Re: Новости GEOLA - Фотополимер для голографии Bayfol HX200

Good question Stefano!
If you go to Covestro website, there should be some good info but not addressing this specific question and archival lamination of this material in general.

Looking for Newport MRL-18

Hello,
Looking for a couple of used Newport MRL-18 or MRL-28M mini rails. Aesthetics aren’t important as long as rails aren’t bent.
Thanks.

Straight Clorox bleach in a Pyrex glass dish. Wear nitrile gloves, mask, goggles & do it outside or use a fume hood.

Newport 935 series variable attenuators?

Wondering if anyone has any experience with these Newport 935 series high power variable attenuators? Reading the description, they don’t exactly sound like the 930 series beamsplitters.

Re: Geola question

Geola is selling Bayer/Covestro panchromatic HX200 photopolymer. Don’t know if they’re also selling some other photopolymer as well... if you’re referring to HX200, it’s definitely sensitive at 640nm. I’ll leave it to you to research online😊.
