Features

• A beam expander that can expand the laser beam by simple experiments.
• Since the collimation is adjusted so that the best collimated state is obtained when the collimated beam is incident, it is easy to obtain the enlarged collimated light by directly injecting the laser beam.
• The optical system of the beam expander has an air gap configuration without gluing lenses together.
• This allows it to be ***d with high-power lasers.
• The Galileo lens configuration reduces the number of aberration correction lenses and shortens the total length of the beam expander.
• The visible light type can be directly attached to the exit port of the He-Ne laser (05-LHP-111/121/151/171/991/925).
• A beam expander holder (LBE-H) with a beam expander built into the holder with fine aori adjustment is available.
• * When the beam expander is placed inclined to the optical axis, the beam emitted from the expander is inclined to the optical axis and emitted.
• * Position the beam expander so that it is perp***icular to the incident beam, or adjust the angle of the beam expander with a tiltable holder.
• * The beam expander cannot be ***d in the opposite direction to produce collimated light with reduced beam diameter.
• * Determine the divergence angle of the laser beam and the position of the beam waist, and *** an appropriate optical system.
• * If the incoming beam is divergent or convergent, the outgoing beam may not be collimated.
