摘要： A non-contact type tonometer is disclosed. It includes a fluid discharging device for discharging a fluid from a nozzle towards an eye to be tested and transfiguring the eye, an eye pressure measuring device for measuring the eye pressure of the eye based on the pressure of the fluid, and an alignment detecting device for detecting the aligning state of the nozzle of the fluid discharging device. It further includes an eye pressure value correcting device for correcting an actually measured eye pressure value obtained by the eye pressure measuring device based on an alignment error information of the nozzle with respect to the eye using the alignment detecting device.

摘要： An optical illuminating and observing apparatus having a first drive system for changing the magnification of the apparatus and a second drive system for changing the illuminating field of the apparatus. The two drive systems can be operated either in an interlocking relationship or independently of each other. In a preferred embodiment, a clutch-gear is used to connect and disconnect the two drive systems to or from each other.

摘要： Method for determining a refractive index of an object in which the object is illuminated with a slit pattern of illumination light to form an optical section of the section of the object and the optical section is observed in two directions to determine apparent thickness of the optical section in these directions. Operations are carried out to obtain the refractive index of the object from the apparent thickness of the optical section.
