Does the Glass Block the Camera from Detecting the Light?

Some digital cameras have filters to block near-infrared light, but most can detect it. ... Near-infrared light passes through clear glass and will reflect off metal surfaces, including mirrors.

Can infrared pass through glass?

Infrared light is a form of electromagnetic wave consisting of longer wavelengths than that of visible light. ... Visible light will not be absorbed by the electrons in glass, so it shines through. Certain wavelengths of infrared light can also pass through glass, but many are blocked as their energy is absorbed.

What can block visible light?

Historically, we know that zinc oxide and titanium dioxide can block out visible light, but when micronized, they do lose this ability.
