Laser beam expander
Laser Beam Expanders
Optogama designs and manufactures laser beam expanders to enlarge the diameter of laser beams (and reduce them as reducers) and optimize beam quality and focusing performance.
Optogama's laser beam expanders offer a wide range of options, including motor-driven, manually adjustable, fixed-magnification, and high-power models, catering to a broad range of applications from research and development to industrial use.
Furthermore, our unique mechanical design and high-precision optical design achieve high beam directivity stability, diffraction-limited performance, and high LIDT characteristics, enabling stable beam control even in high-power laser environments.
Product Selection
Optogama's laser beam expanders are classified according to differences in their variable magnification method, control method, supported power levels, and installation conditions.
When selecting a model, the main factors to consider are whether variable magnification is required (fixed/variable), whether manual or electric control is needed, the laser output level (standard output or high output), and the installation configuration (stationary or integrated into equipment).

- Want to change the magnification during the experiment? → MEX, VEX
- Emphasis on high precision and reproducibility → MEXimageV2, MEX
- High-power laser applications → MEX-HP, REX
- Simple and low-cost → VEX/VRE
- Equipment applications that do not require readjustment → FEX
- Spatial constraints apply → MEX-V
Technical supplement
A laser beam expander is an optical system that improves focusing ability and beam quality at long distances by increasing the beam diameter and reducing the divergence angle. There are two main configurations: Galilean and Keplerian. The former is compact and suitable for high power applications, while the latter allows for beam quality improvement through spatial filtering.
When selecting a beam, it is important to consider not only the magnification, beam quality, and collimation accuracy, but also the energy concentration at the intermediate focus and the damage threshold.
