OPG ComplIments Your Team

Optical Perspectives Group (OPG) are experts at optical fabrication, testing, assembly and alignment. We excel in alignment of aspheric optics, off-axis designs, and large optics at the prototype stage. OPG can recommend cost effective sources for your optical components and subassemblies. OPG optimizes performance while minimizing your risk.


OPG applies over 40 years experience to optical system fabrication and testing.

OPG complements your team in the following areas:

  • Modeling and tolerancing test set-ups, including error budgets
  • Designing test sets up and writing assembly and test procedures
  • Specifying test equipment and training personnel in its proper use
  • Certifying that individual components meet specification
  • On prototypes, laying out the project through assembly or…
  • Assisting in training production personnel to quickly assume responsibility for system assembly

 Involve OPG at the project design phase to build alignment capability into the system, and avert a crisis in assembly.

OPG maximizes your system performance.

Contact us today to minimize your schedule and performance risk.

Case Studies & Testimonials

  • How small can the PSM be used for centering on a cylindrical axis?

    The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?

    The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.

  • Why is proper alignment so important?

    Here is a case of a very happy customer due to better optics.

    A few days ago an astronomer friend of mine commented that he had gotten the optics of his telescope improved and the improvement reduced the time it took to get data by a factor of 3. For an astronomer this is a dramatic improvement since observing time on large telescopes can cost thousands of dollars an hour.

    My friend did not say how the optics had been improved, but the important point is that better optics, whether due to figure errors, mounting or alignment mean more productive optics. I generally think of better optics as a better product leaving the manufacturing facility without thinking about how much the better optics mean to the productivity of the customer.
