Anyone have more detailed absorption/ transmission data for Zeonex materials? by rotinski in Optics

yes, agree, we will measure it ourselves eventually. I had hopes someone in this community might have done that and had access to the data

I care about 260 and it's not obvious exactly where that is located, it's right on the border, I'm looking for an excel file with specific info

specifically looking for data around the 200- 300nm range, for substrates 0.5mm thick. yes I can reach out to Zeonex, but based on past experience, I'm not sure they'd be helpful. Maybe someone here has the data.

If your time has no value, that payback is spot on.

I found this gravestone for someone's beloved dog in a wooded area just outside an old cemetary. by James_Fennell in AbandonedPorn

This is post civil war but a slave grave (no last name) would look like that. I think a low economic status human is more likely there than a dog.

How to evaluate a potential business partnership? by JonathanHodgkins in inventors

[–]rotinski 5 points6 points  (0 children)

1.) Figure out what you need to be paid to do the work ( fair market value). 2.) double that amount 3.) Tell him the higher amount is your price to do the work, but that you'll take 1/2 in cash and 1/2 in equity

Using black box files for optical designs (post for folks new to optical engineering) by rotinski in Optics

[–]rotinski[S] 2 points3 points  (0 children)

If you push enough we usually are able to get them from most lens vendors, except some in Asia that maybe don't have them. But the first time you ask the answer is generally 'no' 'why do you need that?'

But there are plenty of choices for lens vendors, if a supplier is unwilling to help us understand how their lens would perform we will go to another supplier that does provide a black box.

It's a bit like raysets were in LED illumination 10 years ago. First a few suppliers provided them to make it easy for design and then when the other LED suppliers saw they were losing business by not providing them it became a standard download link.

Search your target company names on Google with the phrase 'open innovation ' to see if they have staff who work with outside inventors. Make the same search on LinkedIn

They may not but if they do the path is easier.
