VIDEO CHECK ROLL SPEED LIGHT (VCR-SL)

Video Check Roll Speed Light (VCR-SL)

This new videomicroscope has been designed to satisfy the requests of a lot of users of our VCR, desirous to have a simple tool, robust, easy to carry, not too expensive, to be given to your technicians for a practical and fast production quality checkboth inside your agency and outside by the customers.

The VCR-SL is the device which satisfies all these requirements, practical, compact, completely in aluminium, it has an excellent quality in the yield of the coloured images and it can also be easily linked to a laptop.

Its base is equipped with an annular lighting system at 12V at a very high adjustable luminous intensity which allows to inspect surfaces completely black or white also at 2350 magnifications.

It uses objectives with magnetic mount of the VCR series (from 25x up to 2350x) as well as the whole range of the available accessories for the same series.  

It is possible to use the VCR-SL on flat and curved surfaces and, thanks to its technical features, it is recommended also to inspect surfaces of cylinders engraved for the print from Ø 115 mm and upwards, included anilox cylinders or various polymers.

To let the VCR-SL adhere on cylinders or inclined metal surfaces, magnetic rolls with high attraction power are available.

The VCR-SL can be connected to a laptop or PC through its USB camera and, thanks to our Video View light software, it can make acquisitions, comparisons, archives, etc..

It's available the version with Video View Basic software to make also measurements.

If the VCR-SL is supplied with coaxial light, it takes the name of VCR-CX.

POSSIBLE APPLICATIONS

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
Use shims for small cylinders
  YES NO YES

ANNULAR LIGHT

Shaded parts
(no visible)
Luminous rays coming from an irregular surface
Lighted parts
(visible)
Reflected rays forming the visible image

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.

COAXIAL LIGHT

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.
