OPTICAL DEVICE FOR OBSERVATION AND AIMING IN DAY AND NIGHT

摘要

The present invention provides an optical device for observation and aiming in day and night, which allows to use a military or civil optical device for observation and aiming in night time as well as day time. The optical device for observation and aiming in day and night of the present invention comprises a body having a lens group therein, and a first coupling part toward a user side based on the optical axis direction; a day time eye contact part having a second coupling part combined to the first coupling part; and a night time eye contact part having a third coupling part combined to the first coupling part in replacement of the day time eye contact part, and having a video amplifier. The first coupling part includes a first separation prevention part installed on the outer periphery of the body and preventing separation of the day time eye contact part or the night time eye contact part, and multiple first insertion protrusions installed on the outer periphery of the body at constant intervals; the second coupling part includes a first engaging groove inserted into the first separation prevention part, and multiple first insertion grooves inserted with the first insertion protrusions; and the third coupling part includes a second engaging groove inserted into the first separation prevention part, and multiple second insertion grooves inserted with the first insertion protrusions.;COPYRIGHT KIPO 2014
