In order to use this product safely, please read this instruction carefully before operating this product
●This laser imager is a precision optical mechanical product. Failure to operate according to the regulations may result in dangerous laser injury. Do not open or adjust any part of the laser photometer, or attempt to repair or adjust the performance of the laser photometer.
●Pay attention to electrostatic protection: The electronic parts of the laser photometer are electrostatic discharge sensitive equipment. Do not touch any electronic equipment without protective measures.
●Turn on the laser photometer power for operation only within the specified voltage and power range.
●Do not touch the optical lens with your fingers or hard objects (to prevent grease contamination or scratches).
●Do not measure high reflectance targets at too close a distance (to prevent damage to detector core components).
●Do not store under non-specified conditions (high pollution environment, beyond storage temperature range, etc.).
●The laser photometer shall not be subjected to strong mechanical impact (vibration, impact, fall, etc.).
Do not expose the laser photometer to sudden temperature changes (> 3℃/min) (to prevent lens cracking).

The STA-1064100M medium laser photometer (hereinafter referred to as the laser photometer) is a precision photoelectric product which transmits the laser to a specific target and calculates the distance information according to the laser flight time. It has the characteristics of outstanding performance and simple operation. The laser photometer belongs to the eye safety products, through the serial communication.
1.1.The main composition of laser photometer
Laser photometer is a precision photoelectric integrated product, and its main composition is shown in Figure 1:

1.2 The main functions of the laser photometer are as follows:
●Laser ranging function and real-time reporting distance value;
●Power polarity reverse connection protection, overcurrent and overvoltage circuit protection function;
●Can output laser light synchronization signal;
●Can report the current working temperature in real time, for the host computer to judge and calculate;
●Laser out times reporting function;
●Power on and power off control;
●With a single ranging, continuous ranging function;

Table 1 specifies the insulation resistance values of the measuring points

◆External logo (including product number) should be fixed firmly, clear, complete and easy to identify.

After the laser imager is started, the laser pulse with a periodic frequency of 1Hz is emitted, which reaches the measured target through the transmitting antenna. Most of the beam is absorbed or diffusely reflected by the target, while a very small part of the beam returns to the receiving antenna and converges on the detector module. The detector module samples the reflected signal and obtains the distance information of the measured target through an algorithm.
Examples of calculation:
Measurement time (one round trip) =10us
Propagation time (one way) =10us/2=5us
Ranging distance = Light speed × travel time =300000km/s×5us=1500m

Atmospheric visibility has a great impact on the ranging performance of laser photometer. Please refer to Figure 2 for the ranging capability of this product in different visibility.

Figure 2 The relationship between the ranging ability of laser photometer and atmospheric visibility

The laser rangefinder uses a laser source in the band of 1064nm. When using the laser in this band, it is necessary to avoid the outgoing beam directly into the human eye as far as possible to prevent human eye injury.

The mechanical interface of the laser photometer consists of 3 through holes, which are fixed to the installation platform by 3 M5 screws. The dimensions of the mechanical and optical interfaces are shown in Figure 3 below.
