PROBLEM TO BE SOLVED: To provide block optical element constitution used as a transceiver for a light detection and ranging (LIDAR) system. SOLUTION: This block optical element constitution is provided with a plurality of glass modules aligned each other as a block to form a plurality of optical paths in an inside, and fixed each other to maintain the alignment, a collimated light source for generating a coherent light beam on at least one of the optical paths in the block for guiding the coherent light beam to an outlet point of the block, and a light detector fixed onto the block. The block receives a reflected coherent light beam and transmits the reflected coherent light beam to the light detector through at least one of the other optical paths formed in the block.
