No view I just got this scope and I can't see anything in it; not even light. I think something is broke but I don't know enough about it to be sure. I hope you can help me. Thanks. Carey

Re: No view

Lenscap? if this is a manual mirror version (light is provided by reflection from a swivel mirror under the sample. this mirror needs to be in the correct position for you to see. also check your optic selection, (switch to a different lens) see if this helps, (you may also not be selected properly)

We are using our Nikon Eclipse e200 for the first time and we cant get the stage handle to move the glass slide up and vertical. It moves horizontal but not vertical. Is there something we need to detach...

If this is a brand new scope then there is most likely some packaging or packaging tape that is preventing movement. Scopes are meticulously packaged because they can be rather delicate instruments. In some rare cases the scope may be damaged in shipment.

How do I increase the field of view on a zeiss OpMi-1?

Field of view and working distance vs magnification is a law of physics. Using the lowest power gives you the widest field of view and greatest working distance but the trade of is that you loose magnification. Conversely as you increase magnification you decrease working distance and you loose field of view diameter.
The optics of your microscope are limited to .4x to 2.5x magnification. Your working distance is limited to 200 - 400mm depending on the magnification you are using.
I am not aware of any interchangeable lenses for this scope.

Just acquired a used "Micromaster" scope from

Sounds like you have the wrong bulb installed. This scope requires a 6v-20w halogen bulb. They are available from: Delta Optical Instruments, Inc. email:

The stage slides down on its own and the view gets out of focus.

Just inside the coarse focus knob you will see a "chrome" ring with holes it it. That ring needs to be tightened just a bit. It will make the coarse focus knob stiffer so tighten only enough to stop the downward drift of the stage. A funny looking tool should have come with the scope. It is used to adjust this "tension" ring.

Swift microscope no 634008 having problem staying in focus when switching magnification

First, a scope of this grade will not be completely in focus as you move from one magnification to the next. But it should be close enough that you do not loose your point of interest.
Be sure you are not pressing down on the stage specimen platform as you change magnifications. It is very sensitive to pressure. Also, be sure that the coarse focus tension is tight enough that the platform is not drifting down imperceptibly as switch magnifications. Look through the scope and watch if the image goes out of focus while you are watching it. If so, you have what is called "stage drift". This is corrected by tightening the tension on the coarse focus knob.
The tension adjustment is on the coase focus shaft. It looks like a chrome ring with about 3 holes in it. There should have been a strange looking tool that came with your scope. It is used to adjust the tension. If your specimen is "drifting" out of focus, simply tighten the tension ring a little bit at a time until the specimen no longer goes out of focus. Do not get it so tight that it is not easy to operate the coarse focus knob.

How do I fix a mechanical stage from ''drifting'' downwards? Won't stay in position.I move the stage up into position under the objectives but as soon as I let go of the knob the stage drifts right back...

You need to tighten the coarse adjustment so it generates enough friction to keep the stage in place. How to tighten it will vary from scope to scope, but most just have the screws on the knob (metal circle inside the knob with two holes in it). To adjust this type, you'll need a special key wrench.

I need software for my Boreal digital microscope

You won't find the software online.
You have two options.
One, and probably the best one, is to try to get it directly from boreal. Perhaps they'll even have it for you to download on the web from a secure portal or something.
The other, less likely option, is to try to scam it off ward's. Email customer_service at, claim you bought a boreal digital scope off them and see if you can get them to direct you to the download or a way to get the software. Since all digital boreal scopes work on the same digital camera, the software should be the same for most of the scopes.

Can stained bacteria be seen with a 40x magnification microscope? not in detail, just enough to determine coloration of individual bacteria

Hello--I understand that you need at least 600x to view bacteria and some say 1500+ so 40x doesn't seem to be in the right mag. area at all--not sure this helps much.You could purchase a 100x obj. and 10/15x eyepieces but will probably be into oil immersion for the obj.Possibly a 20x eyepiece + a 60x obj will give you a degree of definition.I use a SEBEN Bino with this combi and it gives a small view but not good.kind regards martin r

Hi there,

Seing bacteria isn't just about magnification, many
are transparent and need to be stained. Even at X1000, you will see little detail, but can make approximations of shape etc. Here is a good starting point for staining bacteria.
With a toothpick scrape a little plaque from your teeth (size of a pinhead is plenty). Put this in the centre of a slide with 1 drop of water and mix thoroughly. Allow this to dry then pass the sample through a flame three or four times (hot, but not hot enough to burn fingers) Stain for five mins using either Methylene Blue or Eosin. If you don’t have these, Blue or Red fountain pen ink will do for starters. Rinse off excess stain with very slow running water. Blot dry and observe at X400. If you have an oil immersion lens, you must use a cover slip and mount your specimen in balsam first.
If I can be of any further help, please don’t hesitate to ask.
