LaVisionLaVision We count on Photons We count on Photons Scheimpfl ug The LaVision manual Scheimpfl ug mount version3 is designed for the adjustment of the angle mount between a camera and its lens (Scheimpfl ug angle). The Scheimpfl ug mount can be rotated in order to align tilt axis. The Scheimpfl ug angle is changed by tilting the camera lens with respect version3 to the sensor plane. Features large Scheimpfl ug angle up to 20° Scheimpfl ug rotation axis aligned with camera chip = image center does not move when changing the Scheimpfl ug angle free orientation of the camera for oblique Scheimpfl ug angles wide internal aperture for large camera chips very compact design Smaller cameras can be supported directly by the Scheimpfl ug adapter, to simplify the alignment for oblique angles. The Scheimpfl ug mount version3 is especially designed to be used in Tomographic PIV sys- tems, Stereoscopic PIV systems, StrainMaster 3D and other LaVision Imaging products, which operate with 2 or more cameras. Tomographic PIV or 3D StrainMaster systems often need large Scheimpfl ug angles from oblique viewing points. The Scheimpfl ug mount version3 allows maintaining Scheimpfl ug angles up to 20° from any camera orientation without signifi cant loss of light intensity due to its free space internal design. Even at largest angles the internal obstruction is reduced to a minimum. Highspeed cameras with their large CMOS chip dimensions profi t from the large internal aperture of the Scheimpfl ug adapter.

The camera’s image sensor is always planar and when it is placed in the image plane the whole image is in focus from the center to the rim. If the angle between object plane and optical axis is different from 90° (like in a stereoscopic setup or under oblique imaging conditions) the image plane is also tilted and an image sensor which is placed perpendicular to the optical axis sees a blurred image in areas where the sensor plane and the tilted image plane do not coincide. Therefore the camera needs to be tilted against the optical axis by this Free rotation around camera axis for Scheimpflug angle. oblique Scheimpflug angles Specifications Scheimpflug angle 0-20° to one side Camera orientation free orientation 0-360° around camera axis Lens mount f-mount, M42 lens mount (M42 × 1 internal thread) Camera mount c-mount, M42 camera mount (M42 × 1 external thread) Rear distance to camera chip 17.5 mm Maximum chip size 36 × 24 mm (Scheimpflug angle around long chip axis) (requires M42-mount camera) Mounting base 2 x M6 thread, 50 mm span Max. camera weight for direct support up to 2 kg (e.g. Imager Pro X series, Imager E-lite) heavier cameras must be mounted on the camera base, not on the Scheimpflug adapter Weight approx. 500 gr.
