When we designed our new lab, we investigated which equipment is subject to damage.
Our multiphoton laser (Coherent chameleon Ultra II) has a built in safeguard with an internal battery sufficient to cool down the laser. The software reports the state of the battery. This is not written in the laser specs so it is worth asking the company if they have such a system or not.
Argon lasers will get their lifetime reduced if repeatedly turned off without cooling but there is no impact if it happens seldom. This is a problem if it happens often as seems to be the case in your institute.
The rest of the equipment (cameras, computers...) can be turned off suddenly without damage.

However the main problem is the spike that occurs when one turns the power back on. This is very damaging for a lot of equipment including the computers. It is very important to have a good spike protection system. Alternatively unplug all equipment before the current returns or setting the fuse back on and painfully replug them a few at a time.

Med vänlig hälsning / Best regards

Hi Mario,
We use APC Back UPS Pro sinewave units for a lot of sensitive equipment including CCD and CMOS cameras, test equipment, and other science-related instruments.
They have an excellent track record and reliability.
Eg BR1500VA and other models.

Hi all,

We are unfortunately facing many unplanned (random) electricity outages/voltage variations in our Institute (it's a very old building) and our systems (and particularly lasers) don't like it too much... I was wondering if some of you are using UPS units to protect your confocal/2-P systems? If so what type of UPS are you using? All the info you could provide would be most welcome, thanks in advance.

Mario
