Motorized Zoom Laser Beam Expander / BEZM-1/8-1030/1100

• The installation direction assumes the mounting surface is down.
• A 4-axis Alignment Stage/TLF-5085 is available for optical axis alignment.

• When used with a high power laser or near a light source that produces high heat, the lens may become hot and the focal length may change.
• Lenses are made of synthetic fused silica only and are not corrected for chromatic aberration.
• Use shutter control or other means to prevent laser light from incident on the product during magnification change.
• Please handle cables with care. Impact, compression, bending, twisting, tension, etc. may cause the cable to break.
• When reducing the beam diameter, the laser energy density at the small aperture (exit aperture) may exceed the laser damage threshold (*1) of the lens and break the beam expander.
• If the beam expander is used in the opposite direction (beam reduction direction), the desired effect may not be achieved. Please refer to the Laser Beam Expander Technical Note for details.

※Laser pulse width: 10ns, repetition frequency: 20Hz
