The present invention relates to a microscope (10) including an objective lens system (30) and a zoom system (32). Furthermore, the microscope has a stop (60) for limiting the aperture of the optical path. Furthermore, a control unit (64) is provided which, depending on the current ...
Medical Definition iris diaphragm noun : an adjustable diaphragm of thin opaque plates that can be turned by a ring so as to change the diameter of a central opening usually to regulate the aperture of a lens (as in a microscope) Love...

It forms an incomplete diaphragm between the anterior and the posterior chambers and regulates the amount of light entering the posterior portions of the eye. • The color of the iris varies among species, within species, and even within the same animal. Heterochromia is a different color ...
The iris acts as a diaphragm to regulate the amount of light entering the eye. The two iris muscles are innervated separately: The parasympathetically innervated sphincter muscle is responsible for constriction of the pupil, and the sympathetically innervated dilator muscle causes pupillary enlargement....
(f′ = 75 mm) and a pinhole diaphragm with a diameter of 8 mm. A specific stimulus (glass/chromium mask with fully opaque features of 200 μm) was placed in the conjugated plane and its image was directly projected on a CMOS color camera (DCC1645C from Thorlabs) for further ...
The components of the diaphragm may be a plurality of blades which are rotatably mounted at a circumferential portion of the diaphragm, wherein each blade of the plurality of blades is rotatable towards the center of the iris. The blades of the plurality of blades may comprise a first synchro...
4.1. Iris–Lens Diaphragm Devices The first posterior chamber prosthetic iris device was inserted in 1991 by Sundmacher [10,31]. These lenses consist of a rigid iris–lens diaphragm with a peripheral opaque annulus and IOL style haptics that function as an artificial iris. They have a large ...
