Easy to Use

The PR-655 menus are accessed via the on-board, 2.25" x 3" high resolution, full color touch screen LCD display and 5-way navigation keypad. Following a measurement, the PR-655, displays data and color spectral graphs on the system display. The PR-655 design provides stand-alone operation - no PC required and can also be controlled via SpectraWinTM 2 software or by using text based commands (Remote Mode). All communications are via the standard USB interface or the optional Bluetooth or RS-232 interface.

Versatility

The unique design of the PR-655 makes tasks such as spectrally based photometric and colorimetric measurements, source spectral power distribution, dominant wavelength and correlated color temperature quick and simple.For applications other than radiance or luminance the PR-655 can be supplied with optical accessories such as a cosine receptor for irradiance/illuminance. LR-127 LED Analyzer for testing LED's to CIE 127, fiber probe for remote non-line-of-sight luminance testing, and a series of magnification lenses for small spot size analysis. An RGB Display Caloption is available that provides an interactive method for white point calibration based on spectral measurements.

Wide Dynamic Range

The PR-655 provides a dynamic range of 0.2 fL to 30,000 fL, without the need for any external neutral density filters - ideal for contrast and brightness measurements of display panels and a wide spectrum of other target devices.

Connectivity

It's easy for the PR-655 to talk to the outside world - it comes equipped with USB and Bluetooth (optional) wireless interfaces. It is supplied with remote control capability using simple text commands and a USB driver that emulates an RS-232 interface (COM: port) making it a simple task to generate custom programming to perform specific tasks or for seamless integration into an ATE environment. If required, an optional traditional RS-232 Interface can be added.

Create regions in the CIE 1931 chromaticity diagram that act as Pass / Fail criteria. If the measured color falls in the specified region, Pass is reported on the instrument display or Fail if the measured point falls outside the region. The measured point and region are also displayed on a color 1931 CIE diagram. Regions can be defined as squares, rectangles, polygons (3 - 10 sides), circles or ellipses. When not enabled, a full color CIE 1931 Chromaticity Diagram with measured point is displayed.
 
6655-0003-10 Color Rendering Index (CRI)
 
Calculate all 14 CRI indices and the average CRI (using indices 1 - 8). User selectable or automatically generated reference. CCT and chromaticity tolerances are also set by the operator. Results are reported on the instrument display.
