(9490F-1G) - 1m Monochromator f/9.7 Single Pass

The 9490 monochromator is Sciencetech's second highest resolution monochromator, with 1m focal length. With a 2400 l/mm grating it can achieve resolutions better than 0.01 nm in the standard single pass configuration. This version uses 84 x 84 mm gratings for an aperture of f/9.7.By default the monochromator comes with a single grating kinematic mount. Users can manually swap one grating for another without losing alignment. An optional motorized 3-grating turret is available for automatic grating selection without opening the housing. The 9490 has a flat field output allowing it to operate as a spectrograph using a linear array, multi-channel detector to capture the entire output spectrum continuously. Sciencetech provides a selection of 1" wide CCDs and photo-diode linear array detectors mounted on a multi-axis adjustable focusing platform for use with the 9490.
Some models of the 9490 can be updgraded to dual pass operation (-DP). With the -DP dual pass upgrade option even higher resolution is available by switching to a "double pass" configuration that effectively doubles the focal length to 2m.
