Uncooled High Precision Slits

In this high precision slit system a flexure mechanism is used to move the slit blades over a small range while maintaining a high level of parallelism. Optional items include manual or stepper motor driven operation, a linear encoder to indicate aperture position, feedthroughs to enable measurement of the photo-current from each blade for beam position and intensity monitoring, a motorised stage for longitudinal positioning of the slit, and mounting on a synthetic granite plinth.
