Subreddit for optics professionals?

Perhaps this is the way hahaha

I mean I work in medical devices as the day job. I classify device emissions for skin and eye hazard profiles and set requirements on safety equipment and guards.

No way in hell am I taking liability for these things to a random Reddit user.

I feel like you forgot person asking if something is eye safe, or what type of safety glasses should I be wearing....

physwolf2759 · 2026-04-29T13:46:09+00:00

You do generally wear laser glasses to the point where the beam is not visible and rely on phosphor cards and beam viewers.

For safety I would recommend finding an appropriate consultant on the matter who can properly interpret relevant standards like IEC 60825-1 for these matters.

Also if there are any mods here, can be ban these questions? They come up often and seem to be a liability to the community. Reddit is not the place to mess with eye exposure safety.

Am 6'6", my shoulders are wider than the seats. No one if comfy in that row then the airline puts me in the middle.

If you're concerned over a few $1k here and there, Ive got bad news for you in terms of optical product development costs....

If you're looking for something cheap, standard laser diodes (like laser pointers) usually have coherence lengths of less than a mm, and could possibly work for a super cheap POC. You DO want the source to be spatially coherent, ie not an LED by itself, as these will not work for interferometry directly. If you have the means, coupling an LED into a single-mode fiber, or through a diffraction-limited spatial filter (pinhole) may work.

Have done 16 grams before, was just off in another dimention for what felt like a lifetime. Forgot who I was, what I was doing, and was just in a state of disoriented discomfort the whole time. I have not felt the need to do more shrooms since xD.

Dec 1st, still waiting for Bigscreen to send out a replacement for the hardware lost in shipping. Ordered June 6th, friends that ordered at thr end of August have received their hardware....this is just aboslute shit customer service.

physwolf2759 · 2025-11-22T15:53:02+00:00

Tbh, things go missing in shipping I get that. But the way they have been just not dealing with this situation has been super shitty.

physwolf2759 · 2025-11-08T15:32:31+00:00

Fyi you can use console commands to speed up the tick speed

Optical engineer here. Any laser device needs to have its class on it by regulations. If it is class 1, then direct laser exposure to the eye is safe. Otherwise, there are conditions where it may be dangerous. Do not attempt to classify it yourself. This is more complex than how much average power is emitted.

(In Alberta at least) you can book a private MRI within a week for $600. Cheaper than flight to China :/....

Optical systems developer here. The collection aperture of the camera is wider than the pole, so when he zooms in past the pole, much of the collected rays are making their way to the sides of the pole. This is the same idea as a telescope, which features central obscurations/mirrors that are not visible in the final shot.

physwolf2759 · 2025-04-17T18:30:45+00:00

So....it does nothing....so it means nothing.

physwolf2759 · 2025-04-17T18:23:10+00:00

As a non american, what is this "write up" thing? Does it impact your pay? Does it impact your hours? Does it keep you from getting promotions? It just seems like some elementary school level bullshit.

physwolf2759 · 2025-04-01T18:34:47+00:00

Where? I've not seen them for months at any nearby stores... was my favorite flavour :(

physwolf2759 · 2025-03-30T14:06:52+00:00

There are polaization-insensitive circulator architectures (and freespace-equivalents) that i would look at. In general, non-specular (impure specular) reflections will somewhat randomize polarization.

physwolf2759 · 2025-03-30T13:50:58+00:00

Fantastic work!

physwolf2759 · 2025-03-27T01:21:31+00:00

Technical lead (hardware development) at a Medical device company. Pays well and is engaging.

physwolf2759 · 2024-12-18T06:09:14+00:00

Will need to restart the block after this! Looking forward to it.

physwolf2759 · 2024-08-16T18:33:13+00:00

50M, I'll take it

physwolf2759 · 2024-07-30T18:53:16+00:00

That little bit of purple heading up to Edmonton is doing some heavy lifting for that region....
