 Maya-pro 2000The Ocean Optics line of high-sensitivity back-thinned 2D FFT-CCD spectrometers for low light-level, UV-sensitive and other scientific applications now includes the uncooled Maya 2000 and Maya 2000-Pro, which offer greater than 90% quantum efficiency, high dynamic range and excellent UV response. |

Advantages of Back-thinned FFT-CCD Detectors Introducing Maya 2000-series Spectrometers If $10,000 is a little bit out of your budget range, and if long integration times aren’t part of your application, the Maya 2000 and Maya 2000-Pro may fill the bill. Indeed, at introductory prices of just $4,800 and $5,800, respectively, Maya 2000 and Maya 2000-Pro offer great value and performance for most any application requiring high sensitivity, good UV response and great dynamic range. While Maya 2000 and Maya 2000-Pro have similar performance for most parameters, the Maya 2000 has slightly faster readout time and the Pro offers better dynamic range and signal-to-noise (see comparison tables for a specification-by-specification analysis). Also, please note that limited detector availability may make lead times longer for the Maya 2000. Maya 2000: $4,800 Maya 2000-Pro: $5,800 |

Our Maya2000 Pro® Spectrometer offers you the perfect solution for applications that demand low light-level, UV-sensitive operation. This back-thinned, 2D FFT-CCD, uncooled instrument offers greater than 75% quantum efficiency, high dynamic range and UV response
to 190 nm and lower. The Maya2000 Pro can deliver accurate analysis down to 185 nm with high dynamic range and
good signal-to-noise ratio.
The Hamamatsu FFT-CCD detector used in the Maya2000 Pro has excellent performance characteristics. Because of their UV response,
FFT-CCD detectors do not require UV-sensitive coatings and provide performance advantages such as low dark current and good signal
processing.
Maya2000 Pro has very good response across the UV and is a great choice for vacuum ultraviolet applications such as analysis of semiconductor
materials, measurement of biological samples and noble gases, and determination of chemical elements such as sulfur.
