What is the difference between red and laser barcode scanner which is better?

Release Time:2020-07-21

Barcode scanners are mainly divided into laser scanners and red light scanners (CCD), which are also widely used in our contact and teaching. Many customers will ask, Hongxing Yongli will tell you what is the difference between laser and red light of barcode scanners and which is better?

Barcode scanner red light and laser light comparison

The light emitted by the red light scanner is a very thick line (thick in the middle and thin at both ends). The farther the scanner is from the scanner bar code, the thicker the red light line, the lower the scanning success rate. Generally, the bar code should be scanned at close range with a red light gun. The laser scanner emits a very thin and uniform laser line. The reading ability of the laser gun is much stronger than that of the red gun. The laser gun can scan far away from the bar code. The laser scanner with good performance can even scan half a meter away, and the red light will not exceed 20cm as far as possible.

Comparison of the principle of red light and laser light emission of bar code scanner

Laser scanning head refers to the use of LASER laser luminescence principle, scanning width of up to 25cm;

The red light scanning head refers to the red light emitting principle of CCD, and the scanning distance is generally within 8cm;

1: resistance to fall

Laser reading head: not resistant to fall. Red Reading Head: Resistant to Fall

Note: Red light reading head is more resistant to falling because there is no moving part.

2: bar code reading distance

Laser reading head: 5-35cm. Red reading head: 3-25cm

Note: Generally speaking, because the light is easier to disperse, the red light reading distance is relatively close, and the laser basically does not diverge, so the reading distance is longer than the red light.

3: ability to read broken bar code

Laser reading head: weak. Red light reading head: strong

Note: The red light is generally one centimeter thick, so the sampling range is large. If the bar code is damaged, it will not affect the reading. The second laser is a thin line, so the damaged bar code is difficult to read.

4: Penetration reading capability

Laser reading head: strong. Red Reading Head: Weak

Note: Because the laser is not easy to diverge, so the penetration is strong, the general bar code is covered with plastic film, the effect of laser reading will be better.

5: dark light environment reading ability

Laser reading head: strong. Red Reading Head: Weak

6: strong light environment reading ability

Laser reading head: strong. Red Reading Head: Weak

7: Reading speed

Flat

8: Bit Error Rate

Flat

9: The Price

Laser reading head: slightly higher. Red Reading Head: Low

Remarks: little difference
