Anti-reflection colored film-coated glass products prepared by forming on a transparent glass substrate with a refractive index of 1. The butt stock has a cylindrical recess with key grooves longitudinally therein for receiving the slot and key cylinders. In an embodiment of the present invention the cleaning solution also contains a surfactant. Further, the enhanced image is returned. The apices continuously sweep the inner wall creating cavities of successively increasing and decreasing volumes with associated fluid inolet and exhaust port. One of the irradiance incident on the at least one test specimen from the reflector device and the temperature of the at least one test specimen is adjustable by movement of selected mirrors from the first operative position to the second operative position in response to an input in order to control one of a temperature of the at least one test specimen or the irradiance.
