QUESTIONS & ANSWERS
Ask a Question-
Greetings, I would like to know about the 30x18 triplet loupe, specifically about its field stop/CA. Other technical details or a full technical sheet would be highly appreciated, thank you.
There is no field stop and no data sheet (and I really don't know how to give a measurement of CA /chromatic aberration!). However, if you go to our article LOUPES COLMPARED and scroll to about half way down, there's a section about 30X loupes complete with a photograph of what you see through this lens. .
If for jewellery, and you want the best, don't go for 'the strongest', go for the best quality lens, e.g. ZEISS COMB.

I need a loupe to check my stylus condition on my turntable:what's your suggestion?
Usually a really good quality 10X magnification is best; if you want stronger then maybe 20X... 30X would be for very specialist applications.
I'm not familiar with stylus conditions. To see what various magnifcations look like through loupes, see Loupes compared | Quicktest.
