Engineering experience
03Custom instruments + optics
Custom optical systems across imaging, projection, and lasers
PAO engineering leadership experience designing, tolerancing, testing, and transferring one-off and low-volume optical systems where catalog assemblies were not sufficient.
Attribution boundary
This record describes work performed by PAO engineering leadership in a prior role. It is not a PAO customer case study and does not claim a prior employer's commercial or product-performance results.
01Program context
A system problem, not an isolated optical component.
Custom optical programs often begin with an application requirement that does not map cleanly to a standard lens. The engineering task is to convert that requirement into a prescription, mechanical interfaces, realistic tolerances, a fabrication route, and a test method that can prove the assembled system.
Engineering leadership role
In a prior senior optical-engineering role, PAO engineering leadership worked across high-numerical-aperture microscope objectives, fisheye projection optics, femtosecond-laser optics, and integrated inspection systems, with responsibility spanning design, tolerancing, supplier communication, and test.
02System frame
The interfaces that had to work together.
Prescription
Optical form, materials, stops, aberration balance, and sensitivity
Hardware
Fabrication, coatings, mounts, datums, assembly, and alignment
Evidence
Metrology, image tests, acceptance limits, and model-to-test comparison
03Engineering scope
Responsibilities that transfer to new development work.
First-order architecture and detailed lens design
Sensitivity, tolerance, and manufacturability analysis
Materials, coatings, fabrication, and supplier interfaces
Optomechanical packaging and alignment definition
Metrology, acceptance testing, and fault isolation
04Engineering decisions
Where system judgment mattered.
Make the requirement measurable
A custom lens specification should connect application performance to measurable optical and mechanical acceptance criteria before the design is optimized.
Choose tolerances with the process
Surface form, centration, spacing, material, coating, and alignment limits should reflect available fabrication and metrology, not an idealized drawing alone.
Close the model-to-hardware loop
Assembly data and measured performance should be compared with tolerance predictions so the team can distinguish a part issue, an alignment issue, and a model assumption.
05Engineering outputs
Work products, stated without invented metrics.
Optical prescriptions and performance budgets
Tolerance analyses and supplier-ready drawings
Material, coating, and fabrication recommendations
Alignment concepts and optomechanical interfaces
Metrology and assembled-system test plans
06Transferable lessons
What this experience changes in the next program.
Metrology feasibility should be reviewed before a tolerance is placed on a drawing.
Low-volume custom optics still need configuration control if the first successful build is expected to be repeated.
System acceptance often catches interface errors that component reports cannot reveal.
07Evidence + limits
What supports this record, and what it does not claim.
Supporting records are available during technical qualification. Documented scope is labeled separately, and publication limits are retained so the record remains credible without exposing personal identity or confidential details.
The system categories and engineering disciplines are drawn from verified professional records. Customer identities and program quantities are withheld.
Named customers, confidential designs, precise specifications, quantities, and performance results are intentionally omitted pending separate approval.
