摘要:
In a contact glass for ophthalmic surgery, which comprises a lens body (22) incorporated into a mount (37), said mount (37) having an anterior lens surface (29) designed to be placed on the eye (2), which anterior lens surface (29) is concave according to a curved surface (K), and an annular gap (44) is formed between the lens body (22) and the mount (37), via which gap a vacuum can be applied for fixing the contact glass (12) to the eye (2), it is envisaged that the mount (37) continues the curved surface (K) in an imaginary extension of the latter or at least does not protrude with respect to said curved surface.

For the microscopy of an object or a specimen with a combination of optical microscopy and particle beam microscopy, an electrically conducting specimen carrier (1) is used which is configured for use in a particle beam microscope as well as in an optical microscope and has at least one alignment mark (2). The alignment mark is configured as a pass-through structure and is detectable from the top and from the bottom of the specimen carrier.

An adapter to be applied in contact with an anterior corneal surface. The adapter includes a contact glass portion having a corneal contact surface curvature that is flatter than the undeformed anterior corneal surface. When the contact glass is applied the cornea assumes a deformed state corneal curvature that is parallel to the flatter corneal contact surface curvature. A mount portion circumferentially surrounds the contact glass portion and defines a suction duct that is structured to secure the adapter to the cornea by negative pressure when the suction duct is brought into contact with a surface of the eye surrounding the contact glass portion. The suction duct is partially defined by a peripheral edge of the mount that extends outwardly away from the mount portion and toward but not intersecting or extending beyond a geometric continuation of the corneal contact surface curvature.

What is described is an adapter for mechanically coupling a laser processing device to an object, said adapter comprising having a central region which can be moved into the beam path of the laser processing device, which beam path extends up to the object along an optical axis, and a peripheral region located outside the central region, said adapter being fixable to the laser processing device on the one hand and being provided so as to contact the object with its central region on the other hand, wherein fixing means are provided at the peripheral region, said means allowing the adapter to be releasably fixed to a receiving part of the laser processing device such that, upon application of a determined pulling force along the optical axis, the fixing means are removable from said receiving part.
摘要:
The invention relates to a contact glass for ophthalmic surgery. Said glass comprises a lens body that is held in a frame and a front lens surface that is designed to be placed against the eye. According to the invention, the front lens surface is concave and follows a surface curvature (K) and an annular gap is formed at the edge of the front lens surface between the lens body and the frame, said gap being used to apply a negative pressure in order to fix the contact glass to the eye. The frame is designed to follow the contour of an imaginary continuation of the surface curvature (K), or at least does not project beyond the latter.
