Abstract: An image-pickup optical system includes: a first lens provided near an aperture stop and configured to correct aberration; and a second lens arranged between the first lens and an image sensor and configured to collect light, the first lens being a gradient index lens. The degree of freedom of design of a gradient index lens is higher than that of a lens having a constant refractive index, and a gradient index lens thus has a high potential as a device for a lens. Because such a gradient index lens is employed, it is possible to correct aberration without performing expensive processing such as polishing for example. In other words, as a result, costs may be reduced and image-forming properties may not be reduced at the same time.

Abstract: To provide a technique that enables the risk of contamination to be reduced. Provided is a microparticle measuring apparatus including at least: a relay unit that enables a flow path through which microparticles flow and a cleaning fluid storage unit to communicate with each other; a sheath fluid tube that causes the flow path and a sheath fluid storage unit to communicate with each other; and a cleaning fluid tube that causes the relay unit and the cleaning fluid storage unit to communicate with each other, in which the relay unit includes a first connector that can be connected to a joint portion on the sheath fluid storage unit side of the sheath fluid tube.
