Hi all.  I am putting together room specs for new microscopes.  Has anyone measured real heat production from all diode based confocals (no argon lasers, no mercury bulbs). Actually real heat loads from any microscopes would be interesting (probably to many of us).

I would guess that almost 100% of all consumed electric power ultimately goes to heat.

In my experience the ideal room temperature for the Microscope room is about 72F. Our systems never failed due to heat generation in the room. Also, I have to mention that the argon-ion laser installed in 2001 still working in the Biorad system without any trouble. Of course the laser power went down, but still works. I believe that the temperature maintenance in the microscope room helps a lot in the operation of the high-end microscope systems.

To clarify, I am hoping to find out how much heat is put out by the microscopes, not power used (which is an approximation) or what temp the room should be at.  As we all know gas lasers pump out thousands of BTU (between 4k and 6k/hour) mercury sources pump out between 1k and 2k BTU.  These are the reasons we need to spend so much on air handling for scope rooms. Equally all the old computers/monitors/hardware all produced buckets of heat... Nowadays with all diode lasers, all diode light sources, LCD displays, efficient scan heads etc the amount of heat produced by microscopes has gone down enormously.  The numbers from vendors are very conservative, and are probably not actually measured.... so does anyone have any real numbers?

Hi Simon,

My experience with setting up new systems is that wattage has a direct relationship to heat production, even though the labels may be for peak power consumption.  Turnkey systems will provide you with a total wattage of the system, or you can go through each item and total it up.  Either way, total watts gives the heating/cooling guys a reasonable figure to work with.  Local heat sources, such as argon lasers or multiple power sources/computers in a rack can be selectively vented to avoid their contribution to the heat load in the entire room.

  I've found that the stated current requirements are usually much higher than run time use, and even startup draw.  Our old Bio-Rad's electronics added up to about 16 A on a 20A circuit and ocassionally tripped the breaker. Our electricians put an ammeter on the breaker and found that even with powering up that monster CRT display, it never drew more than 4 A.  the problem was a surge suppressor with strange harmonics.

The specs for the lasers on our FV-1000 suggested that separate 2000 VAC line conditioners were needed for the Ar ion laser and the rest of the lasers.  Actual loads were 54% and 5%, respectively, according the conditioner readouts.

Has anyone tried the home power usage monitors like the Kill-A-Watt to monitor actual power usage?

This has been an interesting thread.  To take the question one step
further... have any of you measured the impact of thermal drift
throughout your systems? I'm interested especially in the impact on
the stand itself, the objective, the stage, the camera mount, etc.

Thanks,
