20220623 AFM is unavailable. The mirror of the optical head may be disaligned. -->07/20 Fixed. Available. Kusakabe
20181026 Available now. The broken component was replaced. Inoue
20180930 AFM is unavilable (The cantilever holding part of the lid was broken.) Inoue
20180621 The compressor was finally fixed by the company. Inoue
20180118 The compressor was broken again. AFM is still available (Vibration may affect image quality a little). Inoue
20171117 Pressure of the table is low. The compressor was broken. -->11/24 Fixed. Available. Inoue
20150716 Present scanner = Tube scanner. (Please let Inoue know if you want to change it.)
20150108 You are recommended to check the z-axis scale of N-point scanner by yourself or use the tube scanner if you need high-resolution measurement. The N-point scanner has been unstable. Inoue
20141125 The optical head was sent to the company and repaired. DIF and FFM is stable. Inoue
20140912 Measurement sometimes fails during scanning, probably due to degradation of the optical head part. Will be fixed. Inoue
20130201 Calibration problem
20121102 The new scanner was found to show mirror-reversed images due to a failure. It will not be fixed. Please reverse images after measurement using some image editing. (Correct (not mirror-riversed) images are taken by the old scanner.) Inoue
20121009 Calibration of new scanner may be OK. You need to turn on/off the scanner controller in addition to the station. (See new manual.) Appropriate values of I- and P-gain are different from the case of old scanner. Relatively lower values seem to be suitable. Inoue
20120927 It takes about 15 min to change the new scanner to the old scanner or vice versa. Please let me know if you would like to change the scanners. Inoue
20120917 A new piezoelectric scanner is available. However, z-axis calibration of the new scanner hasn't been completed yet. It will be done soon. Inoue
Old scanner (Tube scanner): maximum (x, y, z) = (25, 25, 1) [um], open loop
New scanner (N-point scanner): maximum (x, y, z) = (70, 70, 2?) [um] , closed loop
