Colorimetry Research CR-250

• Compact & Rugged — Constructed using machined aluminum and stainless steel. Weighs only 1 lb (450 g) on its own, 1.2 lb (540 g) with the VO-201 viewfinder.
• Spectral Bandwidth & Accuracy — Visible spectrum (380–780 nm) with spectral bandwidth of 4 nm, spectral resolution of 1.6 nm/pixel, and spectral accuracy of ± 0.3 nm.
• Custom Apertures — Single fixed aperture, but customizable at order time (3°, 2°, 1°, 0.5°, 0.25°, 0.125°).
• Detachable Viewfinders — Viewfinders snap in and out manually from the instrument's main body, replaceable depending on user needs.
• Dynamic Range — Luminance range of 0.02 Nits to 154,000 Nits (0.006 fL to 46,000 fL), with sensitivities measured for 10:1 signal-to-noise ratio (RMS).

The ruggedly constructed housing of the CR-250 is made of machined aluminum 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 no optical misalignments occur due to vibration, shock, or high acceleration/deceleration rates.

It weighs only 1.2 lb (0.54 kg) — making it the perfect tool for display inspection and calibration, or for mounting on fast-moving XYZ tables. Its small size allows several CR-250s to be mounted in the same motion control system for simultaneous measurement of multiple spots on the same display.

The CR-250 is a USB 2.0 compatible device, remotely controlled by host software from any personal computer, laptop, or netbook. As an option, the CR-250 can also be controlled via an Ethernet 10BASE-T / 100BASE-TX (IEEE-802.3 compliant) connection or an RS-232 port.

The CR-250 can be equipped with an optional External Trigger Port that enables remote measurement activation from a push button, a peripheral device, or by hardware trigger signals to measure strobes / pulsed lights, and start/stop signals. Ideal for fast temporal events that need to be precisely synchronized for measurement or data capture.

The CRIApp application is a streamlined, cross-platform, user-centric tool for performing all colorimetric-based analysis. It provides a familiar, consistent workspace no matter which platform you're on. The CR-250 ships with a built-in, easy-to-learn command interpreter — letting users quickly create their own dedicated software for specific measurement tasks or for inclusion in an Automated Test Environment.

A fully documented communication language with numerous real-world sample templates is included as a starting point for customers to build their own software tools using any modern development environment. A LabVIEW driver is available upon request.
