Abstract: An inspection device includes a light source emitting ultraviolet light onto a banknote conveyed on a conveyance path, a light source emitting infrared light onto the banknote, a photosensor for detecting light from the banknote, a light source control processing portion for controlling the light sources while individually switching the light sources at high speed, and a discrimination processing portion. The discrimination processing portion first imports each of two detection signals (output signals) from the photosensor, which are obtained by detecting light substantially within an identical period of time when the banknote is illuminated with the light through sequential lighting of the light sources and calculates an output ratio of the photosensor. Then the calculated output ratio of the photosensor is compared and collated with reference data preliminarily stored in a memory determining authenticity and denomination of the banknote.

Abstract: A chemical reactor includes two substrates that are joined along a surface and a chemical reaction chamber formed between the substrates. The chemical reaction chamber has a hollow interior and one or more light reflectors located along walls of the hollow interior. The chemical reaction chamber has one or more inputs to transport fluid into the hollow interior and an output to transport fluid out of the hollow interior. The one or more light reflectors cause light rays to make multiple crossings of the hollow interior as a result of reflections off the one or more reflectors.

Abstract: A gas sensor uses optical interferents in a porous thin film cell to measure the refractive index of the pore medium. As the medium within the pores changes, spectral variations can be detected. For example, as the pores are filled with a solution, the characteristic peaks exhibit a spectral shift in one direction. Conversely, when tiny amounts of gas are produced, the peaks shift in the opposite direction. This can be used to measure gas evolution, humidity and for applications for other interferometric-based sensing devices.

Abstract: An attenuated total reflection probe has a prism and a supporter. The prism is made of an optical material which transmits light in far ultraviolet region, and has a contact plane to be in contact with a sample, and an incoming plane and an outgoing plane both not to be in contact with the sample. The supporter has an opening and is connected hermetically with the prism around the opening and eventually exposes the contact plane facing the opening. The contact plane, the incoming plane and the outgoing plane of the prism are formed such that light transmitting the incoming plane enters the contact plane at an incident angle larger than critical angle and that the light totally reflected by the contact plane goes out through the outgoing plane.

The spectrometer is dimensionally stable over a range of expected ambient temperatures, without controlling the temperature of the spectrometer.
