Mechanical edges help solve challenges of mounting optical systems

Mechanical edges help solve challenges of mounting optical systems

A major consideration for optomechanical engineers when designing optical systems for applications like augmented reality (AR), lidar, drones, security systems, and more is mounting the system. Beyond designing for accurate positioning and ensuring that the mount doesn’t change the optical properties in any way, engineers must take into consideration how the optical system will perform in many unpredictable situations—even when dealing with a basic imaging system like a drone camera. Engineers must design to protect the optical system from stress due to things like environmental extremes, shock, and vibrations.

The complexities of mounting freeforms

Using freeform optics is beneficial in several ways.

  • Single optical surface allowing for compound compensation

  • Improved system performance

  • Redistribution of tolerances in the system design

  • Reduces the number of optics

  • Additional aberration correction

However, mounting optical systems is especially challenging when dealing with freeform surfaces for AR, for example, since freeforms can be very complex shapes.

One way to help solve challenges of mounting an optical system is to incorporate mechanical edges into your designs.

Adding a mechanical edge to an optical component in LensMechanix

In order to better mount an optical system, you can add a mechanical edge to designs in LensMechanix. Using the Add Mechanical Edge feature, you can add a mounting edge to an optical component without having to load the file as editable. This feature is useful if the original optical component does not have enough material for mounting. You can do this through the Optics Manager or Command Manager, and add a mounting edge to one or more lenses.

LensMechanix streamlines your workflow

Whether you’re working in SOLIDWORKS or Creo, LensMechanix streamlines optomechanical product design. Load all lenses, mirrors, sources, and detectors from OpticStudio as SOLIDWORKS or Creo parts. No need to use STEP, IGES, or STL files. Design using exact optical geometry, retaining the integrity of the data so you don’t have to go through the hassle of redefining optical geometry or positions. Apply surface finishes to mechanical components to accurately model their scattering properties. Analyze your optomechanical system for changes is spot size, beam clipping, and image contamination caused by mechanical components—and save time and provide clarity to manufacturers by generating ISO 10110 drawings from your imported optical components.
