Last time you asked me to answer the launch, Xiaohan received a lot of friends' advice. So Xiaohan did the following questions collection, and still by our Hanhai photoelectric Li Gong to do detailed answers for you.

Q：What is the service life of Hanhai photoelectric laser detector?

A：The service life of laser monitoring equipment of Hanhai optoelectronics is more than 10 years.

Q:Are there any vulnerable parts in the equipment of Hanhai optoelectronics? For example: laser head?

A：Without wearing parts, the semiconductor laser itself is very stable, and is installed in a high-strength stainless steel shell, will not be subject to any impact, so it is not easy to damage.

Q：Will the equipment be affected by the instability of voltage, current and other A:parameters? If not, why not? If it will be affected, how to solve it?

A：No, the equipment will carry out strict voltage fluctuation test according to the national standard before leaving the factory. The instability of voltage and current on site will not affect the equipment.

Q：Will the laser be affected by the sunlight?

A：No, the laser and sunlight of the equipment are two kinds of light with completely different wavelengths, and there will be no interference between them. Moreover, the equipment will also do direct sunlight interference test according to the national standard before leaving the factory to ensure that it will not be affected.

Q：Will the laser be affected and blocked by dust, metal and other debris?

A：The laser of the device is vibrated and propagated through the circuit tuning, which can penetrate the dust, haze and other environment. However, substantial obstacles such as metal, wall and so on will completely block the light path, and the device will be affected.

Q：Laser is produced by semiconductor sintering, so will it be affected by temperature? Such as extreme high and low temperature?

A：All parts and materials used in the equipment, including the laser, have a temperature range, which can meet the normal use in the temperature range of - 40 ~ 70 ℃. It is proved by the test results and test reports.

Q：Will the device suddenly turn off light?

A：can't. The lasers used in the equipment have been tested and verified in various extreme conditions, which can ensure long-term stable operation without light interruption.

Q：How much range can Hanhai optoelectronic's laser equipment monitor?

A：The product technology of Hanhai optoelectronics represents the height of national technology. Its fixed scanning mode can be used for radar 360 in the range of 300 meters ° Rotation scanning; The distance of fixed reflection detection can reach 1km.

Q：Coal mine passive laser sensor and detection emergency system detection range (area)?

A：The coverage area of a single sensor is 15 square meters.

Q：What is the detection distance of portable remote sensing laser methane detector?

A：Hanhai optoelectronics has launched two portable remote sensing laser methane detectors with detection distances of 100 meters and 30 meters respectively.
