Comparison of Advantages and Disadvantages of Bar Code Scanning Gun Laser and Red Light

Release Time:2020-07-21

The advantages and disadvantages of bar code scanning gun laser and red light are compared. Which of the two scanning guns is better? You should know how to choose after reading the following excellent comparison, or consult Hongxing Yongli online customer service, and she will recommend you with the appropriate scanning gun model according to your needs.

1. luminescence principle

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;

2. 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.

3. advantages

1. Laser bar code scanning gun

1) The laser scanning gun can be used for non-contact scanning. Under normal circumstances, the laser scanning gun is the only choice when the reading distance exceeds 30cm;

2) The density range of laser scanning bar code is wide, and it can read irregular bar code surface or read through glass or transparent adhesive paper, because it is non-contact reading, so it will not damage the bar code label;

3) Because of the advanced reading and decoding system, the first reading recognition success rate is high, the recognition speed is faster than the light pen and CCD, and the bar code recognition effect is good for the poor printing quality or fuzzy;

4) The bit error rate is extremely low (only about one-third of a million); the laser scanning gun has good shock and fall resistance.

1. Red bar code scanning gun

2, the price is cheap, the scanning light is relatively coarse, and the actual use has a better user experience.

4. Disadvantages

The price of the laser bar code scanning gun is relatively high, but from the sum of the purchase cost and the use cost, the laser scanning gun and the red light scanning gun are not much different.

The scanning distance of the red bar code gun is closer, and there are some requirements for the color of the bar code, such as the bar code can not be printed in red.

Laser bar code scanning gun is a variety of bar code scanning gun in the price is relatively high, but it can provide the highest scanning function index, so it is more widely used in various industries. However, most of the time, you don't need to pay too much attention to the price and brand when choosing a scanning gun, because due to the influence of market competitiveness, the price of the laser scanning gun has also been impacted to a certain extent, and the market price line fluctuates sharply, ranging from a few hundred to more than 1,000. So only need to choose the most suitable for their own use of the price of the scanning gun can be, regardless of laser or red light.
