Dear all, The Argon laser of the Zeiss Exciter is broken as it will not ignite anymore. I will contact Zeiss and get it replaced. Please take into account that you cannot image with the 488, 458 or 514nm laser until it is replaced. I will inform you when it will be operational again. Also, I just heard that the red control diode monitoring the output of the laser on the Exciter has been broken for some months without me knowing about it. The red control diode is essential to monitor the laser output and to guarantee a long lifetime of the laser. Going into the red equals driving a car at 6000rpm. It will last a while, but not very long. In the future, please inform me of any malfunction on any of the microscopes the moment you encounter it. It is very well possible that we killed the laser prematurely due to the malfunction of this diode, which is really stupid. Have fun imaging, Daniel -- ================================================================== Daniel Van Damme Tel:+32 (0)9 331 39 33 fax:+32 (0)9 3313809 VIB Department of Plant Systems Biology, Ghent University Technologiepark 927, 9052 Gent, BELGIUM dadam@psb.vib-ugent.be http://www.psb.vib-ugent.be ==================================================================
