LBE-10 Laser Beam Expander

[Features]
· A beam expander that can expand the laser beam in simple experiments.
· Collimating adjustment has been performed to achieve the optimal collimated state when the collimated beam is incident, allowing the collimated light to be easily magnified simply by directly emitting the laser beam.
· The optical system of the beam expander has an air gap structure that does not bond lenses.
· This makes it possible to also use high-output lasers.
· By using the Galilean type lens composition, the number of aberration correction lenses has been reduced and the total length of the beam expander has been shortened.
· The visible light type can be attached directly to the exit port of the He-Ne laser (05-LHP-111/121/151/171/991/925).
· A beam expander holder (LBE-H) is available, where a beam expander is inserted in a holder which has been equipped with minute tilt adjustment.
· * When a beam expander is placed inclined to the optical axis, beams emitted from the beam expander will be inclined from the optical axis.
· * Arrange with light vertically incident on the beam expander, or adjust the angle of the beam expander with a tiltable holder.
· * Beam expanders cannot be used in the reverse direction to function as beam diameter condensers for creating collimated light.
· * Calculate the divergence angle of the laser beam and the position of the beam waist, and use an appropriate optical system accordingly.
· * The output beam may not collimate if the incident beam is divergent or convergent light.
