Red Polarisation rotator/waveplate needed

[Dmax]

I need to mix two red 638nm beams together I already have a PBS cube so I'm looking for a Red Polarisation rotator/waveplate, could anyone here direct me to a good supplier ?

Rotators for laser systems - Opt Lasers - Opt Lasers

In our offer you can find rotators for different wavelengths. Rotators are used to rotate the polarization axis of a linearly polarized laser beam.

There are actually a lot of cheaper options, I tried one for just over $ 1, and they did very well with red, $ 69 is super expensive.

Yes they are super expensive, but I am using OPT rotator and PBS cube to combine 2 x nubm44 and OPT says 1% loss max, but if cheaper rotator works without too much loss I will try it, do you have a link for 445nm-455nm rotator that can take 7.5w ?

Is yes please post a link, Thanks.

I bought them on taobao,but maybe you can't
you also cacn buy on ebay,i seen some seller sell them 5$/pc, These mirrors always have good performance, they do not lose energy like lenses

They are not mirrors but wave plates/rotators
You use them with a PBS cube to combine 2 beams and have a perfect overlap, otherwise if you use a PBS cube to combine you must turn one laser 90 degrees.
