Wave plate
Anybody tried this wave plate ?
Yes, I saw that .Pau wrote:Be aware of the small 13mm shorter dimension. Just after reading your post I clicked the buy button...I'm trying to cancel the order
If cut in half, it could be placed somewhere close to the back of the objective. Another question - how cut it in half nicely this thin thing ?
Yeah, it is standard procedure with glass..normal thickness glass ...ChrisR wrote:Find a piece of sharp tungsten carbide. A corner on a new masonry drill is sharp enough. That'll scratch glass much more easily than a normal glass cutter. Then of course it snaps easily.
Did you try with this thin stuff ?
I don't know what "this stuff" is made of, but I've cut coverslips and slides easily. The point is you need a very sharp hard tool to scratch the glass with little pressure. Normal glass cutting tools need too much pressure to make the scratch.
If it's crystalline and you scratch it, & constrain the bend to the scratch, I wouldn't expect a problem.

Thanks Chris, you calmed me down ! So I bought it, let's see what will happenChrisR wrote:I don't know what "this stuff" is made of, but I've cut coverslips and slides easily.

... probably wasting your time but why not use these?

Any idea how this film affects image quality if placed above the objective ?
For below I'm using this polarizing assembly (tried different celolphanes), for now I'm pretty happy with it

I use the retarder film on top of a quality polarizer, which I then place on top of my Optiphot field lens. Guess I didn't understand your application.
