Luminar 3070
BenchTop AOTF-NIR Spectrometer
The Luminar 3070 brings the advantages of AOTF‑NIR technology—typically associated with in‑line or at‑line systems—into an easy-to-use benchtop configuration. The 3070 is also naturally resistant to ambient light, making operation simple and reliable in everyday production or QC environments.
Dry Measurements — rotating‑dish reflectance for powders and granules with almost no preparation; single tablets can also be measured in reflectance. Typical speed is 5–8 seconds per sample
Liquid Measurements — flow‑cell setup where the sample is poured into a funnel, allowing a large, well‑mixed volume and supporting less homogeneous liquids. Speed is 5–8 seconds per sample
Transmission Arm with Detector — suitable for single tablets in transmission as well as seeds
