An optical device includes: a lock having a locking unit and an operation unit having at least a sensor; and a key configured to correspond to the lock. The key includes an unlocking unit having at least a light-guiding element for transmitting light between the operation unit and the unlocking unit. The operation unit is activated to unlock the locking unit after the sensor detects and recognizes the transmitted light. After encoding, the optical device of the present invention cannot be reproduced and the encoded light beam will not be intercepted and decoded easily so as to satisfy our security demands. Further, the structure of the optical device of the present invention does not decay easily. Therefore, the present invention has an excellent anti-theft effect and a reduced production cost.
