Abstract: An ergonomic microscope (1) and a microscope carrier (2) are disclosed. The microscope encompasses a stand (3) which possesses a stand base (3a) that defines an external contour (3b). The microscope (1) is placed onto the microscope carrier (2). The microscope carrier (2) comprises a body (4) and a left and a right hand rest (6). The left and the right hand rest (6) are attached to the body (4) so as to pivot freely and independently of one another.

Abstract: The invention discloses a substrate holder (8) that is configured to receive a substrate (20) and can be utilized to determine the thickness deviation of a substrate from the standard thickness of a specific substrate type. The substrate holder (8) comprises a one-piece frame having a flat upper surface (42). An opening (30) that defines a peripheral rim (32) is provided in the substrate holder (8). Receiving elements (34) on which spheres are provided are shaped onto the peripheral rim (32) of the opening (30). A substrate (20) placed into the substrate holder (8) thus comes to rest on the upper surfaces of the spheres. The support elements (34) are arranged on the peripheral rim of the opening (30) in such a way that they lie at the vertices of an equilateral triangle.

The baffle plate is arranged to enable the passage of air through the air inlet while occluding the emanation of light from the microscope through the air inlet. The baffle plate and heat sink are arranged to induce airflow through the baffle plate, across the heat sink, and out an air outlet for the microscope.

Abstract: An iris diaphragm device for a microscope includes an iris diaphragm having a stationary mount ring, a rotatable adjusting ring, and a plurality of blades. The plurality of blades form a diaphragm opening, which is steplessly adjustable, by rotation of the adjusting ring, between a maximum and a minimum opening size. A coupling linkage is connected to the adjusting ring and includes two levers. An actuation element drives the coupling linkage. A closure element is arranged on one of the levers in a way such that after a predefined size of the diaphragm opening has been established, a further actuation of the actuation element causes the closure element to pivot and cover the diaphragm opening.

Abstract: A method and an apparatus for laser microdissection of specimen regions (23) of interest of a specimen (4) are described. In a first step, an incomplete cut line (25) enclosing the specimen region (23) of interest is generated by means of a laser beam (7). At the incomplete point of the cut line (25), there remains a web (26) which joins the specimen region (23) of interest to the surrounding specimen (4). In a second step, the web (26) is severed with a single laser pulse directed onto it, thereby completing the cut line. The specimen region (23) of interest is in that context detached from the specimen (4) and falls by the action of gravity into a collection vessel (19).
