<p>PURPOSE:To decrease the number of parts, and to simplify the assembly by using a frame body for housing an optical lens, as the housing part of an electro-optical element, as it is, and also, fixing it by other optical lens housing frame body. CONSTITUTION:An optical lens 21 is housed and stuck in an optical lens housing frame body 23, and an optical fiber 22 is connected to this lens. In the recessed part of the inside of the optical lens housing frame body 23, an electro-optical element 27 which has stuck a polarizer 25 and an analyzer 26 to both its sides is installed. Subsequently, other optical lens 28 is housed and stuck to other optical lens housing small frame body 29, and thereafter, inserted into the optical lens frame body 23 into which the optical lens 21 and the electro-optical element 27 have been inserted, and the electro-optical element 27 in which the polarizer 25 and the analyzer 26 have been formed as one body is fixed to an end face 30.</p> |
