1/2 wave plates are ready to go

[edison]

That,s a good idea. A PBS with a waveplate on top is not so fragile and easy to install.

If they are available i would like to have a couple

One for 445 and one for 660.... thank you sir

When I asked about a thicker plate, the company suggested the possibility of gluing a thin wave plate to a thicker piece of optical glass, however, they were worried this wasn't a good idea, as it would sacrifice the wave plates flatness.

Can't we get a PBS with a waveplate already glued (with optical glue) on one side.

Ok, Ill get something designed up, but maybe not until after the weekend. I don't think a retainer will be very expensive, I guess around the $10 mark. More likely even less if the wave plate is simply glued into the ring, rather than having a second threaded ring to screw the plate in... Ill draw up some designs, and see what the group thinks.

That would be a much better proposition, and make the plates much easier to handle safely, if you are able to, and don't mind organising it .

Planned time scale depends on how long the list takes to grow. Hopefully sooner rather than later tho

What is your planned time scale on this?

[loopee]

Hey Dave

Put me down for

1 x 640nm
1 x 660nm

Cheers

Dave,
could you ask the manufacturer if they also fabricate broadband (achromatic) 1/2 wave plates.
One 1/2 plate for all wavelengths between 445 and 660nm.

I would take 4 at 445nm
Maybe some at 640 as well but still looking for a good deal on some 640 diodes.

Hi Dave,

Count me in for 1x 445 and 1x 532 please.

Thanks
