Holding alignment under load
Mounts and structures must keep elements positioned under gravity, thermal, vibration, and shock.

OPTOMECHANICAL / MOUNTS / ALIGNMENT
Optomechanical design that holds optical performance in the real world.
Palo Alto Optics provides optomechanical design and engineering: the mounts, structures, athermalization, and alignment strategy that keep an optical design performing under temperature, vibration, shock, and assembly. Great optics fail without the mechanics to hold them.

Optomechanical engineering, mount and structure design, athermalization, tolerancing, and alignment for imaging, sensing, and laser systems.
01Engineering reality
A design is only as good as the structure that holds it in place.
Nominal optical performance assumes every element sits exactly where the model puts it. Gravity, thermal expansion, mounting stress, vibration, and assembly variation move elements, and the optomechanical design determines how much performance survives.
Athermalization
Material and dimension choices must keep focus and alignment across the temperature range.
Practical assembly and alignment
The design must be buildable and alignable with realistic tolerances, fixtures, and adjustments.
02Project fit
Contact PAO when optical performance depends on mounts, datums, thermal behavior, alignment, or environmental stability.
The best engagements start with optical sensitivity, package, loads, assembly method, and acceptance conditions rather than treating the mount as an isolated CAD task.
Optics and mechanics are disconnected
An optical model exists, but mount loads, datums, tolerances, access, service, and assembly sequence are not tied to performance.
Environment drives performance
Temperature, gravity, vibration, shock, pressure, or transport can move focus, boresight, wavefront, or calibration.
A build will not align or repeat
The team needs compensators, fixtures, reference surfaces, procedures, and acceptance tests suppliers can execute.
ENGINEERING DECISION TABLE
Inputs that change the architecture, acceptance method, and program risk.
| Input condition | Key metric | Design choice | Risk if unresolved |
|---|---|---|---|
| Optical sensitivities and compensators | Focus, decenter, tilt, boresight, wavefront | Datum architecture, retention, adjustment, assembly order | Mechanical tolerances consume the optical performance budget. |
| Thermal environment | Focus shift, line-of-sight drift, stress, clearance | Materials, geometry, flexures, passive athermalization | A room-temperature assembly fails across operating temperature. |
| Vibration, shock, and gravity | Modal response, displacement, preload retention | Stiffness, damping, support, fasteners, adhesives | Alignment shifts or components are overstressed in service. |
| Assembly and service process | Alignment time, repeatability, yield, recalibration | Fixtures, fiducials, compensators, torque and bond controls | A successful engineering unit cannot be built repeatedly. |

07Qualification questions
Questions engineering teams ask before engaging.
01What is optomechanical design?
Optomechanical design is the engineering of the mounts, structures, and alignment that hold optical elements in position so an optical system performs under gravity, temperature, vibration, and assembly variation. It is what turns a lens prescription into working hardware.
02Do you design athermalized optical assemblies?
Yes. PAO designs passively athermalized assemblies, selecting materials and dimensions so focus and alignment hold across the operating temperature range.
03Can you ruggedize an existing optical assembly?
Yes. PAO can redesign mounts, structures, and alignment for an existing optical system to survive vibration, shock, and thermal environments.
