But cost is higher.
The content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of rational in infrastructure, applied widely
The range-finding telescope of the optional emission source of model.
In order to realize above-mentioned purpose of utility model, the utility model employs following technical scheme：
A kind of range-finding telescope of optional emission source, including two imaging optical paths, a receiving light path and two transmittings
Light path, an imaging optical path include the first object lens, the first prism and the first eyepiece set gradually, and another imaging optical path includes
The second object lens, the second prism and the second eyepiece set gradually, a transmitting light path includes first transmitter and the first transmitting converges
Poly- lens, and the first object lens and the first prism are shared with imaging optical path, another transmitting light path includes lens, the second transmitting convergence
Lens and second transmitter, the receiving light path includes receiver and receives plus lens, and shares the second thing with imaging optical path
Mirror and the second prism.
Preferably：The receiving light path is additionally provided with benhain prism and compensating prism, and is coated with compensating prism point
Light film.
The utility model installs the light source of two different wave lengths as transmitter on a range-finding telescope, can be one
Meet the different demands of client on individual instrument.When only needing the data of short-distance and medium-distance using 905nm all the way as transmitting, hair
Emitter launches the laser of 905nm wavelength, enters prism group, objective lens, homed on its target object via plus lens；Need into
When row is tested over long distances, using 1550nm transmitter, via plus lens and lens homed on its target object.By imaging optical path pair
Distant object carries out aiming positioning, finally calculates the distance of tested object with receiving time difference and the light velocity according to transmitting.This
Utility model is rational in infrastructure, and using flexible can meet the ranging demand of middle and long distance.
