SpectraCal SC-METCR250 overview

  • 1Description

The CR-250-RH Spectroradiometer / Spectrophotometer from SpectraCal is a device with a spectral range of 380 to 780nm that measures the spectral power distribution of a source using 10 to 10000 Hz custom synchronization frequencies. It has a 50mm lens and a CMOS image sensor with 256 pixels. The CR-250-RH is designed for display inspection and calibration or for mounting on fast moving XYZ tables. Its small size and shape allows for several devices to be mounted in the same motion control system and the simultaneous measurement of several spots in the same display. The CR-250-RH is a USB 2.0 compatible device, remotely controlled by the host software from a personal computer, laptop, or net book. In addition, it can be controlled by an Ethernet 10BASE-T/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port. A USB 2.0 cable and universal mounting bar are included.

Machined Aluminum & Stainless-Steel Housing
Machined aluminum and stainless-steel housing can withstand high acceleration rates for motion positioning systems and environments.
Optional External Trigger Port.
The CR-250-RH 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.
Designed for the professional calibrator, the CR-250-RH provides a large spot size on contact measurements and a small divergence angle, which keeps the measurement spot size within desired dimensions for display panels and projectors calibrations. The rubber hood allows you to safely position the meter against the screen providing a shield for ambient light.
Custom Color Matching Functions
The CR-250-RH supports uploading up to three sets of custom CMF's. These "custom" CMF's can be alternate standards proposed by different organizations such as Judd-Voss 1978 or custom CMF's that a researcher may be working on.
CRIApp Application
The CRIApp application is a streamlined, cross-platform, user-centric application designed to perform colorimetric-based analysis.
Cross Platform
The working environment is the same in every platform while taking advantage of features specific to the host operating system.
The user interface is designed with a user-friendly approach with controls at your fingertips, not hidden away in menus or complex preferences.
The software is engineered to support simultaneous data capture from multiple connected instruments based on the contextual task at hand. You can select an instrument to take a reading or simultaneously use all open instruments.
Data Visualization
Measurements are presented in a customizable tabular grid or charts. The software supports multiple types of measurements that can co-exist within the same streamlined interface.
Spectral Auto Interpolation
The spectral data view supports automatic interpolation of spectral data so that it provides seamless comparison between unlike spectra.
This device uses NIST traceable calibration standards at a color temperature of 2856 Kelvins.
