$15 shipped within USA.
It looks the same as AmScope SM20 2X Barlow Lens For SM and SW Stereo Microscopes. Mounting size is 1-7/8" or 48mm in diameter. Working distance is 30mm.
I bought two of these as new ad only need one. So this (unused) one is for sale. I am listing this one as used, because I cannot find its original packaging. Otherwise it looks new (and is in very good optical condition).
I used my copy with mounting putty and tape it on a Bausch Lomb Setreozoom 7. Image was pretty decent. The 2x lens has a wider view field than what SZ7 actually needs.
AmScope and its other sellers claim "Its retail value is $180". You be the judge :-) I say it is worth $20 for sure but not a lot more.
Local pick up in person and combined shipping discount is possible. Please message me.
Will trade for a 0.5x Barlow lens.
Thank you and have a great day!
Sold
