Spectrophotometers are more commonly used today by manufacturers to ensure first-time color quality and lot-to-lot consistency of products on the factory floor. These instruments, as a result, must meet some very demanding conditions, including uneven lighting, high humidity levels, varying temperatures, and shock and vibration.

A feature article in the October issue of Photonics Tech Briefs (PTB) contributed by X-Rite (Grand Rapids, MI) explains how spectrophotometer technology has advanced to meet these factory-floor conditions. Robust, inline, LED-based spectrophotometers can measure colors accurately, quickly, and in harsh environments. These new instruments are also about one-fifth the cost of spectrophotometers based on older technologies.
