DS Manual Scheimpflug Mountv3.Indd 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.

  • T-Mount - Wikipedia
    4/1/2020 T-mount - Wikipedia T-mount The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a T-mount male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric Type screw thread on the lens with a flange focal distance of 55 mm and a External diameter 42 mm mating female 42mm thread on a camera adapter or other optical component. This thread form is referred to as T-thread. (This Flange 55 mm should not be confused with the M42 lens mount which is also Connectors None 42 mm diameter, but has a 1 mm thread pitch. The T-thread is sometimes described as "M42x0.75," which is the usual manner in which to describe the thread.) The "T" is said to stand for Tamron or Taisei, a Japanese manufacturer that released in 1957 the first of a line of aftermarket camera lenses that fit 35 mm SLR cameras built by various manufacturers using their universal T-mount. On the first model, the mini T-mount used a M37×0.75 thread; Tamron's canonical M42×0.75 T-thread didn't appear on the market until about 1962. The company referred to it variously as a T-mount, T-thread, T-adapter, or a T-400, but not as a T-2, which is simply the name that Soligor used for its version of the T-adapter. The proprietary lens mount of each camera manufacturer was adapted to the T-mount thread with a simple adapter.

  • Lens Mount - Wikipedia, the Free Encyclopedia
    Lens mount - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Lens_mount From Wikipedia, the free encyclopedia A lens mount is an interface — mechanical and often also electrical — between a photographic camera body and a lens. It is confined to cameras where the body allows interchangeable lenses, most usually the rangefinder camera, single lens reflex type or any movie camera of 16 mm or higher gauge. Lens mounts are also used to connect optical components in instrumentation that may not involve a camera, such as the modular components used in optical laboratory prototyping which join via C-mount or T-mount elements. A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock (friction lock) type. Modern still camera lens mounts are of female lens mount of an Minolta XD-7 the bayonet type, because the bayonet mechanism precisely aligns with male mount of Minolta mechanical and electrical features between lens and body. Screw-threaded MC-Rokkor 58mm 1:1.4 lens mounts are fragile and do not align the lens in a reliable rotational position, yet types such as the C-mount interface are still widely in use for other applications like video cameras and optical instrumentation. Bayonet mounts generally have a number of tabs (often three) around the base of the lens, which fit into appropriately sized recesses in the lens mounting plate on the front of the camera. The tabs are often "keyed" in some way to ensure that the lens is only inserted in one orientation, often by making one tab a different size.

    15.10.2006 WAX-GG in 5 easy steps by Daniel Schweinert e-mail: [email protected] Material: Microscopic Slides – 76 mm x 26 mm x 1 mm (cut to 38 x 26 mm) Hard Paraffin Wax - 95 gramm (Paraffinum durum, Paraffinum solidum) White Bees Wax – 5 gramm (Cera alba) Jar Some clothespins Metal box Tape - 0.05mm thick (Scotch 3M or other tape between 0.05 – 0.10mm) Oven with “circulating air” 1. Turn on your oven and use “circulating air” at 100°C. Fill the jar with 95 gramm of hard paraffin wax and 5 gramm of white bees wax and put it together with the metal box into the oven. Close the oven and let the wax melt. (15-20 minutes) 15.10.2006 2. Prepare the microscopic slides. Clean the slides carefully with glass cleaner. Cut some tape strips (i used 2 for each side) and put it on the edges of the first slide. Place the other slide over it to create a sandwich with a gap of 0.10 mm. Fix the glass-sandwich with 4 clothespins (its better to use wooden ones because of the high temperature). 3. Warm Up the glass-sandwich! Now the wax should have melted. Fill it into the metal box and adjust the oven down to 70°C. Put the glass-sandwich into the oven beside the metal box to warm-up for 7 minutes. (this is very important otherwise the capillary action will not work properly if the glass-sandwich is not heated up) 15.10.2006 4.
