VIDEO CHECK ROLL CX (VCR-CX)
Small and compact videomicroscope, completely in aluminium, ideal to inspect flat and curved surfaces directly in the production cycle.
If used for the analysis of the surfaces of cylinders or rolls, its performances are exalted; it is mainly used in the check of the cylinders engravings in the graphic field as well as of materials in the metallography sector.
The VCR-CX supports two cold light lighting systems coaxial and annular. They are easily interchangeable, fed at 5V/12 V (like all the CX system), the issued cold light has a very high luminous intensity and is adjustable with continuous graduation in the annular system.
It can use all the optics with the magnetic connection of the VCR series (25X-2350X) plus a very high definition series, for particular applications.
A base full of precision mechanical stage with microshiftings on X-Y axis of 10mm guarantees an easy research of the target also for very high magnifications.
Two fixed support rollers, covered in an anti-slip material, allow a good stability on surfaces of cylinders having a minimum diameter starting from 60 mm with annular light and 120 mm with coaxial light; for lower diameters (up to 60mm) it is possible to use a different mechanical stage.
Magnetic rollers are also available for a steadier placing on surfaces which allow it.
The VCR-CX can be easily connected to a PC or a laptop through its USB camera and thanks to our Video View Basic software it can do measurements, comparisons, measurements and storage of the images directly.
For the using of the VCR-CX in particular applications, there are some stands available, which allow, opportunely equipped, to satisfy the most of the necessities.

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|

|Anilox roll (1000X)||Rotochalcographic
|⇑⇑ 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.
OBJECTIVES FOR COAXIAL LIGHT with Magnetic Mount
|Field of view||Maximum examineable depth|
|200-CX||225X||1.4 x 1.1 mm||15 mm|
|320-CX||390X||0.7 x 0.5 mm||-|
|475-CX||550X||0.5 x 0.4 mm||-|
|750-CX||950X||0.3 x 0.2 mm||-|

|2350-CX||2750X||0.1 x 0.09 mm||-|
|- The values reported on the tables could be lightly different (5-10%) due to the optical and mechanical unlike series.
- These objectives are usable also with VCR-CX PRO with annular light.
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.
