HORIBA FluoroMax-4 Spectrofluorometer 

The HORIBA FluoroMax-4 Spectrofluorometer typically operates across a spectral range of 200 nm to 950 nm for both excitation and emission, often utilized for UV-visible fluorescence measurements. The system features a 150 W Xenon lamp, with standard detectors optimized for the visible region (up to 850 nm). 
 

Technical Specifications:

* Excitation/Emission Range: 200–950 nm.
* Emission Detector Range: Standard R928P PMT operates from 200–850 nm.
* Monochromator Range: Excitation (220–600 nm, blazed at 330 nm) & Emission (290–850 nm, blazed at 500 nm).
* Spectral Bandpass: Continuously adjustable from 0–30 nm.
* Wavelength Accuracy: ±0.5 nm.
