Go ahead and use them...but shoot in B&W.
There are orange filters made for just that...B&W.

The Lee filter system and others like it hold square or rectangular filters. Perhaps you could place your material in an opaque 100 mm square card or adapter and place ot in one of those filter system holders that mount on your lens. For that matter, I suspect Lee has already done all the work for you. They make a huge variety of filter colors.

Duct tape. There was a contributing photographer in popular photography used a piece of duct tape to hold the cokin filter on the lens.
He didn't like the holder.

Consider Gaffer's tape. It is easier to remove and doesn't leave the goo behind.

I've started exploring the world of the ultra-small with a compound microscope and colored jells and old plastic sunglass lenses (especially polarized) make interesting filters to bring out the colors and details of the samples on the slides.

If you have an old filter that you have no use for, you can take it to an optical lab along with your new filter material. They can remove the old glass from the ring mount, make a pattern, and cut a new lens from the material. They should be able to mount the new material in the mount. Any lab that makes glasses should be able to do this.

Hi all,
I recently picked up some orange UV ski goggles which are mostly orange but rather interestingly make the greens pop, I tried to replicate this with an orange filter but i guess unsurprisingly it pretty much makes everything orange.

The effect of the glasses seems to increase sharpness and contrast and the greens are different grass is more emerald green and horse chestnuts a lime green. Makes everything a bit brighter too.

I managed to find on Amazon a pair of laser safety glasses which is designed to filter UV and blue light very similar to the first pair. It's a polycarbonate material but now I need to mod this to fit a lens.

Any ideas?

Okay, I know you don't work for NASA!

Personally I have tried placing colored contrast filters that I have had since my film days over lenses on my digital camera. Nothing useful came from this. About as horrible as a similar filter used with Kodachrome Film. The only "pigmented" filters I use for digital photography are Infrared passing ones for IR photography using an non-converted digital camera. I also have a IR converted cameras where the needed filters are installed over the sensor directly. Digital cameras seem to go crazy when trying to white balance non-RGB data. Note, a yellow filter is minus blue light. Magenta minus green, and so forth. Not sure that your laser glasses are even removing polarized light like sky glasses are. There is something else going on that I do not know. But I know many even low-power laser light can damage your eyes as well as digital cameras.

Yes in davinci resolve the scopes show the red and green channels have a full scale range and the blue channel values are much reduced which may mean the effect could be reproduced digitally. it's kind pf similar in a way to false color Infrared photography. different materials have differences in opacity to some wavelengths. Some trees go from blending into the others to really standing out from the crowd. In video it's kind of similar to a wes craven film. On a cold gray rainy day it becomes light and warm.
