VIDEO CHECK ROLL-Z CX (VCR-Z CX)
High performant videomicroscope able to inspect flat and curved surfaces, completely in aluminium, it has an annular light system and a coaxial one with variable luminous intensity.
The VCR-Z CX series uses the whole range of objectives with magnetic mount of the VCR series, between 30X and 2350X.
Completely motorized, it can make microshiftings also at step of one micron thanks to a particular system of pilotage of the micro-engine.
This series comprises 2 kinds of videomicroscopes: VCR-Z CX and VCR-Z CXProfessional.
Unlike the VCR-Z CX (equipped with a X-Y mechanical stage for coaxial light and Stand Lite for annular light), the VCR-Z CXP is equipped also with a X-Y mechanical stage of precision for annular light; both of them are able to make microshiftings of 10 mm on X and Y axis.
With the X-Y mechanical stage for annular light is possible to use the professional illumination set which allows to change the source angle of the light in 14 different positions, on this way, the user can have a three-dimensional vision of the surfaces under examination.
Two fixed support rollers, covered in an anti-slip material, allow a good stability on cylinders' surfaces having a minimum diameter of 115 mm.
Magnetic rollers are also available for a stabler placement on surfaces which allow it.
The Video View Basic software allows the most common measurements, as well as the comparisons and the saving of the images in different formats.
The VCR-Z CX can be connected to PC or laptop through its USB camera.
The focusing in the VCR-Z CX system can be done in an automatic, semiautomatic and manual mode depending on the precision and the speed of execution you wish to obtain.
The VCR-Z CX series is able to move completely in automatic to look for a focus point, with high magnification objectives (from 750X upwards), 2-3 µm of precision and repeatability are reachable.
This feature allows to our VCR-Z CX videomicroscopes to measure with a very high accuracy the value of depth of micro-engravers or cracks on flat and curved surfaces of different materials putting the device directly on the surface to be analyzed.
The automatic system and of precision of the focusing establish the value of the Z axis making a difference between the top surface and the bottom surface with the relative image of the point where the focus has been found.
The possibility of using the VCR-Z CX is extended if combined with the Three Dimensional Explorer.

Practical example of employment of a VCR with PRISMS and STAND-UP
|Distance between the lighting
source and the plane
|Best working distance between a cylinder's surface and the lighting source (Ø min 115 mm)||Position the cylinder must have when it has a diameter less than 115 mm|
|Objects' maximum height if placed on a flat surface: 7 mm||Position of the rising supports (prisms) for the inspection of objects with height between 12 and 32 mm||Position of the prisms for the inspection of objects with height between 42 and 62 mm|
|Inspections of multilayered sheets or of very thin profiles through the use of prisms and magnetic STAND-UPs||Support (prism) for the inspection of small cylindric objects|
|For a correct illumination please refer to the following example|

|⇑⇑ Surfaces with Coaxial Lighting ⇑⇑|
|The lighting is supplied by a luminous source which is placed as a ring around the lens. The vision of the object through the lens gives a soft image as the rays are reflected and absorbed in different manners by the various surfaces.
This type of lighting is the most used one as it fits to a greater extent of surfaces of different materials.
|The lighting goes through the same axis of the lens.
The light comes perpendicularly on the surface of the object creating a hard image; this is due to the complete return of rays coming from flat surfaces and of those reflecting from slanting surfaces. This system is perfect to visualize engravings of metallic objects.

WORKING WITH "ANNULAR LIGHT PROFESSIONAL"
The possibility of inspecting any type of surface with all the wide range of available objectives of the VCR series (25X/2350X) and of the high definition series (LDH), will give a safe certainty to the operator to be able to use his device in almost all the occasions.
The difference between the set for annular light Professional and the annular light Lite one is the possibility, for the Professional, of selecting 14 different angulations of origin of the lightings around the subject so as to be able to search every particular and make the image visible and stereoscopic as in the example:
The use of the angulated light is suggested also to give prominence to the harshnesses or the conformation of the various surfaces.
