What Kind Of Rays Are Used In A Barcode Reader?

Most establishments that sell products and services use barcode scanners when processing payments.

Barcode scanners are one of the most common and important machines used in doing business today. 

Did you know that different scanners use different types of light rays?

It is important to understand the components of a barcode scanner especially the type of light rays it uses so you can understand how it works so you can provide proper care and maintenance.

Infrared Radiation

Infrared rays are electromagnetic radiation with wavelengths longer than those of visible light.

They are commonly used in barcode scanners as they are easy and convenient to use. Following is some of the features:

  • Easier readability by illumination. This means there is no need to flash bright red or white lights for the imager to read the code. It is not distracting nor annoying for users and customers.
  • It compensates for unpleasant and uncertain ambient lighting. Barcode scanners that use infrared rays do not need good lighting because it uses its own infrared source to flood the item being scanned with enough light so the code can be read by the imager. It does not matter if the room is dark or well-lit. The barcode scanner will work either way. Scanning will work no matter what the lighting situation of the room is.
  • It controls the illumination of the barcode. Establishments that use barcode scanners with infrared rays are usually equipped with infrared pass-through windows that will ignore other light variance. This means you have more control over how the subject being scanned will be illuminated as it appears on the imager.


Laser or moving beam scanners uses laser rays to read the code on the items.

It works by having a constantly moving beal element like a revolving polygon oscillating mirrors, holograms, or Micro Electro Mechanical Systems (MEMS).

Most laser scanners have a scan rate of at least 40 seconds. Most laser scanners today scan items in an instant.

It is fast and reliable and is very popular with grocery stores and shopping centres.

Led Lights

LED lights are used by CCD scanners also known as charged coupled device or non-laser imaging/illumination.

The reading head is equipped with hundreds of tiny light sensors and a and LED-based illumination source.

The LED-based illumination scanners were inspired by the new digital photography industry.

This is a more efficient and very affordable option for barcode scanners.

As a result, LED scanners are gaining more and more popularity today and are expected to become an industry-standard in the years to come.
