Luminar 4010 Fiber-Optic AOTF-NIR Spectrometer

In‑Line & At‑Line Performance

The Brimrose Luminar 4010 AOTF-NIR Spectrometer is designed and built for in-line or at-line measurement using a probe or flow cell together with fiber optics in a production facility.

The 4010 has a stainless-steel housing. The fiber-optic configuration uses a fiber-optic cable to transmit the light from the spectrometer to a probe or flow cell that is mounted in position. The light returns through the fiber from the attachments for analysis. The length of the fiber-optic cable can be up to 300 m with almost no signal degradation.

Key Measurement Capabilities

The Luminar 4010 delivers fast, real‑time NIR measurements that support three major process operations, including reaction monitoring, extraction monitoring, and in‑line analysis.
Key parameters measured include:

***Brimrose Luminar 4010 AOTF-NIR Spectrometer and High Pressure Flow Cell for Monitoring THC Extraction Process***

Reaction Monitoring: Real‑time control of mixing or blending reactions, Hydrogenation progress, Tracking consistent reaction conditions across production runs
Extraction Monitoring: Tracking THC concentration in the cannabis plant, Measuring menthol concentration in cough drops (per NIR application report)
In-line Analysis: Measuring moisture, Checking blend uniformity, Assessing fat, protein, or oil content
