The spectrometer - Basis for a good measurement system
Optical spectrometers analyze the spectral characteristics of light radiation. Adding optical probes and absolute calibration turns this type of measurement system into a spectroradiometer. Since software is used to calculate all radiometric, photometric and colorimetric quantities from spectral data, the quality and precision of the spectrometer is extremely important. This is why Instrument Systems is dedicating most of its research and development work to this field in order to be positioned at the leading edge of technology.
A diffraction grating forms the core of an optical spectrometer. This splits the light radiation being analyzed into its spectral components and projects the spatially split elements onto a detector. Optical spectrometers are manufactured by Instrument Systems in two different designs:
- Array Spectrometers with fixed diffraction grating and a detector array
- Scanning Spectrometers with a single detector and a rotating diffraction grating
Overview of the individual spectrometer models
Model | Type | Area of application | Features |
|---|---|---|---|
CCD Array | Low-cost entry-level model | Power supply through USB interface; dark current measurement and change in density filters are performed manually | |
CCD Array | Turnkey MAS 40 for LED measurements | Adapters for luminous intensity, luminous flux and spatial radiation pattern are flange-mounted directly | |
CCD Array | Benchmarking in industry | Different models from 200-2150 nm; Dark-current shutter and density filter wheel are integrated; high level of accuracy and extremely robust | |
Scanning | High-end, flexible and universal | Very high dynamic measuring range and spectral resolution; spectral range max. 200-5000 nm in one unit; |
