ADMESY Colorimeters & Spectrometers for the AV‑Market

Best practice

• ✅ Spectrometer + colorimeter is the gold standard: use Hera‑01 20 mm to create the display‑specific matrix, then rely on a high‑speed colorimeter (PCM2-series or Prometheus) for rapid‑speed measurements, flicker, and response work.
• 🖥️ For TVs/monitors, pick the largest optics available (Prometheus/PCM2X 27 mm; Hera 20 mm) to average pixel structure and subpixel layouts, and stabilising dark‑level readings.
• 🌈 For narrow‑band primaries (QD‑LCD, RGB laser), always build a display‑specific matrix from Hera before production measurements.
• 🎥 Projectors: measure reflected from the screen with the same instruments. Diffuser (in‑beam) options are available, but choose thoughtfully; specialised screens can skew direct‑beam vs on‑screen results.

Laboratory / R&D use: PCM2X‑270 vs PCM2X‑271 — key differences

• Luminance (Y) range: 270 ~ 0.00005–40 000 cd/m² · 271 ~ 0.000025–12 000 cd/m²
• Chromaticity (x,y) range: 270 ~ 0.0005–40 000 cd/m² · 271 ~ 0.00025–12 000 cd/m²
• Acceptance angle: 270 uses a ±3° lens (tighter to suppress stray light with small patches or displays) · 271 uses a ±5° wide lens (great on TVs/monitors and projectors)
• Shared platform: same PCM2X electronics (dual‑amp), identical SCPI/USBTMC control and waveform streaming up to 60k samples/second (vs. 600k samples/second internally for equal performance at all gain settings)

Rule of thumb: choose 271 for TV/post‑grade work prioritising deep‑black speed · choose 270 when you need the higher top‑end or a tighter field (e.g., LED walls).

HDR, speed & dark‑level behaviour

For HDR response and black‑level work, the colorimeter does the heavy lifting. Prometheus already established the benchmark for fast dark‑level readings, and PCM2 / PCM2X devices extend the low‑light reach further with its dual‑amp design. High quality optical filters and profilation with the Hera enable accurate color measurements, even with narrow bandwidth primaries.

Ready for Display Calibration & Lab use for testing modern display parameters

Devices listed here are ideal for the AV-/Calibration market as they come in kits with tripod mount and lens tube. They are already implemented in Calibration and Testing solutions like CalMan and ColourSpace.

The light measurement devices (LMDs) listed here speak standard SCPI over USBTMC (and Ethernet/RS‑232 where applicable).

Further integrations are ongoing, straightforward and easy with NI VISA libary, LabVIEW, C/C++, Python, Visual Studio. Windows, Linux and MAC OSX compatible.

Projectors & diffuser options

For projection, we normally suggest to measure reflected from the screen using the same kits (27 mm colorimeter; 20 mm spectrometer). Diffuser (in‑beam) versions can be supplied when you must characterise the beam itself, but choose this wisely: modern projectors and specialised screens can behave differently on‑screen than the beam suggests.

Proudly used by FF Pictures

In our own InnoPQ display lab as well as for calibration work in the post-production, AV-Installation and home theater market, we proudly use the best and latest devices from ADMESY to keep up even with the most demanding needs in HDR and WCG display tests and calibrations.
