View-through system

Space saving illumination system for double-side object inspection

Tech info
Resources

The View-through system is a unique space-saving illumination solution designed to illuminate two sides of an object. It consists of two symmetrical modules, each one made of two illumination units:

• A diffuse strobe dome illuminator (white color)
• A special active “view-through” backlight unit (white color)

View-through system is designed to create very compact inline inspection solutions that illuminate and image both sides of fast-moving objects. While one camera acquires the image of one side of an object, the corresponding dome and special backlight units emit light simultaneously so that one side of the object can be inspected. Subsequently, the dome and the backlight units are turned off so that the second camera can acquire the image of the other side of the object while its corresponding dome and special backlight units are now switched on. 

Such innovative approach can be achieved thanks to the special backlight units which act either as transparent windows (when turned off) or as backlights (when turned on), enabling to quickly and accurately inspect fast-moving objects almost simultaneously, in a very compact solution. 

The View-through system can be used for many different inspections, especially for identification of surface defects/features in applications spanning from automotive to pharmaceutical. 

The View-through system is available as LTVTA1-W, which consists of two dome units and two active backlight “view-through” units (white color) or as LTVTBENCH, a complete bench solution which additionally includes a base plate with two right-angle brackets, the LTDV6CH compatible strobe controller (programmable) and the ADPT001 RS485-USB adapter.

KEY ADVANTAGES

  • Compact space-saving solution for inspection of fast moving object
    Illuminates two sides of an object almost simultaneously.
  • Ultra-high power light output and strobe mode only operation
    For the inspection of fast moving object and extended LED lifetime.
  • Rugged industrial design with built-in industrial connector
    For easy integration with any machine vision system.
  • Modular configuration.

DESIGNED FOR OEM APPLICATIONS

  • Compatible LTDV strobe controllers available to easily power, control and synchronise LED illuminators.

Notes

  1. Measured at maximum current and maximum working distance.
  2. At 25°C. At max pulse width (1 ms), max pulse frequency = 15 Hz.
  3. At 25°C.

Ordering information

It’s easy to select the right illuminator for your application: our part numbers are coded as LTDMLAxy-WW where x defines the illuminator size (B = medium, C = large), y refers to the power intensity (1 = medium, 2 = high). For instance LTDMLAB2-WW is a diffusive strobed dome + low angle illumination system - medium size, high power, dome white, ring light white.
