Someone as probably already asked this. If they have, i cant find it. But, im going to make me a custom laster case with maple wood and 1/4" acrylic sheets (24x24"). The case will be tall enough to hold my camera and my laser on extension for tumblers.
What i am wanting to know is “window Tint” or “window film”. I am looking for a typle of film that i can put on time lf the acrylic to protect my eyes so i want have to wear any eye protection when i am using my laser.
Does anyone have any options on this that they would recommend???
There’s no such products available.
None that work/protect anyway.
In theory, there’s no technical reason why such a product couldn’t exist, but since the market for such a product is pretty much 0, I doubt there’s ever will be either.
Unlike for CO2 lasers, for visible spectrum diode lasers it’s really hard = expensive to produce transparent sheets that at the same time offer adequate protection, and let the operator to see what’s going on.
That’s the reason for seemingly outrageous prices of industrial grade postcard sized protective windows, and for goggles/glasses.
If on a budget, a camera with either a digital or gel type filter (or both) is really the only option to actually observe the laser in action.
My job has some extra welding curtains they dont use. There RED, it helps the other employees thats walking around the shop protect their eyes from the welding.
No, unfortunately not.
It is the wavelength of the different lasers that determines what protection can be used.
For my diode laser I made a box with a yellowish-reddish color that provided some protection from reflections from the diode. But I was good at using laser protection glasses for extra personal safety.
I think that shiny metal or other shiny surfaces like mirrors are the most critical materials to process with a laser, because this is where you can actually get reflections in your eye.
Thats interesting as I’m feeling its the way to go. I at last got the invoice for the screens for my enclosure (combo IR1064 & blue diode 450nm)…no glasses yet.
I would just feel way happier watching a monitor or small screen, for myself or visitors.
I was hoping to use an old phone with a filter placed in front.
As I currently only need the information whether the laser is lasering or not, and a ballpark of the location, there hasn’t been need for me to experiment with that yet, but I suspect that if a good resolution and contrast is required, a pretty narrow gel-type “band-pass” rather than a “narrow band cut” filter is required, coupled with a digital filter just for power scaling.
Or alternatively, a “narrow band cut” for just the laser wavelength to reduce the camera cell overloading, and all the rest is done digitally.
I have way more experience on manipulating light with gels (stage lighting) than digital manipulation of a video signal, so it’s probably the former for me.
There’s no right or wrong way to do it though, the end result is the only thing that matters.
The beotch of it is that just like with every other similar application, the filtering has to be tuned to that particular cell/optics/amplifier combination, so what works with one combination may not work with another.
That said, the “cost” of a system like that is pretty much all in the experimentation time though, digital cameras are really cheap, and a couple cm2 of gel is virtually (or even actually) free, just as digital filtering is.
I introduced myself to (ND) filters yesterday and came across Band filtering also, so I understand now that laser safety filters and optical filters are dissimilar.
I would really like to use my phone screen to see whats happening in there, primarily to observe air flow. I’ll be using P1P21 safety screen and would like to just place the phone in the front view window or top. I’d also prefer no cables etc.
One thing I forgot in the arch lid design, was to allow height for phone window. Ive got a feeling a/the right (ND) filter will do the job and at very low cost but would like ‘Ideally’ a combo filter for IR1064 2w and 450nm diode…as with safety glasses.
Once I have initial setup running & become familiar with LB screens/tools, I may look further into actual lasering video using mini cam etc.
Salute! to the film & stage industry. My last exploit in horticulture was at Troy studios, working on a series called ‘Nightflyers’ based on Sci-Fi novel by Isac Asimof. I built the biodome forest on board the space ship…in studio and other location set’s.
Great working with & roasting coffee for production, camera & lighting crews.
Hard, fast work but best time ever!
True, but in the case of just preventing overloading the camera cell on a narrow(ish) wavelength band, they are similar enough.
If on a budget, that is .
If not on a budget:
That will work a lot better, and probably with minimal experimentation.
While it may work well -a lot better than a makeshift gel filter in any case- there might be one issue though.
Unlike camera filters, screens like that usually do not have anti-glare coatings needed for optical lens systems.
Easy to test though.
Indeed, they do make the magic happen
That is really, really cool.
I might need to revisit that series, bio-domes have been close to my heart ever since my view of the space travel as well as environment was forever altered by watching the SciFi classic “Silent Running” as a pre-teen in the late 70’s.
As a sidenote, the novel Nightflyers was penned down by George R.R. Martin though, better known for … well everyone probably knows what .
Probably not his strongest genre, and the show was cancelled after the first season.
There’s sadly not too many filmizations of Isaac Asimov’s work, there should be more.
And based on the success of the recent Foundation series, there hopefully will be.
It usually is.
As was doing live sound in the late 90’s, sadly I haven’t been involved in film industry, save for being an extra in a Finnish comedy flick back in the day.
If p1p21 might work, then I would sacrifice a bit of the top viewing screen to make a lense protector. The material should be here mid next week…Great idea!
Also I’m trying to locate a endoprobe cam (actually in stock!) with no app needed and a 1-1.5m cable for my Samsung phone…good for viewing from various angles and I think it could be really helpful maybe, for focusing the dot…and it has lights!!
Speaking of Sci…I was having lunch at Troy one day & chatting to a guy about this n that and he asked if I was into SciFi Super heroes and stuff. I said not really…I prefer SciFact like Lyal Watson ‘Super Nature’ and stuff like that, but I thought Deadpool was great & flawless! He had to go after a time & someone else told me he was a co creator of Marval.
Im wondeing if the lense tint material you mentioned would help with possible lense flare on the camera probe.
You’re welcome.
And as the screen actually blocks that particular wavelength, it should be easy to cut the needed small protectors with Your laser, so minimal waste.
I bought one ages ago for entirely different application, but haven’t gotten around installing it onto the laser head.
Even though there’s been quite a few opposite views as well, IMO a head mounted camera would be beneficial in gantry type diode lasers as well.
If the inbuilt lights are used, the protective lens most likely need holes for those lights.
Otherwise the reflections inside the protective lens probably blurr up the image.
In any case, if the camera has a focus feature, there has to be some method to manually adjust the focus -and obviously disable the autofocus- otherwise the camera focuses on the surface of the protective surface when the light is on, possibly when the light is off and the laser beam is on as well.
great story.
I do admit that I haven’t personally met or worked with many famous people, but the few I have met or worked with, have been surprisingly nice and friendly.
The ones on their way to (imagined) fame on the other hand, almost always unbearable to work with, let alone to chat with.
I’m not that into superheroes either, I prefer “Space Fantasy” like Star trek, Star Wars, Babylon 5 etc.
But I do agree that Deadpool is great.
Humour does make superheroes more bearable
Possibly, about the only way to know is to try how it works.
