All-in-One Display Measurements with the Prometheus Spectrometer

Admesy’s Prometheus Viewfinder Spectrometer is a brand-new flagship for utmost display measurements. Admesy’s spectroradiometer with a combined viewfinder is the true multipurpose display measurement solution.

The electronic viewfinder enables rapid and accurate alignment of the 1 mm to 1.5 mm measurement spot with the close-up lens. Depending on the Neo high-end spectrometer, the optical performance fulfills the highest expectations. A combined flicker sensor completesthe entire package. Similar to all Admesy series, Prometheus is sturdy for 24/7 use and simple to combine in production surroundings.

Electronic Viewfinder

The combined electronic viewfinder makes use of the fixed Pritchard-Optics. The consecutive camera picture enables simple and rapid alignment of the measurement spot. It is also optional for the camera pictures to be stored with the measurement for clear documentation.

1 mm to 1.45 mm Measurement Spot

With the availability of the fixed close-up lens, the measurement spot is tailored to quantify the best details between 1 mm and 1.45 mm. By selecting a corresponding measurement distance, it is possible to achieve different spot sizes. The brief measurement distance is 57 mm and the longest is 71 mm.

Admesy’s Prometheus Viewfinder Spectrometer is a brand-new flagship for utmost display measurements. The spectroradiometer from Admesy comes with a combined viewfinder and is the true all-in-one display measurement solution.

The electronic viewfinder enables rapid and accurate alignment of the 1° measurement spot with the standard lens or the 1 mm to 1.5 mm measurement spot with the macro lens. The optical performance fulfills the greatest expectations based on the Neo high-end spectrometer.

An integrated flicker sensor finishes the whole package. Like all Admesy series, Prometheus is sturdy for 24/7 use and is simple to combine in production surroundings.

Electronic Viewfinder

The combined electronic viewfinder makes use of the established Pritchard-Optics. The resulting camera picture enables simple and rapid alignment of the measurement spot. The camera picture can be saved with the measurement for unmistakable documentation.
