Deep uv spectrometers
Deep UV excited Raman & photoluminescence spectroscopy is an emerging analytical instrument technology with vast potential for a wide range of commercial, industrial, and research applications. A significant limitation of Raman spectroscopy conducted in the near UV, visible, or near IR is obscuration or interference of the Raman signals due to background fluorescence from the analyte or its background or surroundings within the laser beam interrogation spot.
mini deep uv pl/raman systems
The Mini PL 110 is a miniature instrument employing a scanning monochromator with a detector with gated boxcar integrator and averager with a nearly 7-decade dynamic range.
Measurement of photoluminescence (PL) spectra from wide bandgap semiconductor materials is a vital characterisation method and is widely accepted. In addition to PL spectra, the Mini PL 110 can also be used for Raman analysis with a 35 cm-1 resolution. However, the Mini PL 110 uses a monochromator and not a spectrograph. The spectrum is generated by detecting each spectral increment separately and sequentially, unlike a spectrograph, which detects the entire spectrum at once. |

TRADITIONAL DEEP UV RAMAN & FLUORESCENCE SPECTROGRAPH
DUV Raman PL 200 is a more traditional, but still miniature, deep UV Raman and fluorescence spectrograph employing a TE cooled back-thinned, back-illuminated CCD array detector.
A significant driving motivation for deep UV Raman methods is an avoidance of fluorescence obscuration or interference with Raman spectral emissions. A second driving motivation for the DUV Raman PL 200 is the ability to detect both Raman and fluorescence emission, which provide different but complementary information about a targeted material. A third driving motivation is the ability to detect & map biological material, which is not possible with 1064 nm, 785 nm, or 532 nm Raman methods. |
