• Measures seeing parameters using Differential Image Motion technique
• Operates with the images in focus on the detector
• Images separated with optical wedge
• Reimaging optical system places filters and aperture stops in parallel light
• Filter wheel allows measurements in multiple pass bands
• Up to 6 filters may be used
• Up to 6 aperture/wedge configurations may be used
• Convenient focal plane position with independent focus adjustment
• Invar spaced optical elements to minimize focus shift with temperature
• Remote control of filter wheel and aperture wheel by system controller
• Full control of the CCD camera including subaperture downloading, integration time, and binning
• Performs autoguiding and star centering functions |
