After purchasing the Mantis scope for my business I realized there is a better
way to go then a microscope or in my case a macroscope.   There are  
glasses you can purchase with the high power microscope type lens attached........

are no microscope fans or bulbs to replace over time.

Tried to google them but failed.  Can u pls tell us the name and/or brand so we can research them online?  TIA
