What is Photometry & Radiometry calibration?
Photometry & radiometry calibration determines the error of light and optical-radiation instruments: lux meters, luminance meters, UV radiometers and optical power meters. Techmaster’s ISO/IEC 17025:2017 lab is traceable to the candela (cd) and lux (lx).
Light and radiation measurement matters in lighting, occupational safety, electronics/optics manufacturing and cleanrooms. A drifting lux meter or UV radiometer can misjudge lighting conditions or UV dose.
Techmaster calibrates photometric/radiometric instruments with reference light sources and detectors that are traceable, ensuring traceability to the SI candela/lux; supporting factory and lab lighting control and optoelectronic lines.

Typical measurement ranges & CMC
The table below lists typical parameters & measurement ranges for this discipline.
| Parameter / Instrument | Typical measurement range | CMC / Measurement uncertainty |
|---|---|---|
| Illuminance | 1 – 100 000 lx | [Verify against scope] |
| Luminance | per instrument range | [Verify against scope] |
| UV irradiance | per instrument range | [Verify against scope] |
| Optical power | nW – W (per detector) | [Verify against scope] |
| Wavelength | per instrument range | [Verify against scope] |
⚠ Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.
Reference standards & traceability
Photometric measurements are traceable to the SI candela (cd) and lux (lx) via certified reference light sources and detectors; UV irradiance/optical power are traceable through calibrated reference detectors.
