collimating optics Receptor arm in position

The radiation apparatus comprises a source carrier body, a collimator, and a collimator fixing bracket.

The invention further relates to said rake collimator as such and to a combination of a gamma detector and a rake collimator.

The collimator directs radiation to scintillator segments having apertures substantially matched to collimator apertures.

A collimator (112) collimates (616) the light.

The first collimator element has a first curved end.

The method includes developing the secondary collimator having a first collimator element.

An apparatus and method for coupling a fixed-aperture collimator to a variable-aperture collimator.

Above the substrate surface (4) a collimator (13) with equidistant rectangular collimator plates is arranged.

The off-focal collimator is preferably disposed between the radiation source and a primary beam collimator (24).

One such device is a collimator with a collimator shield for reducing noise when measuring radiation.

A first irradiation is made, during which the first collimator will define the outer edge of the irradiation pattern, and the second collimator will serve to narrow the effective width of each leaf of the first collimator.

The jaws act on the lugs (46) in order to detach the collimator from the sheath while at the same time seizing the collimator.

The collimator has very homogeneous absorption behavior even if the walls of the collimator elements are very thin.

At two ends of the optical fiber collimator, two optical fiber adapters are partially embedded in the optical fiber collimator.
