Larry USB Series

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.

The Ames Photonics LARRY USB2000 and LARRY USB4000 scientific-grade detectors are excellent for reviving or upgrading spectrographs. These cost-effective detectors incorporate a Ø42.5 x 6 mm mounting boss, identical to that of Newport Oriel LineSpec detectors. This allow for easy coupling to many popular spectrographs such as the Oriel MS125 and SPEX 500M ½-meter spectrographs. In fact, these detectors can directly replace the Newport Oriel LineSpec CCD detectors, but at a fraction of the cost.

The LARRY USB series detectors are fully compatible with Ocean Optics software, enabling a broad scope of features and long-term, up-to-date software and hardware support. For integration into existing systems, these detectors are compatible with and fully controllable via the Ocean Optics OmniDriver SDK, as well as LabView.

Ames Photonics also offer a variety of mounting adapters and plates for integrating the LARRY USB series detectors into other instruments and devices, with custom plates/adapters also available.

Compatible with:

  • Newport Oriel spectrographs such as MS125, MS127i, MS260i, FICS
  • SPEX 500M ½-meter spectrographs (replaces 1451X exit slit assembly)
  • Any other spectrographs with output plane ≥10 mm outside of the spectrograph
  • Other devices - let us know and we can customise an adapter for you!
