Ronar-Smith® Beam Expander

Ronar-Smith® Beam Expander demands the highest quality in beam broadening and collimation without compromising on the expanded beam quality. We value safety as much as we do on the quality, and you can be assured that all our beam expanders are subjected to rigorous testing prior to market sales. All our beam expanders are telescopic by nature and require a collimated beam input while delivering an expanded collimated beam at the output.

What makes our beam expander products unique is the broad wavelength input that we carry and the customization services that we provide for customers who need specific requirements in their industrial and production line. The parameters that we are able to provide customization include wavelength-specific filtering, anti-reflection coating, magnification factor selection, input/output clear aperture, and maximum beam intensity.

Fixed Beam Expander (BEX)

Beam expander in laser system development is utilized for calibrating various elements. The diameter of the laser beam at the laser system output is adapted to the required diameter at the input of the objective lens. The beam expander is also primarily used in laser-material processes.

Fixed beam expanders are also designed for specific beam expansion applications such as laser engraving. They also feature anti-reflection coatings and high transmissivity to maximize the efficiency of the beam expansion and reduce losses. The disadvantage lies in the fixed magnification factor and applications that require tuning of the output beam size are unable to perform.

Manual Zoom Beam Expander (BXZ)

Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune manually to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required.

The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

Motorized Zoom Beam Expander (BXZ-MOT)

Motorized Zoom Beam Expander accounts for the short-fall of fixed beam expander by allowing the user to tune automatically to the required magnification factor, depending on various processes that is required. These beam expanders are also designed for high power applications where magnification adjustments may be required.

The concept of zoom beam expander works on the internal translation stages and focusing mechanisms to adjust and account for the changes in magnification continuously. It also takes laser divergence into consideration and performs relative adjustments without affecting the overall housing length.

CO₂ Beam Expander (UniBet & MiniBet)

UniBET series beam expanders are developed for higher power (>100w) CO2 laser without water cool. It has a consistent outer dimension and connecting thread M30x1.

MiniBET series are smaller in size, all have the same external diameter of 20mm, total range ranging from around 28mm to 70mm only. Thread M16x0.75 and it is widely applied in a compact CO2 laser system.

CO₂ Water Cool Beam Expander (BET-WC)

A laser beam expander is designed to increase the diameter of a collimated output beam. It is used in applications such as laser scanning, interferometer, and remote sensing. BET-WC Series water cool beam expanders are developed for even higher power (>200W) CO₂ lasers with consistency in outer dimension and water pipe connection.
