1/2 wave plates are ready to go

[Doc]

Has anyone ever tried to cut one of these in half?

They are 1/50" thick; good luck with that.

[Solarfire]

Put me in for 2 x 640nm unmounted.

Cheers!

[FourDee]

...Why in the sam hill??

To make 1/4 wave plates of course ...

Hey,

The mounting rings are 25mm dia.

At this stage, I dont think there will be enough interest to get the 532 or 660nm plates.. That being said, I still have a lot of 660nm unmounted plates sitting here

What will the surrounding mount be like?
They might be an obstruction yet would make them easier to handle and strengthen them.

Has anyone ever tried to cut one of these in half?

Alright alright! I goofed, in that I had not freshly re-read this thread, the general knowledge was there and certainly an intent to buy!
Having mentioned that I will add that I was looking at this on ebay:
http://www.ebay.com/itm/4-Spectra-Ph...item3f0d1c1b1a
and the plates appear rectangular. I was not sure whether a WP could be both round or square and thought the plates in this GB were square.

@FourDee that reply really made me laugh!
@Dave I have asked you about buying 5 of 660 plates from you in that sales thread of yours.

I am still in need of all the other plates I ordered in this GB.

Peace

Edit: I used to work at a place where we cut glass, I did not do much of the manual cutting but did do some. I was just thinking of cutting one in half if it was rectangular/square.

I would like to see what these mounts look like before coming to a decision on the number of them to include with this order, could somebody please post a few pictures or point me to a post where somebody shows these WP's being used with the mounts?

Thanks!,

LaserCo....These are pics from a previous GB of mounted waveplates from Dave. The dimensions of the plate and mount are the same...12.5mm and 25mm....so...I would think that the current offering is the same. The mounted WP is shown placed in a custom brass holder I machined. I would go with a mounted optic. These are very nice units Dave is selling...and a great price !! Thanks...Sir Dave. BEAM

hey, thanks for offering an extra 445 wp

joking aside, i did order just one, but leave the second in for the time being, as tentative.
thanks!

[lange5766]

Hi Dave,

At Post 213, i ordered (not LaNeK779):

If the 532nm come to fruition, one mounted 532nm half wave plate additionally for me.

Thus for me entirely;
lange5766: 640nm - 2pcs mounted, 445nm - 2pcs mounted, 532nm -1 pc mounted

(plus "Item 16.. 4pcs unmounted 660nm 1/2 WP" from your Workshop cleanup lots of useful stuff here!)

Thanks : Marco (lange5766)

These 'many items' group buys always get a bit messy, sorry guys..

Just corrected I think.. Ill send messages to everyone confirming individual orders.

Hey mate, not sure if you caught this...

Hey Dave, please can you count me in for one for the red project I've been discussing with you? Thanks mate

...though I'm not sure whether I'll need a wave plate. Until I find out the beam specs of the Opnext 63133 diode with the 4mm Optima lens, I don't yet know whether my stacking will even require a PBS to get the 12 diodes into the rather large CNI green. In fact I may need to double the divergence to get it to match in which case reverse telescoping a 4x3 stack may be the way to go.

So if it's not a hassle to have one extra in your stock, cool. If not then please can you add one 640nm wave plate for me?

Thanks Dave

[dave]

Will PM everyone tomorrow and get this in motion.

[dave]

OK, I should have PMed everyone here ( except you Tony - I will get a few of each spare so if you do need one, consider yourself covered )

I just had flashbacks from the mass emails i sent out with the last WP GB Haha

[taggalucci]

Thanks muchly Dave

[Bbe]

Hi Dave!

I'm not late? If not - 640-2pcs mounted, and 445-2pcs mounted.

Thaaanks!

[LaserCo]

Dave put me down for one more 445 and one more 640, both mounted
and add 2 of your short footed flexmounts @ $22 (is that already converted to AUD? thru cookies/location?) each

[LaNeK779]

PP sent. thanks for doing this!
