Unique Design

The PR-670 SpectraScan is the newest addition to the world renowned SpectraScan colourimeter series of instruments. This unique, portable battery powered instrument utilises a fast-scanning 256 detector element spectrometer with a spectral resolution of 1.56 nm per pixel and is supplied with 4 automated measuring apertures (1°, ½°, ¼° and 1/8°) and automated measure shutter. Other hardware features include AutoSync® for automatically synchronising to the source refresh rate insuring the utmost accuracy, an external trigger port allowing remote measurement activation from either a push button or peripheral device, a Secure Digital (SD) port for measurement storage, and a long lasting rechargeable Lithium-ion (Li) battery.

Easy to Use

The PR-670 is controlled via the on-board, 2.25" x 3" high resolution, full color touch screen LCD display and 5-way keypad for easy navigation. Following a measurement, the PR-670 displays data and colour spectral and CIE graphs on the system display. The PR-670 design provides stand alone operation - no PC required. The PR-670 can be also controlled via the world famous SpectraWin software over the USB or Bluetooth interface or using text based commands (Remote Mode).


The unique design of the PR-670 makes tasks such as spectrally based photometric and colourimetric measurements, source spectral power distribution, Colour Rendering Index (CRI), dominant wavelength and correlated colour temperature quick and simple. We've further enhanced the flexibility by adding 2 extended sensitivity modes and 4 measurement speeds.

The PR-670 can be supplied with up to 15 filter based remote heads connected to the instrument in a 'daisy chain' configuration to make simultaneous illuminance or luminance measurements - an ideal tool for tasks such as projector uniformity. Select heads for luminance, illuminance or chromaticity.

For applications other than radiance or luminance the PR-670 can be supplied with optical accessories such as a cosine receptor for irradiance / illuminance, LR-127 LED Analyzer for testing LEDs to CIE 127, fibre probe for remote non-line-of-sight luminance testing, and a series of magnification lens for small spot size analysis. In fact, all of the accessories available for the PR-650 SpectraScan can be used on the PR-670.


It's easy for the PR-670 to talk to the outside world - it comes equipped with USB and (optional) Bluetooth® wireless interfaces. It is supplied with text based, Remote Mode syntax and a driver that emulates an RS232 interface (COM: port) making it a simple task to generate custom programming to perform specific tasks or for inclusion in an ATE environment. If you want, we can optionally add a traditional RS232 I/F.
