Since green absorbs red,…
Not entirely accurate. When a material or a filter appears green, it does not necessarily mean that it absorbs the red, it’s definitely possible that it reflects the red light. Look at the images below, this is a bandpass filter (transmitting range: 450-640nm) I’ve used, which is a type of interference filter. Obviously, the color of this filter appears different color when viewed from different directions/angles of light.
What said that ‘green absorbs red’ may be referring to an absorptive filter, which block a certain band of wavelengths by absorping them. The most common used absorptive filters are color glass and absorptive neutral density filter.
acrylic transmits IR
Not entirely accurate. Transparent acrylic can be designed to transmit visible light but block infared light. See this video or this product of MidOpt as examples. (Note that the second example is exactly a green transparent acrylic as you’re interested.)
That correct?
It’s possible. But it depends on the specific transmitting spectrum of your ‘green transparent acrylic’. Because [a normal, uncoated acrylic] + [green and transparent] these two conditions are not sufficient to determine its actual spectral transmittance. As @SolomonSlow commented, it’s a complex topic.
I’m not sure about the specific composition of the ‘green transparent acrylic’ you mentioned, but I suggest you purchase professional filters to meet your needs.
