Colorimetry Research

This CR-250 Tristimulus Colorimeter/Photometer with ViewfinderKit from B&H can provide spectral information in the 380 to 780nm range. Made from machined aluminum construction, this kit has vibration resistant optical components. The colorimeter has a spectral bandwidth of 4nm, spectral resolution of 1.6nm/pixel, and a spectral accuracy of 0.3nm. The viewfinder features horizontal rotation so that you can ensure your image is level.Features at a Glance Compact and RuggedConstructed using machined aluminum and stainless steel; weighs 1 lb (1.2 lb with viewfinder VO-201)Spectral Bandwidth and AccuracyVisible spectrum (380 - 780nm) with a spectral bandwidth of 4nm spectral resolution of 1.6nm/pixel spectral accuracy of 0.3nmCustom AperturesA single fixed aperture but can be customized when ordering (available at order time: 3, 2, 1, 0.5, 0.25, or 0.125 )Detachable ViewfindersDesigned for viewfinders that are easily detachable and replaceable from the instrument's main bodyDynamic RangeLuminance range of 0.02 to 154,000 nits (0.006 to 46,000 fL); sensitivities measured for 10:1 signal-to-noise (RMS)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 netbook. As an option, the CR-250 can also be controlled by an Ethernet 10BASET/100BASE-TX IEEE-802.3 compliant connection or an RS-232 port.Custom Color-Matching Functions The CR-250 allows uploading up to three sets of custom CMFs, which can be alternate standards proposed by different organizations, such as Judd-Voss 1978, or custom CMFs a researcher may be working on.
