Beam Expanders

Fixed beam expander (BEX)

• Fixed beam expanders are designed for specific beam expansion applications such as laser engraving. They also feature anti-reflection coatings and high transmissivity to maximise 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)

• The zoom beam expander accounts for the short-fall of the 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 the 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.

Motorised beam expander (BXZ-MOT)

• The motorised 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.

CO2 beam expander (UniBet and MiniBet)

• UniBET beam expanders are developed for higher power (>100W) CO2 lasers. The MiniBET series is smaller in size, all have the same external diameter of 20mm, total range ranging from around 28mm to 70mm only.

CO2 water cooled beam expander (BET-WC)

• 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.
