Question about Tasco 750 Monocular Microscope

Optic lens tube separation

We have 20 monocular Leica BME scopes. Several of them have had the tube that holds the optic lens separate from the rotatable head of the microscope. What is left is a black fitting with a square glass peice in the bottom. Is this a friction fit or a glued joint? They are very loose and no longer snug up. Would you suggest a glue that can be used or is there a better fix to this problem?

Hi There,

I understand your problem and I would
Recommend stud-fix by Loctite, making as sure as possible that the tube occupies the exact same place as it did before removal (at right angles to the optical axis)
If I can be of further assistance, please do not hesitate to contact me.

Optic lens tube separation - image.php?productid=16148Sir,your microscope tube with the eye piece is screw joint with microscope body. Rather part is friction fitted as well as there is a proper place to mount can do the gluing but first of all be clear that part should be not a movebale part other wise you will have dificulty for fine focusing.
for the further quotation dont be hazitate,

The tube joint was a friction fit that had become loose. Most of the time it is a screw joint which is why I was confused. We put some electrical tape around the inside portion of the fitting and the tube fit snugly down over it. We'll have to wait and see how long it lasts.

The focus knobs drift

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.

Hi, I am searching for cytovision software for karyotyping compatible with the Leica DM 1000 research microscope in our lab. Kindly suggest and oblige, Thanks

Hello, a very late solution to your problem but........

If you have a DM1000 you can add cytovision to your system contacting Leica who now own cytovision. You will likely have to purchase a new camera to be compatible with the software but they can provide you with everything necessary.

Is Primostar microscope really made in germmany?

This from clinicalmicroscope,com .....

Carl Zeiss is a German brand that is popular for making quality optic lenses. Just like Leica, Zeiss has facilities everywhere in the world. The high end clinical microscopes are made in China and Mexico but Zeiss continues to deal in the United States.
If you had a model number (and year of manufacture) it might be possible to trace, I'm guessing you've not got the original instructions, because it should say there. On a technicality - it doesn't have to say "made in germany" anymore - it would just have markings for Europe.

Classroom scopes get dirty very fast. This can cause the images to look dim and faded. Contact a Microscope Service Company. If you are in the Arkansas area that would be: Delta Optical Instruments, Inc. Email:

There are 4 major brands (Zeiss, Nikon, Leica, and Olympus) that sell to universities etc but these are more expensive than some other manufacturers that are less well known but with high quality standards (Motic, Meiji). A well designed site with pricing information is The owners are knowledgeable and helpful. Always look at the scope with your samples or request an evaluation period on the PO.

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)
