A general purpose high accuracy dosimeter reader, 80, for determination of a treatment condition, based on comparison of an image of treated dosimeter, 111, with a series of images of pre-treated dosimeter, 114, is disclosed. A dosimeter undergoes noticeable changes, such as a color change upon treatment with certain materials, such as toxic gases and processes, such as ionizing radiation and sterilization is pre-treated. The dosimeter is imaged with an imaging device, 115, such as charge-coupled device camera and images of the dosimeter or the changes, e.g., color change, are stored in an information storage device, 118. In order to determine the treatment condition, the treatment dosimeter is imaged and the image is compared with the series of pre-treated images of the dosimeter using software. The closest match of the treated dosimeter with the pre-treated and pre-imaged dosimeter would indicate the treatment conditions. The process and device can be used for almost any indicating device, process and treatment.

A CCD-based biochip reader includes a light source for emitting light beams, a collimating lens for converting the light beams into wide parallel rays of light, passing said wide parallel rays of light through a biochip and exciting fluorescence from fluorescent targets on the biochip, a focusing lens for focusing the fluorescence, a filter for filtering out said parallel rays of light, and a charge-coupled device camera for generating images from said fluorescence. For recording intensity of the fluorescence from the fluorescent targets, images of the charge-coupled device camera is converted into digital data through an image converting device. Wide parallel laser beams are produced by the laser and through the collimating lens, and excite all samples on the biochip with high efficiency at the same time. In addition, time for analysis is saved when fluorescent images of a large area on biochips are collected and analyzed through the charge-coupled device camera.

A controlling method for a CCD camera in which a photographing area is divided into a number of cell regions, the illumination of each cell regions is detected the photographing mode of a camera is switched to a daytime or nighttime mode on the basis of the detected illumination so that an optimum image is photographed even under conditions where the illumination of a certain position and the total illumination condition in the photographing place changes irregularly.

The microscope (S, 100) of the present invention has a hand piece (20, 112), whose tip is mounted with a thin sheet-like mirror unit (M, 10, 130, 220), and around both ends of the base (11c, 131c) thereof is arranged an illuminating light source (32, 117), whereby light is emitted to a target object, image light is lead through the light reception bore (27, 116), to the optical system (114), and is recorded at the CCD camera (111), to obtain video images. The thin sheet-like mirror (M, 11, 131) confines light and navigate it, wherein the width of the mirror can be made narrower like a convergent taper surface (11a, 131a); and it is comprised of a base surface (11c, 131c) where illuminating light comes in and image light goes out, and a mirror surface (11b, 131b) where illuminating light and image light go back and forth, and make the reflection thereof, and the mirror surface (11b, 131b) is slanted to 45 degrees. The microscope may be used as a handy microscope if it is not equipped with a charge-coupled device camera. The microscope can provide a wider horizon, which makes it possible to make a horizontal observation in an extremely narrow space, and can be manufactured at a less expensive price.

The invention relates to a substrate inspection device and a transmission illuminating device for the substrate inspection device. The substrate inspection device can prevent infrared light from an infrared light source from entering a camera without passing through the substrate, so that the substrate can be accurately inspected. The shape and arrangement of the infrared light source are set so that the field of view of the infrared light source of the charge-coupled device camera is covered by the field of view of the substrate of the charge-coupled device camera. Furthermore, by virtue of the Fresnel lens, the irradiation angle of the infrared light emitted from the light emitting diode element disposed near the edge of the infrared light source is deviated toward the edge direction of the substrate. In addition, the intensity of the infrared light irradiated from the infrared light source to the substrate on the edge region of the substrate is greater than the intensity of the infrared light on the central portion of the substrate.
