| 释义 | eyepiece noun[ C ] uk /ˈaɪ.piːs/ us /ˈaɪ.piːs/ the part of a piece of equipment, for example, a microscope, through which you look（显微镜等仪器的）（接）目镜 Physics: optics, microscopy & lasers anti-reflection anti-reflective chromatic aberration concentrator converging lens field glasses non-dispersive non-reflecting opera glasses optical density optics polarization polarize reflection reflective refract speculum mirror spotting scope spyglass transparency Bud wrenched away from the eyepiece. If the surface has periodic or irregular errors, no sharp image can be obtained, no matter how much the eyepiece may be moved in or out. Now if we push the eyepiece toward the mirror the same distance on the opposite side of the true focal plane, precisely the same appearance will be noted in the expanded star disk. Only one adjustment is necessary, and this is provided by means of the screws which fix the inclination of the eyepiece. The light, after passing through the lenses, is brought to a focus at the lower end of the tube, where the image is examined visually with an eyepiece, or photographed upon a sensitive plate. Examples of eyepieceeyepiece Drawings were made with the aid of a drawing tube, and measurements were made with calibrated eyepieces. This midpoint served as the beginning point and was positioned under a pointer in the microscope eyepiece. Measurements of worm lengths were obtained using a stereomicroscope with an eyepiece micrometer. Isolated follicles were measured with an eyepiece micrometer in a stereoscopic microscope. Isolated follicles were measured with an eyepiece micrometer in a microscope stereoscope. Relevant measurements were recorded through a calibrated eyepiece graticule and the data were compared with published species descriptions. The resultant digital image was subjectively similar to the real image viewed through the microscope eyepieces. All individuals that we caught with sweep nets were inspected with binocular eyepieces for t he occurrence of pollen. The length of the guard cells was also measured using a graduated eyepiece. The graduated eyepiece and field of view area were calibrated using a calibration slide. The endocardial thickness was measured using a graduated eyepiece at three sites for each histological section. To aid counting, an eyepiece graticule subdivided into 100 squares was used. For crustaceans, individual size was measured with a graduated eyepiece. Using a graduated eyepiece, we measured the endocardial thickness in samples from three sites in the left ventricle and one from the right ventricle. Measurements were taken from fresh material using a calibrated eyepiece. These examples are from corpora and from sources on the web.
