Abstract
The present invention aims to provide a composite optical device which includes the day-time optical device, thermal imaging optical device, laser application device and displaying device while reducing the volume and weight, further comprising attenuator that can control the amount of light for easy display on the display. The present invention also aims to provide a composite optical device with enhanced efficiency of transmitting laser and easy operability by installing the attenuator at an appropriate location. To attain the object of the invention, the composite optical device for day and night time sighting and measuring distance, having a laser application device, a day-time optical device, a thermal imaging optical device and a display, comprises a laser transmitting optical device comprising a beam shaping lens 120 for shaping and sighting the laser emitted from a laser source 110, a focus lens 130 installed in front of the beam shaping lens 120 for controlling the emitting angle of the laser, and a folding mirror 140 installed in front of the focus lens 130 for reflecting the laser passed through the beam shaping lens 120 and focus lens 130 to a first beam splitter 270, a…
