Abstract: An Information Handling System (IHS) display includes an integrated colorimeter that is stored within a front-facing bezel that borders one side of the display screen. The front-facing bezel includes hinged door that conceals a compartment housing a tray. The tray includes a colorimeter and is deployed from the front-facing bezel via the hinged door. With the tray deployed, the colorimeter is raised from the tray and positioned for measuring light emitted by the screen. The deployment of the tray from the front-facing bezel is along an axis perpendicular to the screen and the raising of the colorimeter from the deployed tray is along an axis parallel to the screen. The raised colorimeter may be positioned closer to the screen though movement of the tray along the axis perpendicular to the screen, thus reducing ambient light that reaches a colorimeter sensor of the colorimeter.

Abstract: In one embodiment, a flow cytometer is disclosed having a compact light detection module. The compact light detection module includes an image array with a transparent block, a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and a plurality of filters in a row coupled to a second side of the transparent block opposite the first side. Each of the plurality of filters reflects light to one of the plurality of micro-mirrors and passes light of a differing wavelength range and each of the plurality of micro-mirrors reflects light to one of the plurality of filters, such that incident light into the image array zigzags back and forth between consecutive filters of the plurality of filters and consecutive micro-mirrors of the plurality of micro-mirrors. A radius of curvature of each of the plurality of micro-mirrors images the fiber aperture onto the odd filters and collimates the light beam on the even filters.

Abstract: An optical measurement system includes a light source, a spectroscopic detector, a reference sample, a switching mechanism that switches between a first optical path through which a sample to be measured is irradiated with light from the light source and light produced at the sample is guided to the spectroscopic detector and a second optical path through which the reference sample is irradiated with light from the light source and light produced at the reference sample is guided to the spectroscopic detector, and a processing unit that calculates, by performing correction processing based on change between a first detection result at first time and a second detection result at second time, a measurement value of the sample from a third detection result provided from the spectroscopic detector as a result of irradiation of the sample with light from the light source at third time temporally proximate to the second time.

The first lens (111) and the fourth lens (114) have a substantially identical first focal length. The second lens (112) and the third lens (113) have a substantially identical second focal length. A first distance along an optical path from the first focal point (f1) to the second focal point (f2) is determined by a first predetermined condition.
