TheMaya2000 Series’ high-speed electronics have been designed for considerable flexibility in
connecting to various modules and external interfaces, including PCs, PLCs and other embedded
controllers, through USB 2.0 communications. Its USB 2.0 interface enables full spectral scans into
memory every 7 milliseconds.
The Maya2000 Series Spectrometers operate via USB interface. External triggering is not supported by
the Maya2000 Series Spectrometers.
Models
The Maya2000 Series Spectrometers consist of three models, the Maya2000 and the Maya2000 Pro, and
the Maya2000Pro VIS-NIR. The Maya2000 has been discontinued. While these spectrometers have
similar performance for most parameters, the Maya2000 has slightly faster readout time, and the Pro
offers better dynamic range and signal-to-noise. The May2000Pro VIS-NIR offers high sensitivity in the
NIR range while the Maya2000Pro offers high sensitivity in the UV range. See
for a side-by-side comparison.
