Apart from moving house and a subsequent covid infection, no.

At the moment recovering, but no energy to tinker with lasers.

Thanks for asking.

Re: Questions about Osram PB530 laser

Just to be sure: I expand the laser beam, point at a glass plate and see if the reflection on a wall has those dark bands At the moment, the expanded beam looks very noisy, is this a product of dirty/wrong lens? It looks like your using a coated lens for a different wavelength, if you dare to remov...

Re: Questions about Osram PB530 laser

That could come from the lens you are using. In any case a spatial filter is a good investment in holography :) I have a spatial filter, but have issues aligning the two lasers correctly, let alone getting the filter aligned properly with one or both. It will be the next step though. Steep learning...

Re: Questions about Osram PB530 laser

I show you the setup so you can duplicate ... if dark steady bands are not seen we need to retune it .. Just to be sure: I expand the laser beam, point at a glass plate and see if the reflection on a wall has those dark bands? If not, I turn the little screw on the blue block? Clockwise or the othe...

Re: Questions about Osram PB530 laser

Does it have to be in Instagram? Can't you just post it on this forum? The video isn't to clear (to me). It seems to show an expanded laserbeam being reflected on a glass plate onto a wall. The reflection on the wall shows steady dark bands. Apparently that is what I need to have, but am unsure how...

I will check out those fringes, I assume I have to do something with the little screen on the driver?

Questions about Osram PB530 laser

I recently purchased from eBay a PB530 laser from holokidd, together with his red laser. I have never recieved a package from the US this quickly, he is the fastest seller I've ever had on eBay. In the item description it is stated tuning has to be done according included instructions, but such inst...
