New compact colorimeter that measures to human eye standard

Dunedin, Florida (August 26, 2008) - Ocean Optics (, the industry leader in miniature photonics, has announced its partnership with Admesy ( to provide the Brontes Colorimeter for color measurement in online applications.

The Brontes features 5,500 color measurement per second and 18,000 luminance measurements per second in burst mode. Color is measured using photodiode sensors and an XYZ interference filter. It has 8 selectable luminance ranges with a lowest luminance level of 0.05cd/m². Supported color spaces include XYZ, Yxy, L*a*b*, Y'u'v', LCH. Also supported are color temperature and dominant wavelength measurements. The Brontes is especially useful in situations where speed and stability are key demands.

The device interfaces with a PC using USB2.0 or RS232 and can be interfaced with embedded systems using either the same connections or I²C, available via a GPIO connector. Besides connection to PCs or embedded systems, the Brontes can also operate as a stand-alone unit for Go/NoGO measurements. In stand-alone mode it recognizes color or luminance/transmission, which are teachable by the end user.

The colorimeter comes with standard software applications for measuring and storing data. Additional developer source code is also included for LabVIEW, C++, C# and VB for end users who prefer to design their own applications. The unit also features the USBTMC class, which ensures it operates directly in Test & Measurement environments, such as National Instruments LabVIEW, through the VISA USB device drivers. Drivers are available for Microsoft Windows, Apple OSX and Linux.
