Luminar 4090

Blending AOTF-NIR Spectrometer

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 designed for blend‑uniformity measurements, with more applications planned in the future. It mounts easily to blenders, making it simple to move from one blender to another. The 4090 ensures precise blending time, giving manufacturers full control of their process.

Proper blending is essential to ensure each batch of a drug product is uniform and safe. It is important that the Active Pharmaceutical Ingredient (API), excipients, and lubricants in each batch must be evenly mixed to maintain product quality and performance. Poor blending can affect how the final product works in the body and may pose risks to the consumer. The 4090 helps manufacturers achieve the consistent, uniform blends needed for reliable pharmaceutical production.
