Standard AOTF-NIR Spectrometers
Brimrose’s standard AOTF‑NIR spectrometers provide robust, ready‑to‑deploy solutions for a wide range of industrial process applications. Built on our proven AOTF technology, these NIR spectrometers deliver fast, stable, and repeatable measurements without the need for custom engineering. Designed for in‑line, at‑line, and multi‑purpose use, they offer reliable performance across diverse operating environments while keeping integration simple and cost‑effective.
AOTF-NIR Technology
Brimrose’s Acousto‑Optic Tunable Filter (AOTF) technology is the foundation of our AOTF‑NIR spectrometers, providing fast, stable wavelength selection for reliable measurements. Each model applies this core technology in a configuration optimized for its specific application. This solid‑state design performs well in laboratory, at‑line, and especially in‑line process environments. For a deeper explanation of AOTF operation and its role in AOTF‑NIR spectroscopy, see our full AOTF‑NIR technology overview.
In‑Line / At‑Line AOTF‑NIR Models
Luminar 4010
Fiber-Optic NIR Spectrometer
The Luminar 4010 is designed for continuous, in‑line or at-line measurements in demanding industrial settings. The 4010 is driven by our AOTF‑based NIR technology and uses a fiber‑optic cable to transmit light from the spectrometer to a probe or flow cell. Its compact stainless‑steel housing and remote‑mount design provide durable, stable spectrometer operation.
Luminar 4030
In-Line NIR Spectrometer
The Luminar 4030 is designed for continuous, in‑line analysis in demanding process environments. The 4030 operates in free‑space mode using our AOTF‑based NIR technology to deliver rapid, non‑destructive analysis. Its stainless‑steel enclosure and fixed‑distance mounting allow transmitted light to reflect from the sample for optimal analysis, ensuring consistent, reliable spectrometer performance.
Luminar 5030
Portable NIR Spectrometer
The Luminar 5030 is our most versatile and portable system, offering flexible‑use operation across multiple environments. The 5030 uses our AOTF‑based NIR technology to deliver fast, non‑destructive measurements. It features an aluminum housing and can be used hand‑held, in laboratory setups with a lab stand, or mounted with a mounting plate when stainless steel is not required.
Luminar 3060
Multiplexed NIR Spectrometer
The Luminar 3060 is designed for multiplexed, multi‑point NIR measurements in heavy‑duty industrial environments. Each channel connects to a probe or flow cell via fiber‑optic cable, and the system uses our AOTF‑based NIR technology to multiplex a single spectrometer by rapidly switching the light source from each channel into the detector. This configuration allows all active channels to be sequentially analyzed in less than one minute, providing rapid, non‑destructive analysis across multiple points in a process.
Luminar 7030
In-Line NIR Spectrometer
The Luminar 7030 is designed for continuous monitoring. The system consists of two enclosures: one containing the optics at the product location and a second enclosure housing the electronics, connected by a 1‑meter cable. The spectrometer operates in free‑space mode using our AOTF‑based NIR technology for non‑destructive analysis. The compact enclosures allow the system to be mounted in tight in‑line spaces where the Luminar 4030 may not fit, delivering consistent spectrometer performance in tight installations and harsh industrial conditions.
Luminar 4090
Blender‑Mounted NIR Spectrometer
New Model in Development
We are proud to introduce the Luminar 4090, a new AOTF‑NIR spectrometer currently offered as a customized development within our standard Luminar series. The compact system uses our AOTF‑based NIR technology and is configured for blend‑uniformity measurements, with additional applications planned for future development. It mounts easily to blenders, allowing customers to move the unit from blender to blender. The 4090 ensures precise blending time, giving manufacturers complete control of their process.
