A stereolithography apparatus () has an exposure arrangement (), comprising a radiative element (); a masking element (), having a substantially rectangular masking area (); an optical path () between the radiative element () and the masking area (), having a linear segment (); and an intensity-unifying arrangement (), having a first, a second, a third, and a fourth reflective surface () The first and second reflective surfaces (,) are arranged on opposite sides of the linear segment (), and the third and fourth reflective surfaces () are arranged on opposite sides of the linear segment (). In a cross section of the intensity-unifying arrangement () along any plane, perpendicularly intersecting the linear segment (), the reflective surfaces () follow a boundary () of a rectangle.

Stereolithography apparatus

A stereolitography apparatus comprises a fixed vat () or a holder for receiving a removable vat for holding resin during stereolithographic 3D printing, and a radiation source () for generating radiation capable of polymerizing portions of said resin in said vat. (). The apparatus comprises a shutter () between said radiation source () and said vat () for allowing only selected portions of the generated radiation to reach said resin, and a cooling channel () between said radiation source () and said shutter (). The apparatus comprises a blower () configured to force coolant gas through said cooling channel ().

Stereolithography apparatus equipped with shutter cooling channel

The invention relates to a dental imaging apparatus which includes an x-ray imaging means and at least one color camera for photographing the face of a patient positioned at the imaging station of the apparatus, which at least one color camera is arranged to image the patient's face positioned at the patient support station from different directions, and means arranged into functional connection with said at least one color camera for creating a virtual three-dimensional texture model of the patient's face.

Dental imaging apparatus

The invention relates to a dental computed tomography apparatus which includes an x-ray imaging means and at least one color camera for photographing the face of a patient positioned at the imaging station of the apparatus from different directions and at least one laser or a corresponding lighting arrangement, which is fitted to direct a light pattern at different locations on the face of a patient positioned at the imaging station, and a means arranged into functional connection with said at least one color camera for creating a virtual three-dimensional surface model from the light-pattern information directed at different locations on the face of the patient positioned at the imaging station, and a means for combining said face image information detected by said at least color camera to said surface model of the patient's face to create a virtual three-dimensional texture model of the patient's face.

Dental computed tomography apparatus

The invention relates to an imaging means ( ) suitable for recording images from the teeth and the mouth region. The imaging means ( ) comprise an image-recording device such as a video camera, the optical components of an object illumination system, an instrument connection cable and a connector. The invention further concerns a dental unit ( ) having one or more instrument connectors (C) onto which the control system of said dental unit ( ) switches the physical variables required for the use of the instrument attached to said instrument connector. The invention also concerns a method of connecting an imaging means to a dental unit.

The invention relates to a method and an apparatus for the adjustment of imaging values in a panoramic x-ray imaging apparatus. The imaging device comprises a CCD detector which is manipulated in such a manner that the domains to be imaged in an examined object are the first to fall in line with a serial register included in the edge of the CCD detector. The measuring information received from the serial register is used as preliminary information about an intensity received on the image field and this information is used as a basis for the adjustment of imaging values for optimizing the signal-to-noise ratio of the CCD detector.
