技术参数：
RESOLVE ANALYSER
半径: 120mm
反转角度: 180 deg.
透镜型号: Multi-element high transmission
入口狭缝: 6 sets positioned at entrance to hemispheres, used to vary analysed area
at the sample (also one factor determining energy resolution)
5x10mm 2.5x10mm 1x10mm 5mm? 2.5mm? 1mm?
( alternative slits / aperture sizes by special request )
分析区域： at the sample is approximately the same as the input slit size, the lens
having nominal magnification of X 1
出口狭缝:
RESOLVE MCD5 has ‘Standard’ and ‘High’ resolution defining exit slit mechanism which
is independent of the entrance slits)
