Should You Purchase A Video Inspection System Or Microscope?

microscope or video Inspection System

It can be a daunting task to choose the right inspection system for your application. Three types of inspection systems are generally employed for industrial applications. Let us a take a look at each one of them, along with their merits and demerits.

Video Lens Inspection System

This particular system comprises of single lens paired with an Analog/HDMI/USB camera attached to a computer or monitor. The system can either be built piece by piece or are pre-assembled and pre-configured like the Cyclops. A video inspection system can have a magnification range of up to 3000x.

Common Applications of the system include light assembly work at low magnification, high magnification, performing measurement and other evaluation when paired with USB Camera, and quality inspection and documentation.

Pros And Cons

  • In order to provide a wide range of magnifications, versatile systems can be configured in a number of ways.
  • Easy capturing of images, followed by evaluation when paired with USB camera.
  • When used in lieu of conventional microscope, it significantly reduces eye fatigue.
  • Perfect for any budget

There are some drawbacks as well for this video inspection system:

  • In comparison to a conventional stereo microscope, the 2-D only image significantly decreases field depth at higher magnification.
  • On pairing with USB camera, the image may lag on moving!

Stereo Zoom Microscope

It is certainly the most commonly used microscope in industrial applications. A stereo zoom microscope consists of two eyepieces for viewing with a magnification range of up to 200x, along with a main objective lens. The common applications of this technique include but are not limited to laboratory use, medical device manufacturing and soldering.

Pros And Cons

  • As a user, large working distances allow you to work with tools like cutters or soldering iron under the microscope.
  • Live three dimensional view and excellent field depth makes precision assembly easier.
  • It is cost efficient

Some of the drawbacks of the system include:

  • Digital Measurements and Image Capture is not possible.
  • Eye tiredness from constant use.
  • The magnification range is limited up to 200x

Trinocular Stereo Zoom Microscope Inspection System

It is exactly the same as the stereo zoom microscope, except that it has an additional 3rd port to support a camera for capturing images.  The camera can be directly connected to a monitor (HDMI, SXGA, VGA type cameras) or to a computer (USB types)

Some of the common uses include assembly applications where measurement or image capture might be necessary, without any requirement for constant 3D imaging with large field depth. Another application includes quality inspection where some rework, repair or assembly may be required.

Pros And Cons

  • Measurement and image capture capabilities when paired with a digital/USB camera.
  • 3-dimensional view visible working beneath the scope, along with added 2-dimensional screen monitor view that helps in reducing eye fatigue.

Talking about the drawbacks, it has a higher first cost than stereo microscope. When viewing on the Monitor, there is a loss of 3-dimensional depth of field.

To choose the right inspection system for you, you need to assess your comfort levels, budget allocation and specific application needs. Before you invest in a system, always carry out a thorough research and buy from an authentic source like Willrich.
