The 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 Maya2000 and Maya2000 Pro, which offer greater than 90% quantum efficiency, high dynamic range and excellent deep-UV response (<190 nm).

Advantages of Back-thinned FFT-CCD Detectors

Back-Thinned CCD area image sensors have high UV response, great signal-to-noise characteristics and wide dynamic range, making them especially suited for low light level applications. Because of their great native UV response, FFT-CCD detectors do not require the application of UV-sensitive coatings, which is common with standard CCD-array detectors. That’s important because batch-to-batch variation can be problematic with some UV coatings.

• Maya2000 Pro has >75% quantum efficiency; Maya2000 has 90% QE

• USB 2.0 interface

• Low-noise electronics

• Optical resolution to ~0.035 nm (FWHM); resolution depends on groove density of grating and size of entrance aperture (slit)

• 14 grating options (ask us about options that provide expanded range).

• Slits available in widths of 5 µm, 10 µm, 25 µm, 50 µm, 100 µm and 200 µm

• Optional propriety order-sorting filters to eliminate second- and third-order effects

• Maya2000 offers the detector collection lens option for enhanced signal collection

• Fully controllable strobe signals (single or continuous)

• 10 onboard digital user-programmable GPIOs

Maya2000 Nitrogen Purgebox

The Nitrogen Purgebox gives you the ability to measure under nitrogen flushed conditions. Use it for applications where oxygen is negatively influencing your measurements - like deep UV (below 190 nm). The Nitrogen Purgebox helps eliminate absorption from oxygen.
