Fluorescence Spectrophotometer F93, 365 nm Standard Excitation (CAT#: STEM-AL-8827-ZJF)

The F93 is a fluorescence spectrophotometer intended for routine fluorescence spectroscopy with LED excitation. It uses a low-temperature LED source to excite samples and a monochromator to select fluorescence emission wavelengths. The source identifies a 365 nm excitation source as the standard configuration. Manual grating wavelength scanning is used in the C-T optical system. A photomultiplier-tube receiver detects the emitted fluorescence signal. RS232 communication is provided for external data transfer. The normalized record retains only technical information supported by the source. Overall, the instrument provides an LED-excited fluorescence platform for routine spectral measurement.
