Important notes
- Beam edges are not a substitute for a photometric distribution or point-by-point calculation.
- Australian standards may inform project-specific boundaries; this checker does not declare compliance.
Formulas
- \(\displaystyle \Delta = D - S\)
- \(\displaystyle R = \max(0,\Delta)/D\)
- Overlap is a geometric comparison and is not equivalent to illuminance uniformity.
Compare fixture spacing with beam diameter at a target plane.
Beam Overlap Checker is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
