Developed as a Pump-Probe spectrometer, the CLARiTY VF is now offered as our least expensive scanning UV, Vis, or full range UV/Vis CLARiTY.

 

Your VF will be produced with one lamp, two lamps, or LEDs, as is best for the intended use.

• For absorbance protein studies: UV, 240-400 nm (deuterium lamp).
• For the absorbance electron transport region: Vis, 400-600 nm (tungsten lamp).
• For absorbance UV/Vis scanning: 240-870 nm (deuterium and tungsten lamps).
• For fluorescence and Pump-Probe work, wavelength specific LEDs are used instead or of in addition to the steady-state lamp. LEDs are the preferred illumination source when rapid on/off cycling is required
• Single grating monochromator with scan rates to 20 nm/ second
• Exquisitely sensitive photon counting detector, full range 230-870 nm
• Integrating cavity up to 8 mL to be used for direct sample introduction or by means of a 1 mL or 150 uL test tube.

 

Specify optical train for absorbance or fluorescence:
Absorbance = light source, monochromator, sample, detector
Fluorescence = light source, sample, monochromator, detector

 

CLARiTY VFA: For cells, mitochondria, algae, and other biological systems. Scanning monochromatic light for absorbance & fluorescence excitation with fixed lambda emission.

 

CLARiTY VFL: For inorganics, organics, nanoparticles, and more. Shuttered broadband light (through optional filter) for absorbance & excitation, with scanning emission.
