CR-250 Spectroradiometer / SpectrophotometerCOLORIMETRY RESEARCH
- Compact & Rugged: Constructed using machined aluminium and stainless steel and weighs -1 pounds (450 gms) [1.2 pounds (540 gms) with view finder VO-201].
- Spectral Bandwidth & Accuracy: Visbile spectrum (380 - 780 nm) with a spectral bandwidth of 4 nm; spectral resolution of 1.6 nm/pixel; spectral accuracy of ± 0.3 nm.
- Custom Apertures: A single fixed aperture but can be customized when ordering (available at order time: 3°, 2°, 1°, 0.5°, 0.25°, 0.125°).
- Detachable View Finders: Designed for View Finders that are easily detachable and replaceble from the instrument's main body.
- Dynamic Range: Luminance range of 0.02 Nits to 154,000 Nits (0.006 fL to 46,000 fL) (sensitivities measured for 10:1 signal to noise (RMS)).
Designed for PERFORMANCE
The ruggedly constructed housing of the CR-250 is made of machined aluminium and stainless steel, and can withstand high acceleration rates for the most demanding motion positioning systems and environments. All optical components are fixed to ensure that no optical misalignments occur due to vibration, shock or high acceleration/ deceleration rates.
It weighs only 1.2 pound (0.54 kg), and it is the perfect tool for display inspection and calibration and for mounting on fast moving XYZ tables. Its small size and shape allows for several CR-250s to be mounted in the same motion control system and the simultaneous measurement of several spots in the same display.
Versatile INTERFACE options
The CR-250 is a USB 2.0 compatible device, remotely controlled by the host software from any personal computer, laptop or net book. As an option, the CR-250 can also be controlled by an Ethernet 10BASET/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port.
Optional EXTERNAL TRIGGER Port
The CR-250 can be equipped with an optional External Trigger Port which enables remote measurement activation from either a push button, a peripheral device, or by hardware trigger signals to measure strobes/pulsed lights, and start/stop signals. This option is ideal for fast temporal events that need to be precisely synchronized for measurement or data capture.
Screw-on rubber hood adapter is included for contact measurements. Measurement spot diameter on contact measurements is 8 mm for a unit that has a 2 degree aperture and 14 mm for a unit that has a 1 degree aperture.
Custom COLOR MATCHING FUNCTIONS
Future proof your CR-250 with additional custom color matching functions.
The CR-250 allows uploading up to three sets of custom CMF’s. This “custom” CMF’s can be alternate standards proposed by different organizations, such us Judd-Voss 1978 or custom CMF’s a researcher may be working on.
And lastly, Powerful application.
The CRIApp application is a streamlined, cross-platform, user-centric application designed to perform all colorimetric - based analysis. It provides a familiar and consistent workspace no matter which platform you are in. The CR-250 comes standard with a built-in, easy-to-learn command interpreter, for users to quickly create their own dedicated software to perform specific measurement tasks or for inclusion in an Automated Test Environment. In addition, a fully documented communication language with numerous real-world, sample templates are included as starting points for customers to build their own software tools using any of the modern computer development environments. LabVIEW driver is available upon request.
