![]() The optical transparency is better than 90% in the range from 200 nm to 5 µm. The versatility is further enhanced by the (optional) optical window which allows irradiation of the total active resonator volume. the lowest Q for the shortest dead-time and largest bandwidth, or a Q matched to the spin relaxation time for maximum signal-to-noise or critically coupled for CW-EPR. This feature allows to match the resonator bandwidth to the specific experimental task, i.e. The resonator Q-factor can be changed continuously from very high to very low by varying the degree of coupling. Quick and easy sample changing is a standard feature at all temperatures even in high power operation. Due to its high filling factor it provides a high sensitivity even at the large bandwidth (low Q) required for FT-EPR spectroscopy. and generates π/2-pulses of 10 ns at a bandwidth of 500 MHz. The ER 4118X-MD5 is the universal probe of the ELEXSYS E 580 CW/FT-EPR X-Band spectrometer. ![]()
