An example article may include an optical filter and a multilayer stack adjacent the optical filter. The multilayer stack may include a plurality of layers. Each respective layer of the plurality layers may define a respective window edge of a plurality of window edges. The plurality of window edges may define an optical window configured to transmit light through the optical filter. At least a first respective window edge of the plurality of window edges may be stepped relative to at least a second respective window edge of the plurality of window edges.

An imaging system includes an imaging device configured to image an imaging subject on an imaging optical axis, and a calculation unit configured to acquire data relating to a position and/or a size of the imaging subject based on image information acquired by the imaging device through the imaging. The calculation unit acquires change information relating to condition change in the imaging and/or change in the imaging subject on the image. The change is caused by interposition of a light transmitting member when the light transmitting member is interposed on the imaging optical axis during the imaging, and the calculation unit corrects the data based on the change information.

The present invention relates to provide, among other things, the methods, devices, and systems that can simply and quickly collecting and analyzing a tiny amount of vapor condensates (e.g. exhaled breath condensate (EBC)).

An imaging system includes a mirror and an imaging device. The mirror includes a body and a conical hole formed in the body. An inner wall surface of the conical hole is a conical mirror. The imaging device faces a first opening of the conical hole and captures an image of a product in the conical hole. A light from a side surface of the product is reflected by the conical mirror to the imaging device and the imaging device captures a side surface image of the product.
