Optical print head using a glass arm waveguide |
摘要 |
This invention relates to an optical mechanism comprising: an optical beam generating mechanism to generate an optical beam; and a unitary, transparent waveguide for guiding the optical beam to an optically writable surface wherein optical elements for guiding the optical beam are coated onto the waveguide to create a relatively compact optical system, a relatively low exit numerical aperture for the exit pupil, and for bending and re-directing the optical beam.
