When you switch between objectives, you don't want to have to refocus every time. By getting a [b]microscope[/b] with objectives that are parfocal, you'll be able to move between <b>objectives<b> without much need for refocusing.

Are you able to focus on the specimen? Is the problem the same if you switch to a higher magnification lens?
Could be several things, a slider half way in, a turret not clicked in to the notch, ie condenser, a filter partway in.

I own a MRJ-03 Premiere microscope with the a bad electric board. How can I get spare parts for it? abnernm@hotmail.com


I have the same problem and can't find parts anywhere. Premiere Microscopes doesn't answer their phone or return calls and their customer service email keeps rejecting everything I send. Please let me know too if there are parts available for this microscope.

Manual


I found out that Tasco microscopes have been discontinued quite some time ago. A Company called Bushnell 1-800 423-3537 who gave me the number of ABO 305-859-2010 Tasco microscope 750X # 60750-0 call after 3pm. They do not have my manual but can answer questions or send a similar manual. I have to call back stiil hope this helps. Zoom
