Reference light sources

Precise calibration made easy with our cost-effective reference light sources

To achieve reliable spectral measurements, not only a good spectrometer is crucial, but also the correction of the sensor's spectral sensitivity and the grating's diffraction efficiency.

Each pixel of a CCD or CMOS sensor reacts differently to light of different wavelengths. Without this correction, measurement results will be distorted, especially in quantitative analyses.

The traditional calibration methods use high-precision, calibrated deuterium or halogen light sources.
Halogen lamps are so-called blackbody lamps and deliver a nearly ideal Planck spectrum at a defined temperature and are considered standard in laboratories. However, such devices are often expensive and complex to operate.

Our solution: inexpensive reference light sources based on a stably regulated halogen lamp.

Through calibration with a high-precision reference light source traceable to the NIST standard, these lamps still achieve excellent spectral accuracy.

The process is two-step:

1. Calibration: The halogen lamp is compared once in-house with the high-precision light source. This allows its spectral emission behavior to be precisely determined.
2. Practical use: The now calibrated lamp serves as an easy-to-use reference for calibrating spectrometers – ideal for schools, universities, or laboratories that value reliable measurements but do not want to use expensive laboratory light sources.

Your advantages:

- Reliable spectral correction of the sensors
- Affordable alternative to official standards
- Easy to use in educational institutions
- Sufficient accuracy for many quantitative spectral analyses

With our reference light sources, you ensure that your spectrometers deliver precise, reproducible, and comparable results.

The power supply for the reference light source supports two different operating modes, which can be selected via a DIP switch.
