CCD-Based Imaging Photometers

Westboro Photonics P6E Series CCD Imaging Photometer

Westboro Photonics CCD sensor-based imaging photometers are offered with a choice of 4 to 12 mega pixel sensors for the measurement of 2D luminance (cd/m2) and illuminance (lux). The P6E Series are supplied with matched, electronically controlled lenses and feature a thermoelectrically cooled CCD sensor for enhanced performance at low light levels.

Westboro Photonics P6E Series CCD Imaging Photometers


The P6E Series are high performance imaging photometers based on TE-cooled CCD sensors with 4.2, 9.1 and 12.0 megapixels. Unique to these instruments is the integration of electronically controlled lens functions with iris and focus control. These motorised lenses offer improved accuracy, precision and convenience for all applications. Stabilised Peltier-cooling of the CCD detector minimises measurement noise and drift. With sensitivity below 0.0001 cd/m², ultra-low light signals can be reliably analysed.

Measurement Capabilities

The following photometric parameters can be measured using a P6E Series CCD imaging photometer:

  • Spatial luminance (candelas per square meter, cd/m2)
  • Spatial illuminance (lux, lx)
  • Source luminous intensity (candelas, cd)
  • OPTIONAL radiometric measurements (radiance & irradiance)

Matched Lenses

Each photometer has a lens that is matched to the sensor resolution and size, providing optimally crisp and clear images. By matching a lens to a particluar sensor, the images created using a Westboro photometer can be of a higher quality that supposedly higher resolution cameras without matched lenses. Standard lenses offer fields of view from 5˚ to as much as 57˚. Microscope lenses are also available.

Radiometric & Other Capabilities

Upon request, a P6E Series CCD imaging photometer can be factory configured with a radiometric filter, which provides for measurements of irradiance and radiance. The radiometric filter replaces the standard phoopic filter, and extends the wavelength sensitivity of the camera to that of the CCD sensor, 350-1000nm. Calibration of the imaging radiometer must be performed by the user with reference to a spot spectroradiometer which is used to measure the output from the device under test. Other optionally available filters match the scotopic and circadian spectral sensitivities; IR and custom filters are also available.

Capable Software

Photometrica® software and optional software packages provide extensive options for measurement and analysis. The optional Photometrica Software Development Kit (SDK) allows for the creation of fully customised solutions using built-in scripting or external control.
