Where to Buy Fluorescence Spectroscopy Equipment

We offer a number of OEM spectrometers that are well suited for fluorescence spectroscopy. The ultra-compact PEBBLE VIS and the high-resoution FREEDOM spectrometers are recommended for portable and handheld applications and our high throughput ROCK spectrometers for applications requiring high sensitivity.

Our transmission grating based spectrometers are ideally suited for fluorescence spectroscopy due to the following benefits:

• full spectrum in one measurement
• compact size
• fast spectral acquisition
• robust design enabling stable operation
• low unit-to-unit variation enabling transferability

Iceblink is a supercontinuum fiber laser covering the 450–2300 nm spectral range with 3 W of average power and superior stability (<0.5% std. dev.). It is a very versatile white light source with a world of applications in the scientific and industrial sectors, including absorption/transmission measurements for material characterization, VIS, NIR and IR spectroscopy, single molecule spectroscopy and fluorescence excitation. The spatial coherence and broad spectrum of Iceblink makes it a great alternative to classic lamps, single-line lasers, LEDs and ASE sources.

Our supercontinuum lasers with built-in pulse picker in combination with our tunable SuperK VARIA filter is an extremely useful excitation source for time-resolved spectroscopy experiments. With its broad range it replaces solutions based on combining several lasers. It also eliminates time-consuming hardware modifications and alignments that would normally be required while switching excitation sources. The pulse picker can reduce the repetition rate to secure enough time for the photo-excited materials to reach their ground state before the next photoexcitation-fluorescence cycle is initiated.

GWU's portfolio of CCD based spectrometers provides a great variety of features to fulfill nearly any requirement in a wide range of applications. Compared to traditional, large spectrographs, spectrometer devices of this type offer competitive performance in a small package and a high value for money. The detection range covers the UV to the near infrared and even reaches out to the mid-infrared at 2.6 µm. Models with tiny footprint, e. g. for wavelength monitoring in OEM applications, as well as thermo-electric (TE) cooled devices with high resolution, high sensitivity and ultra-low noise for weak-light applications, such as fluorescence sensing or Raman analysis, are available.
