My little kid likes to press buttons too much, so I'd like to protect a shelf with my HiFi equipment with a door from acrylic glass (PMMA). My only concern is: Would I be able to practically use IR remote when the sensors are behind acrylic glass?
I've found this information on Wikipedia:
PMMA passes infrared light of up to 2,800 nm and blocks IR of longer wavelengths up to 25,000 nm. Colored PMMA varieties allow specific IR wavelengths to pass while blocking visible light (for remote control or heat sensor applications, for example).
Does it mean that plain transparent PMMA will pass beam from IR remote or I need some special coloured variation? I don't know what is the typical wavelength or IR remotes and I don't have any spare acrylic glass pane to just try it.
