AOTF-NIR Spectrometer (In-line Process)

The Brimrose Luminar 3060 Multiplexer AOTF-NIR Spectrometer is designed for at-line measurement in a production facility with up to 16 active channels. Each channel is connected to a probe or flow cell with fiber-optic cable. A single spectrometer is multiplexed by rapidly switching the light source from each channel into the detector. All 16 channels can be sequentially analyzed in less than 1 minute.

The 3060 can be a cost-effective option when needing multiple test points and not wanting to purchase multiple 4030’s (or another Brimrose AOTF-NIR model). Choosing between a 4030 and 3060 depends upon the number of test points required and the location of each test point due to the length of fiber-optics required to be run.
