Environmental adaptability:
1. Hot and humid: can withstand 20 cycles, every 24 hours, relative humidity 95%. The temperature varies from +30℃ to +60℃.
2. Fall: fall height (hard cement floor)1.7 meters
3. Hydrophobic: the optical outer surface has the characteristics of hydrophobic.
4. Anti-fog: The optical surface has anti-fog characteristics.
Reliability: Adjusting mechanism forward and reverse rotation 3000 times.
Structure requirements:
1. Paul-type optical structure, binocular handheld, can be used with the support, with probability to measure the target distance, azimuth Angle and high and low Angle function, eye distance adjustment range :56~72 mm
2. The active part should be smooth without stuck, and can stay in any position of the travel as required.
3. With a mobile phone fixing device, it can fix the mobile phone to take pictures at the eyepiece position.
4. With an air charging valve, the internal pressure of the mirror body should be maintained at more than 1 standard atmospheric pressure.
5. The shell material of the mirror body is salt spray resistant and corrosion resistant.
