ProMetric PM-1000 Imaging Photometer & Colorimeter

ProMetric PM-1000 CCD Imaging Photometer & Colorimeter

Affordable spatial luminance, illuminance & colour measurements

The PM-1000 is the affordable, entry-level ProMetric imaging photometer based upon an uncooled, interline transfer-type CCD sensor with 1392 x 1040 pixels. With a dynamic range of 10 bits, the PM-1000 can resolve 1,024 different levels of brightness and colour. The PM-1000 is available as a photometer with a photopic response (model PM-1000-0) or as a colorimeter with a Bayer RGB filter system applied to the CCD sensor (model PM-1000-1).

The PM-1000 stands out for its low cost, making it suitable for cost-sensitive production and R&D applications. It is also our fastest imaging photometer, requires no cooling and has no shutter or moving parts, which eliminates the need for routine servicing. The PM-1000 is best suited to area uniformity measurements of luminaires, displays and backlights, but for use with LEDs, we recommend the PM-1200, PM-1400 or PM-1600 due to their higher colorimetric accuracy.

Ordering Information

Each PM-1000 system comprises the ProMetric photometer or colorimeter, a lens or lenses of your choice (see: ProMetric Lenses), calibration(s) of the camera with your chosen lens(es), ProMetric software with 12 month support licence and a hard sided case for safe keeping. All ProMetric systems are supplied as standard with a 2 year hardware warranty. Popular options include an extended software licence or hardware warranty, neutral density filters for use with bright light sources and a geared tripod (or other mounting system). A computer is required to run the ProMetric software (user-provided). On-site training programmes are also offered by Pro-Lite.

Calibrations

Depending upon the intended application, a ProMetric imaging photometer or colorimeter can be ordered with a factory luminance calibration, or a kit that allows you to perform an in-situ illuminance calibration. For near-field measurements, you should specify a luminance calibration (units: candelas per square meter, cd/m2). Luminance calibrations are performed on the ProMetric camera with each lens at a specified working distance. For far-field measurements, you need to order your ProMetric instrument with an illuminance calibration kit. This comprises a high power projector light source with diffuser to create a Lambertian illumination pattern on a user-provided matte white screen. An illuminance photometer or colorimeter is also required (see: Photometers).

Prometric cameras are normally calibrated to CIE standard illuminant A and D65 colour points with reference to an incandescent source. For improved colorimetric accuracy with narrow linewidth sources such as LEDs and LCDs, a factory spectroradiometric four colour or multicolour calibration is available. Please note that ProMetric software allows a user to create their own device-specific colour correction calibrations, provided that they have access to a suitable spectroradiometer.
