Engineering note / 4 October 2026
Define the optical function
State the wavelength range, imaging or illumination function, available envelope and critical interfaces. Establish whether the discussion begins with a specification or an existing drawing.
Include the mounted assembly
POG documents alignment turning for mounted lenses and optical metrology for system alignment. Mechanical references and centring requirements should be part of the brief when the optical performance depends on an assembled system.
Agree the evidence
Identify the measurements and records required at acceptance. POG lists wavefront, MTF and transmission measurement methods; the suitable method and acceptance values are project-specific.
This note helps prepare a technical brief. Product performance and application suitability require project-specific confirmation.
