Mechanism assessment
An evaluation of the physical mechanisms that can and cannot produce the observed behavior.
About Brooks Photonics
Independent analysis for difficult infrared detector questions.
Electrical, spectral, and noise measurements are reviewed together to separate material limitations, device behavior, and test artifacts.
Purpose
Use the existing data before committing to another process run.
Infrared detector data rarely fails in only one dimension. Resistance, responsivity, spectral cutoff, noise, thermal behavior, contact geometry, and instrumentation can produce similar symptoms.
The review starts with the measurements already available and checks which explanations are consistent with the complete dataset.
Deliverable
What the review includes
Documented evidence
Figures, calculations, assumptions, and confidence limits presented in a concise technical document.
Validation plan
Measurements selected to distinguish the remaining explanations without unnecessary process iterations.
Working method
Methods and assumptions are documented.
Use the complete dataset
Electrical, spectral, thermal, geometric, and test-system constraints are evaluated together.
State assumptions
Unknown quantities, model limits, and inferred parameters are identified rather than hidden.
Prefer discriminating tests
Recommendations focus on measurements that separate competing physical explanations.
