LUMINOUS FLUX MATCHING DEVICE

摘要: PURPOSE:To provide the optical system which is unaffected by wavelengths of light providing a emitting part and photo detecting to spherical reflecting mirror placing in position where from through enters. CONSTITUTION:The an fiber LF1 being enters LF2 way concave faced M. The small diameter large radiation angle angle, these placed positions l1, l2 respectively may be totally entered adjusting distances l2. Since M has no factors such as refractive indices with case lenses, different matched, thus device usable for multiplex communication.
