DO NOT UNNECESSARILY LOOK INTO THE TRANSMITTER LENS!

DO NOT UNNECESSARILY POINT THE TRANSMITTER LENS AT PEOPLES EYES!

The invisible laser radiation INSIDE the instrument may exceed the accessible emission limits of laser class 1, thus never open the instrument's housing  and never operate damaged instruments.

Aligning the infrared laser instrument LD90 with the lenses of CCD-cameras or infrared night vision devices can result in damage to them.

The LD90 is a Laser Distance Sensor which determines the distance to an object by means of transit time technique. It can be operated in the temperature range of -10 to +50°C. The maximum range is 2500m with an accuracy of 2.5cm. Frequency of measurement is ???
