Abstract: Improved colorimetric analysis of liquid samples is provided. A sample holder is used that delivers predetermined volumes of sample individually to each of several colorimetric test patches at the same time with a sliding action. An opaque housing is employed to prevent ambient light from reaching the test patches when color images of the test patches are acquired. Preferably, a mobile electronic device including a camera is attached to the opaque housing to acquire the images. Optical microscopy can be performed in addition to the colorimetric analysis.

Abstract: An imaging device including a light source; a two-dimensional image sensor that receives reflected light from a subject containing specular light of the light source and outputs an image of the subject; a light transmission member disposed in an optical path of light emitted from the light source to the subject; and a light shielding unit that, when a position on the subject at which light from the light source is regularly reflected and enters the two-dimensional image sensor is defined as a first specular position, whereas a position on the light transmission member at which light from the light source is regularly reflected and enters the two-dimensional image sensor is defined as a second specular position, shields the light directed from the light source toward the second specular position without shielding the light directed from the light source toward the first specular position.

Abstract: The present concept is a method of preparing an egg to determine the color of the egg using an egg yolk cover. The egg yolk cover is dome-shaped with a base edge and inspection area. The egg yolk cover eliminates ambient light from impinging on the egg yolk and is used in combination with a light sensor to determine the color of egg yolks. The light sensor includes a single flat printed circuit board with a top and bottom side which includes at least one LED light and one color sensor, at least one light pipe receiving light from the LED and transmitting it onto a substrate at an angle theta and a tube frame including an optical tube for receiving light reflections from the substrate. The light pipes and the tube frame are compression fit between the printed circuit board and a lower housing. To determine the color of the egg yolk, the egg is first cracked onto a flat surface. The egg yolk cover is then placed over the egg yolk and the color sensor is placed onto the inspection area to measure the color.
