Before you say no (without reading), I'm alredy know that is very very not recomendable.
I get a piece of welding glass for a mask, I alredy read about the bad idea of using for protection since only work for a UV, now, I own a cheap 532nm "100mW" laser (not idea the real mW), I know it bleeds IR, I have work with IR ligth before, a few moths ago I mod a digital camera (an some webcams) to a IR camera, I test the laser with it and emit a lot of IR (nothing new). So I get the welding glass for another purpouse, to used as polarized filter for long exposure photos in sunligth, but the glass is too much darker that I tougth, I can se a really few things, mostly only withe things in direct sunligth, so I tested for IR filtering with the camera, I expect to see it almost translucid (sun glasses are almost clear in IR camera) but it seams that block all the IR the camera can detect, I even pointed to the sun a I can barely see a yellow circle, then I tested with an full-range camera (another camera moded, but without filters, can see UV as well as IR and visible ligth) for UV with some leds I have (400nm aprox), the camera can see just a little point of the leds, with red leds can see better, but IR leds not even a point, and those are more bright. So next step was tho test the laser, the IR camera can see an bright white point, and the full-range get so much light taht I'm not sure if it's white, green, or mix of two, depends on surface and angle, with the glass in front of the lenses the IR camera can see a little green dot (the filter are not perfect and let pass some color ligth if is very strong), the same for the full-range, none of the two see the white dot which should be the IR, so my question is:
is it possible the glass can work as IR filter? I'm not saying replacing safety glass, but if works it can be used for a window or as an temporal o emergency protection (for a visitor or someone who wants to see the laser dot or something like that, first case that come to mi mind) for a non long expose.
I don't have the cameras with me rigth now but for tomorrow I can publish some photos if anyone interested.
Sorry if it was too much text.
Thanks.
