Abstract: A spectrophotometer for ascertaining transmission of enery by a test piece and having a housing with a source of energy in the housing and means carried by the housing for forming an image limiting aperture. Optical means within the housing is provided for receiving energy from the source for forming a beam of energy and imaging the source in the aperture. Means is provided for chopping the beam. Filter means is provided for passing selected narrow spectral bands of energy in the beam. Optical means is provided for receiving energy passing through the aperture and includes collimating means and means for causing the beam to be tilted at an angle with respect to the test piece. Means including a detector is provided for receiving the beam after it has passed through the test piece. In the method, a beam of energy is provided which is collimated and is offset at an angle with respect to the test piece so that back reflected energy is substantially eliminated and will not influence the tests being made on the test piece. Tests are made with and without the test piece in the beam.
