High-sensitivity Maya2000 Pro Spectrometers

Maya2000 Pro Spectrometers are a great choice for applications requiring high sensitivity, good UV-NIR response and wide dynamic range. Applications range from low light level fluorescence and Raman measurements to absorbance, transmission and emission analysis of solutions, solids and gases.

At the heart of each Maya2000 Pro is a back-thinned 2D FFT-CCD detector we offer two such detector options in a robust, configurable optical bench with low-noise electronics and low-jitter triggering capabilities. Accessory and bench options allow users to optimize systems for setups ranging from the vacuum VUV (as low 165 nm) to the VIS-NIR (especially in the region <780 nm).

Maya2000 Pro Options at a Glance

Maya2000 Pro Spectrometers are versatile. If your application demands great response at lower wavelengths especially <300 nm the Hamamatsu S10420 detector version is your best bet.

For better sensitivity at longer wavelengths (>780 nm), we recommend the Hamamatsu S11510 detector version. Mix and match from a variety of gratings, slits and other accessories to maximize performance.

Also, we offer an application-ready Maya system that is a good option for Raman and low light level applications where long integration times are not necessary. The Maya2000 Pro-NIR, is preconfigured with the S11510 detector, is optimized to 780-1180 nm and includes a longpass filter, 50 m slit and gold mirrors for enhanced NIR sensitivity.

Comparing Maya2000 Pro Options

Maya2000 Pro Detector Response Only

Here is spectral response data that Hamamatsu reports for its S10420 and S11510 FFT-CCD image sensors. Detector response represents just one element of spectrometer system response. System response combines the effects of all the elements of the instrument, including the optical bench design and grating choice.

Maya2000 Pro System Response Spectra

This graph shows the spectral response of Maya2000 Pro spectrometers configured with both UV-VIS (S10420) and VIS-NIR (S11510) back-thinned CCD detectors. Also, the graph includes spectral response of our USB2000+XR1, which has a front-illuminated CCD detector.

In this setup, we measured the relative output of a miniature deuterium tungsten halogen source. A trifurcated optical fiber transmitted signal to the spectrometers, which were set to different integration times to keep within scale. Also, the Maya2000 Pro with S11510 detector required attenuation at the fiber to avoid saturation.
