-ocular lens on mold - 2D cross-section

Novacam solution:

  • Customized application software determines lens curvature, thickness and smoothness
  • Flexible user interface permits operator control of data gathering at preset co-ordinates

Features and benefits:

  • Fully automated lens characterization
  • Sub-micron precision measurements at operator-set points
  • Lens inspection process sped up more than 10 x
  • Defect detection rate increased to 100%
  • Cost savings by early detection of defects
  • Simplified job training

2) Inner diameter inspection of cylinders (applicable to tubes, bores)

Novacam solution:

  • A customized inspection station helps acquire the inner surface of a cylinder in one continuous motion
  • A single probe is rotated to acquire micron-precision dimensional information of cylinder interior
  • Simultaneous dimensional and surface roughness check

Features and benefits:

  • Inspection time cut in half: dimensional and surface measurements performed in one single step rather than traditionally with two different instruments
  • Small lightweight probes easy to integrate into production processes
  • Non-contact technology improves system reliability and availability

3) Blade airfoil 3D inspection

Four axis inspection station for 3D inspection of machined component

4-axis inspection station for 3D characterization of machined components

Novacam solution:

  • Customized 4-axis inspection station with rotating platform scans blade from all directions
  • Simultaneous acquisition of:
    1. blade dimensions
    2. surface roughness
    3. inside-diameters of miniature cooling air holes created by Electrical Discharge Machining (EDM)

Features and benefits:

  • User-friendly interface for controlling and automating movement sequences
  • Inspection and reporting fully automated
  • Measurement rate 100 x faster than modern CMM rates
  • MicroCam profilometer scans at its maximum speed without any loss of precision. In contrast, CMMs must decrease scan rates for the highest precision.
  • In-process integration possible with TCP/IP-based protocols
