Re: CNI MGL MBL 4 Watt Lasers

That sure looks like a telescope to me, and cheap too. He normally doesn't ship to Alaska here I'm at, but he did for the CNI lab laser, but had to ask for him to remove the restriction.

I'm not sure about the AR coating, I will have to ask.

Re: CNI MGL MBL 4 Watt Lasers

I'd buy it myself for that price, if you don't.

I listed my labby on ebay: CNI MODEL MGL-4W 4 Watt Output 532nm Green DPSS Lab Laser - Also made a thread in the BST section, as soon as it is approved members can buy it from me through LPF, but not before approved. 30% discount to members.

Re: CNI MGL MBL 4 Watt Lasers

It looks like a high quality lens, but I want to put cylindrical pairs in front of a nubm44 and a nubm07e, I am about to start on the 07e and just use the 3x that's been used for the mitsu 638.

Anyway I have boxes of lenses and many irons in the fire, I just ordered ZVS and a spark coil, I may be building a 10um leaf toaster, but I will limit the current and have a start and run circuit.

My knife edging project is going on the back burner for now and I may pay more but I will get the exact telescope or build one, I'm just not sure about that AR coating.

Sorry for the long winded retort, if you want it grab it. It is a nice looking piece, easy to dissemble too I bet. It could have a nitrogen fill so conceder that if you dissemble.
