In an analysis device that irradiates light from three or more light sources onto a cell, embodiments proposed herein prevent a reduction in the intensity of light from each light source, and are provided with at least a first light source, a second light source, and a third light source, and an optical system that guides light from the respective light sources onto a cell. The optical system is provided with a second light source optical element that reflects the light from the first light source and transmits the light from the second light source, and a third light source optical element that reflects the light from the first light source that has been reflected by the second light source optical element and the light from the second light source that has been transmitted through the second light source optical element, and transmits the light from the third light source.

An analyzer and a detection system are provided. The analyzer includes a chip placement structure and at least one detector unit. The chip placement structure is configured to place a detection chip, and the detection chip is provided with at least one detection area. The at least one detector unit is configured to detect one or more detection areas of the detection chip in a case where the detection chip is placed on the chip placement structure.

An apparatus to detect the topology of a workpiece including surface variations and flaws according to images from several viewpoints includes a frame, a loading member, a robot, an image capturing mechanism, and a controller. The loading member is positioned on the frame and loads a workpiece. The controller controls the robot to drive the image capturing mechanism to move or rotate to different preset positions from each of which the image capturing mechanism can capture images of the workpiece and transmit the images to the controller. The controller further processes the images to obtain an assessment of the components and surface of the workpiece for further processing.
