Ocean Optics has launched the Brontes Colorimeter for colour measurement in online applications.
The Brontes features 5,500 colour measurements per second and 18,000 luminance measurements per second in burst mode. Colour is measured using photodiode sensors and an XYZ interference filter. It has eight selectable luminance ranges with a lowest luminance level of 0.05cd/m². Supported colour spaces include XYZ, Yxy, L*a*b*, Y’u'v’, LCH. Also supported are colour 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 USB 2.0 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 recognises colour or luminance/transmission, which are configurable 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 and measurement environments, such as National Instruments LabVIEW, through the VISA USB device drivers. Drivers are available for Microsoft Windows, Apple OSX and Linux.
