PROGAZE spectrometer components STP
The PROGAZE STP (Spot Transmission Polychromator) was developed for integration into process spectroscopy systems.
The modules are characterized by high sensitivity during fast measurements, a diffraction-limited optical design, precision-manufactured optical and mechanical components, and high resistance to ambient temperature fluctuations (including through TEC-stabilized detectors) and vibrations. Furthermore, reproducible manufacturing processes ensure consistently high quality. This allows the developed models and databases to be easily transferred to various spectrometer modules within the same series. At the same time, consistent measurement performance and high comparability of measurement results across multiple systems are ensured.
The PROGAZE STP modules can either be used directly (“out of the box”) or customized to meet specific requirements (e.g., spectral range, optical resolution, or optical throughput).
Special features
- High precision in wavelength accuracy
- A precisely specified and reproducible spectral range with exactly defined start and end wavelengths
- Signal-optimized spectral range, even at the edges
- High signal-to-noise ratio and sensitivity
- Very low stray light
- Uniform optical resolution at the theoretical limit
