38mm Laser Beam Enhancement Components

Motorized Variable Laser Beam Expander: MVBE

Motorized Variable Beam expanders collimators can be used to either expand or reduce the laser beam diameter. The MVBE has a variable  1X-4X expansion range providing precise beam expansion control via RS232 interface. A proprietary 5 lens-element design with 3 lens groups is used to reduce the internal focusing effects for high power applications.

MBVE Design

Other beam expanders contain 4 lenses consisting of 3 lens groups, the first being positive followed by a negative group then a positive group for collimation. This design causes a focus into the second lens group, consequently increasing the possibility of damage to the system.

• Diffraction-limited design
• 5 element design reduces internal focus
• Mechanical design minimizes beam wander
• Continuous zoom and focus adjustments

At Haas Laser Technologies, we employ a proprietary 5 lens-element design with 3 lens groups to reduce the internal focus. We use fused silica lenses on the two input groups. As a result, our zoom beam expanders tolerate a very high damage threshold.
