Abstract
A laser riflescope includes a laser emitter, a laser receiver, an objective lens group (11) for collecting the visible light from the target to be measured, an eyepiece group (14) adapted for observation by the user of the distance information of the target and defining an optical axis with the objective lens group, a prism group (12) disposed between the objective lens group and the eyepiece group for light beam transmission, and a display element (13) for displaying the distance information of the target. The display element is an OLED having high transmittance to enhance the display brightness of the laser riflescope.
Claims20
A range measuring device having an observation optical system, the observation optical system comprising:
- an objective lens element collecting the visible light from the target to be measured;
- an eyepiece element adapted for observation by the user of the image and distance information of the target, the eyepiece element defining an optical axis with the objective lens element;
- a prism element disposed between the objective lens element and the eyepiece element for transmitting the visible light beam from the objective lens element to the eyepiece element;
- and
- a display element for displaying the distance information of the target, the display element being in the form of a light emitting element having high transmittance to enhance the display brightness of the range measuring device.
A range measuring device comprising:
- a light emitter emitting an invisible light beam to the target to be measured;
- a light receiver receiving the invisible light beam returned back from the target;
- an objective lens element disposed proximate to the target end;
- an eyepiece element disposed proximate to the observation end for observation by the user of the distance information of the target, the eyepiece element defining an optical axis with the objective lens element;
- a prism element disposed between the objective lens element and the eyepiece element for light beam transmission;
- and
- a display element disposed on the optical axis for displaying the distance information of the target, the display element being in the form of a light emitting element having high transmittance to enhance the display brightness of the range measuring device.
A laser riflescope comprising:
- a laser emitter emitting a laser beam to the target to be measured and aimed at;
- a laser receiver receiving the laser beam returned back from the target;
- an objective lens element disposed proximate to the target end;
- an eyepiece element disposed proximate to the observation end for observation by the user of the distance information of the target, the eyepiece element defining an optical axis with the objective lens element;
- a prism element including a front prism for receiving the light beam from the objective lens element, a rear prism for transmitting the light beam to the eyepiece element, and an auxiliary prism;
- and
- a display element disposed on the optical axis for displaying the distance information of the target, the display element being in the form of a light emitting element having high transmittance to enhance the display brightness of the laser riflescope.
