My set up is a Meiji EMZ-5 with a 0.5x barlow lens and a 10x eyepiece. It allows you a range from .7 to 4.5 magnification.
It is worth the expense. There ara used EMZ-5 on eBay for a very good price and condition (not too long ago). The company had plenty of them for sale. Dont have the name present, though.
Oh, but i think ours is a meiji emt. Wonder if i can still add on the 0.5 lens. Cant afford to buy another scope for several hundreds. Just bought a new mill, cam, exocad, comp, compressor, steamer, amscope, ivac twin. And i have to buy all new chairs, a new scanner, high speed handpiece, diamond disc for trimmer, and probably more. Haha. And we are only a 5 man lab. Not sure how i can keep affording this! Just gotta be smart with business plansand vision i suppose. Hard work just thinking about it.
