- Temporal resolution: LARRY: 5 milliseconds GARRY 10 microseconds
Ames Photonics LARRY and GARRY series are two families of linear CCD array detectors which offer cost-effective, scientific-grade performance to suit a wide range of spectroscopic applications. They are compatible with virtually all commercial spectrometers, making them ideal for upgrading existing systems or for incorporation into flexible new spectroscopic tools and instruments.
Supported by a wide range of accessories, including software packages for data acquisition and analysis, mounting hardware and more, these are ideal detector choices around which to configure a modular solution for your spectroscopic application.
The LARRY series (pictured) is ideal for general spectroscopic purposes.
The GARRY series (below) is designed primarily for applications requiring synchronization to pulsed sources, or for other time-sensitive measurements. These detectors incorporate on-board gating electronics.
All of our scientific-grade detectors are carefully tested and sorted as part of our stringent manufacturing and opimization process. We guarantee that they will exhibit no fringing effects across their full spectral range. All detectors include UV grade fused silica windows and are sensitized with a proprietary coating to extend performance from below 200nm to above 1100nm.
Array Lengths and Pixel Sizes:
The LARRY series comes in three different lengths, corresponding to either 2048, 3000. or 3648 pixels in the CCD array. The 2048 element CCDs have an individual pixel size of 14 microns (w) x 200 microns (h). The large pixel size makes them an ideal choice for general spectroscopic applications.
The 3000 element linear CCD arrays have a pixel size of just 7 microns (w) x 200 microns (h). This model has been designed to provide an effective trade-off betwen spectral resolution and sensitivity. Due to their narrower geometry, these 3000-element dectectors will naturally collect only half as much light as a 14 micron wide pixel array, but they also provide twice the spectral resolution. In practise, the reduction in sensitivity due to narrower pixel size is not a limitation as it can be compensated for at the data-processing stage.
To accomplish this, our SpectraArray SL and SpectraNet software packages now support 2x, 4x and 8x horizontal binning. In addition, in-built smoothing algorithms enable these detectors to simulate 14, 28 and 72 micron wide pixel detectors. The horizontal binning technology can also be applied to the 14 micron wide detector arrays; in this case, individual pixels then appear as 28, 56 and 112 micron wide and signal is increased proportionately.The 2048 and 3000 element CCDs can also be supplied with optional TCDC (Temperature Compensated Dark signal Correction) technology, which eliminates the need for background to be taken and subtracted from the signal when making a measurement.
For simultaneous acquisition from more than one detector head the SAM (Simultaneous Acquisition Module) interfaces are available.
