VIDEO CHECK ROLL PROFESSIONAL (VCR-P)
The VCR-P usually works like a videomicroscope with high performances but unlike this, is very compact, then it's easy transportable and can be placed on flat and curved surfaces. All its components work at 5V/12 V.
A primary characteristic of this new model is its particular cold light annular lighting system with high luminous power and its possibility to modify the intensity at a continuous scale.
This device is arranged to be easily removed (magnetic mount) and replaced with other lighting systems and accessories in examination. The possibility to change the source angle of the beam-light in 14 positions, allows to highlight very well also the smallest asperities and conformations of the surfaces under examination.
The possibility of being able to move on the surface under examination is guaranteed by a mechanical stage of high precision with microshiftings on X and Y axis up to 10mm.
Two fixed support rollers, covered with an anti-slip material, allow a good stability on cylindrical surfaces having a minimum diameter starting from 60 mm.
Magnetic rollers are also available for a stable placement on surfaces which allow it.
The available objectives with magnetic mount are included from 25X to 2350X (with reference to a 14" monitor), on request also special objectives with high resolution and big working distance (30 mm - 70 mm) are available.
The VCR-P can be connected to PC or laptop through its USB camera and the images can be captured, compared, measured, archived etc. with Video View Basic software.

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.
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||-|
|1100-CX||1380X||0.2 x 0.15 mm||-|
|1500-CX||1810X||0.15 x 0.11 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.
