LARRY USB2000 and LARRY USB4000 series: Scientific-grade CCD Linear Array Detectors
The LARRY USB series is a family of linear CCD array detectors that offers cost-effective, scientific-grade performance for a wide range of spectroscopic applications. They can be mounted to most spectrographs that have the output plane ≥10 mm outside of the spectrograph. Both standard and custom mounts are available, making them ideal for upgrading existing systems or incorporation into flexible new spectroscopic instruments.
The LARRY USB series is a custom build 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 via USB 2.0, allowing for easy-to-use, plug-and-play operation. Multiple detectors can be controlled in the same software, enabling simultaneous acquisition. GPIO communication can also be used to integrate with other instruments and devices.
The linear CCDs used in the LARRY USB series contain on-chip electronic gating, which allow for integration times down to 1 ms without the need for external shutters.

1Shorter integration times, down to 10 μs, possible with an alternative software package (Ocean View). Please contact us if you require this option.
2Spectral rate is based on Ocean Optics SpectraSuite software, and may depend on the PC specifications and configuration. Eliminating unnecessary background processes is recommended for high-speed operation. High-speed acquisition mode does not support multiple detectors.
