Document Type and Number:
WIPO Patent Application WO/2023/002788
Kind Code:
A1
Abstract:
Provided is an objective lens (300) which is used in a sample analysis device (100) for detecting light in a plurality of wavelength bands from particles (P) flowing through a flow channel (C), and is provided in proximity to the flow channel, wherein the ratio of a converted optical path length L, which is obtained by converting the distance between a flow channel-side lens surface and the center of the flow channel to a distance in a dry system, to a focal length f of the objective lens in the dry system satisfies the following expression (1). (1) 0.15 ≤ L/f ≤ 0.45
