VIDEO CHECK ROLL-Z Lite (VCR-ZLite)
It is a portable videomicroscope for inspections and measurements of cracks or engravings on flat and curved surfaces on X-Y-Z axis. Very robust, completely in aluminium, with interchangeable optics, it uses the same range of objectives and accessories of the VCR series. Unlike the VCR-Z series, the VCR-ZLite makes micrometrical measurements on Z axis with manual control focusing with high precision thanks to the help of a pilot mechanism in the microshiftings and the focusing software.
A digital millesimal comparator ensures an easy and immediate reading of the depth value (Z axis) obtained from the difference of focusing between the upper and the lower surface.
Connected to a PC or laptop through its USB camera and guided by our focusing software, step by step also the least expert users will be able to have a real reading of the values on Z axis. Automatic optics calibration.
The VCR-ZLite is delivered with a high resolution colour microcamera and an annular lighting system with adjustable high luminous intensity which allow to have on the screen high quality images that can be saved in more common formats.
Through Video View Basic software it is possible to make measurements in live, comparisons and storing of the images very easily. The software also allows you to make measurements on the saved photos, even after a long time and without any devices connected.
Thanks to its compactness, practicality of use (it works at 5V) and a reduced price, the VCR-ZLite becomes the ideal tool for the people who have to travel, being sure to have at disposal a reliable tool of precision to connect to the laptop.
If the VCR-ZLite is supplied with X-Y stand with microshiftings (10 mm), coaxial light set and annular light set, it takes the name VCR-ZLite CX; this version is advised for who want to do micro-graphics or to inspect and measure difficult surfaces as for example the depth of printing cylinder for rotogravure or anilox.
If you want to have a lighting source with possibility to illuminate the objects from different angles, indispensable to have the three-dimensionality of the objects or the visibility of some printed holograms, the VCR-ZLite Pro version is available.
Thanks to this configuration the system is able to solve almost all the requests of inspection of metallic and polymer surfaces.

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.

|- 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.
