Phosphor Evaluation System
1. Introduction：
The Resonance Phosphor Evaluation System uses a computer-controlled tunable vacuum ultraviolet light source with design optimized for test of phosphor emission and luminescence. It delivers vacuum ultraviolet (VUV) excitation wavelengths to samples on a target holder and measures their spectral phosphorescence with a fiber optic coupled CCD spectrometer. This is an excellent system for quality control, fundamental research and development of VUV and UV excited emitting materials.
2. Features：
· 120 to 400 Nm Tunable Light Source with 0.15 to 10 Nm Spectral Bandwidth
· Reference VUV Solar Blind Pmt for Tunable Light Source for Absolute VUV/UV Flux onto Sample and Transmission of Sample
· 10 Sample Positions on Standard Wheel
· Modular Design Allows Change of Emission Sources and Detection Optics
· Compact Footprint less than 1 Sq. Meter
· Turn-Key Oil Free Pumping System
· Emission Spectrometer Uses High Sensitivity UV/Vis/Nir Pmt for a Wide
Spectral Range from 200 To 900 Nm.
· VUV Solar Blind Pmt Transmission Detector
· Order Sorter with 2 Long Pass Filters
 · Labview Based Software with USB Interface
