Referenzlampen
Referenzlampen are specialised light sources that serve as stable, well‑characterised references for optical measurements, calibration, and quality control in scientific, industrial and consumer applications. Their principal purpose is to provide a reproducible spectral output that can be compared against unknown samples or measurement instruments, thereby enabling accurate determination of quantities such as irradiance, spectral power distribution, colour temperature or photometric performance.
The use of reference lamps dates back to the early 20th century, when the introduction of incandescent
Typical applications include spectrophotometer calibration, colour measurement in printing and manufacturing, illumination level control in photographic
Reference lamps are classified by their emission characteristics, stability, and maintenance requirements. Tungsten‑halogen lamps offer a
Standardised reference lamps are listed in national inventories and are essential for maintaining measurement consistency across
