LARRY USB3648+ : Scientific-grade CCD Linear Array Detector
The LARRY USB3648+ is a CCD linear array detectors that offers cost-effective, scientific-grade performance for a wide range of spectroscopic applications. It can be mounted to most spectrographs that have the output plane 10mm outside of the spectrograph. Standard and custom mounts are available. .
The LARRY series is based on proven Ocean Optics electronics and is compatible with Ocean Optics software, enabling a broad scope of features. The detectors connect to and are controlled by a PC (Windows 7, 8, ) via USB 2.0, allowing for easy-to-use, plug-and-play operation. Multiple detectors can be controlled, enabling simultaneous acquisition. GPIO communication can also be used to integrate with other instruments and devices.
The linear CCDs used in the LARRY series contain built-in electronic shutters, which allow for integration times down to 1 ms without the need for external shutters.
