This unique, portable battery powered instrument utilizes a 128 detector element Spectrometer with a spectral resolution of 3.12 nm per pixel and is supplied with an automated measure shutter. A 1° aperture is standard equipment with the PR-655 - an optional 1/2° aperture is available. Other hardware features include AutoSync for automatically synchronizing to the display backlight or source refresh rate insuring the utmost accuracy, an optional External Trigger port allowing remote measurement activation from either push button or peripheral device, a Secure Digital (SD) port for measurement storage, and a long lasting rechargeable Lithium-Ion (Li-Ion) battery.
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.
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.
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.
