A particle analyzer () includes: a light source that emits excitation light (EL) including light having a wavelength of 400 nm or less; a lens structure () that collects excitation light (EL) at a predetermined position () in a flow path (); a detection unit () that detects light (FL) emitted from a particle as the particle () flowing through the predetermined position is excited by the excitation light (EL); and a processing unit () that processes detection data acquired by the detection unit (). The lens structure () includes a plurality of lenses () arranged along an optical axis of the excitation light (EL); and a lens frame () holding the plurality of lenses (). At least one (G) of the plurality of lenses () is positioned in the lens frame () by abutting on a lens adjacent to the lens.

Particle analyzer, particle analysis method, and optical measurement device

An imaging optical system according to the present disclosure includes: an aperture stop; an image-forming optical system that causes an image to be formed toward an imaging plane of an image sensor; and an optical phase modulator that includes a substance having a birefringence index, and gives two pupil functions to the image-forming optical system. The following conditional expressions are satisfied:1≤(2××tan()+)/<1.4  (1)λ/4*0.75<Re<λ/4*1.1  (2), where

Imaging optical system and imaging apparatus

A rigid-scope optical system includes: an image-formation optical system that causes an image in each of wavelength bands to be formed in a predetermined imaging device, the wavelength bands including a fluorescence wavelength band and a visible light wavelength band; and a color-separation-prism optical system having a dichroic film that separates an optical path of light to be imaged into an optical path of the visible light wavelength band and an optical path of the fluorescence wavelength band, in which the image-formation optical system causes the respective images to be formed in a fluorescence imaging device and a visible light imaging device, the fluorescence imaging device and the visible light imaging device being disposed to cause an amount of misalignment to correspond to a difference between an optical path length of fluorescence and an optical path length of visible light.

Scope optical system, imaging apparatus, and endoscope system

The present technology relates to a display control device, a display control method, and a program enabling images to be checked in real time. A display control device includes: a receiving unit that receives small volume data that is information on current imaging by an artificial satellite; and a control unit that displays a live view image based on the small volume data on a display unit, wherein the receiving unit receives a satellite image corresponding to the live view image as large volume data at a timing different from that of the small volume data. The present technology can be applied to, for example, a satellite image processing system that processes satellite images captured by artificial satellites.
