if yes i would like 2 pieces to the netherlands

The AR coating is BBAR, but each wave plate is wavelength specific.

Quite a few people that are marked as unpaid ave paid now. Ill update the list this evening when I get home from work

Cheers guys. looks like the order will indeed be sent off first thing next week.

Dave
If it is not too late I want one for 640nm unmounted and one for 532 nm, also unmounted.
Let me know when and where to pay you.
Thanks
Brian aka Laserbiker

Sorry to jump into this so late, but what I need are half waveplates for 633 nm. I'm not sure that the HWPs in this discussion for 640 nm would be close enough. Is there any way to get some relevant specifications?

Thanks!

OK guys, updated list of payers, and wavelengths and mounting options.

Only a few left to pay. Will chase you up tomorrow

These are the specifications I was given:

aterial: Quartz-Crystal
Dia.: 12.50mm
Thickness: 0.5mm
Retardation：1/2 Lambda or Type: 1/2
Surface quality: 20/10
Parallelism: 1 sec
Retardation-tolerance lambda/300
Transmitted wavefront disortion: Lambda/8
BBAR: 430nm-670nm R<0.5%, 445nm, 532nm

I have been told the bandwidth of these is quite narrow.

OK, the stragglers have all been messaged.

I'm now going to make a cut off of the end of the weekend, tomorrow night.

Ill place a order, hopefully on Monday.

A few hours later they get woken up by an email alert on their phone which is saying something about paying for a group buy on PL........

Hahahahahaha this really made me laugh out loud ooh my monitor is dirty where did I leave my duster? BRB door bell, ahh there's my duster, what did I need that for? Never mind, that reminds me did you catch Never Mind the Buzzcocks on TV last? Shit, the door..........etc

I would buy a 445 if it also worked with 473.
