A calibration-focused comparison for technical buyers and laboratory managers. This page is independent and does not imply manufacturer affiliation.
| Criterion | JETI specbos 2501 | Instrument Systems CAS 140D |
|---|---|---|
| Typical concept | Portable / flexible spectroradiometer | Laboratory array spectroradiometer |
| Common use | Field and laboratory radiance or irradiance work | High-throughput laboratory and production measurement |
| Configuration focus | Telescope, diffuser and accessory setup | Input optics, fibre and system integration |
| Calibration risk | Accessory and geometry mismatch | Range, linearity and integrated-system configuration |
Nominal specifications do not define the calibration programme by themselves. The actual measurand, spectral range, optical accessories, software settings, signal level and intended application must be considered.
LightingLab calibrates instruments from both sides of this comparison. The service recommendation is based on the requested measurement task, not on brand preference.
Choose based on application, speed, optical geometry and integration needs. Calibration should follow the exact configuration rather than the brand name alone.
