    • The invention concerns an optical system which is adapted to take full-360° angle-of-view images from the surrounding scene or project images on the full-360° angles of view, and which has compact size, reduced flare light and high resolving power. The optical system comprises a front unit 10 having two reflective surfaces 11, 12 rotationally symmetric about a center axis 1, and a rear unit 20 that is rotationally symmetric about the center axis and has positive power. The front unit comprises a first reflective surface 11 located facing away from an entrance pupil 6Y and a second reflective surface 12 located facing away from the first reflective surface 11. The entrance pupil 6Y in a section including the center axis is disposed between the outer periphery of the first reflective surface 11 and the outer periphery of the second reflective surface 12. A light beam 2 incident from afar travels through the front unit 10 and the rear unit 20 in order, and is imaged at a position of an image plane 30 off the center axis. In the section including the center axis, the entrance pupil 6Y is positioned off the center axis, and in a section that is orthogonal to a plane including the center axis and includes a center ray of that light beam, a entrance pupil 6X is positioned on the center axis. The rear unit 20 comprises at least two groups.

    • A solvent for use in the preparation of an analytical sample includes at least one component selected from the group consisting of polyvalent alcohols, sugars, and hydrophilic polymers, and has a boiling point at one atmosphere of from 101° C. to 300° C. The solvent facilitates the preparation of samples for use in analyzing extremely small quantities in analytical devices having capillary channels. By virtue of its boiling point, the solvent can prevent the concentration of analytical samples without requiring special devices or tools, even when a minute quantity of sample solution is left for a long period of time or is placed in a high-temperature environment.
    • 用于制备分析样品的溶剂包括至少一种选自多元醇,糖和亲水性聚合物的组分,并且在一个气氛中的沸点为101℃至300℃。 溶剂有助于制备样品,用于分析具有毛细管通道的分析装置中极少量的样品。 由于其沸点,即使在少量样品溶液长时间放置或放置在高温环境中时,溶剂也可以防止分析样品的浓度而不需要特殊的装置或工具。
