Abstract: Described herein are apparatuses for dental scanning and components of apparatuses for dental scanning. A component of a dental scanning apparatus may include a beam splitter, a transparency and an image sensor. The component may have a first surface and a second surface. The transparency may be affixed to the first surface of the beam splitter, and may comprise a spatial pattern disposed thereon and be configured to be illuminated by a light source of the dental scanning apparatus. The image sensor may be affixed to the second surface of the beam splitter, wherein as a result of the transparency being affixed to the first surface of the beam splitter and the image sensor being affixed to the second surface of the beam splitter, the image sensor maintains a stable relative position to the spatial pattern of the transparency.
