The light from the teflon to the camera has two paths: (1) light bulb > teflon (back scatter) > camera. (2) light bulb > mirror > teflon (forward scatter) > camera. And the light from the mirror to the camera has two paths: WebGamma Scientific provides unique, high-performance solutions for reflectance and transmission testing. These reflectivity measurement devices and light transmission testing systems capture complete spectral and colorimetric properties of thin film coatings with scan times typically less than one second. the definition of negotiation of meaning
