Beam Expander - CO2 Laser
The most common type beam expander is derived from Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratio, the Galilean telescope is most often employed due to simplicity, small package size and low cost. Beam expander is commonly used to magnify the laser diameter to be focused back in smaller spot size.
CO2 BEX - Adjustable Series
BEX series of beam expander has been improved with adjustable mounting with connecting thread of M16x0.75, M22x0.75 or M30x1. This type of mounting has advantage as the internal lenses will only move along the optical axis without rotation. Adjustable ring with scales make it more convenient for user’s operation.

Advantages
This mount also has advantage as the first lens does not rotate in respect to the second lens. It also has been equipped with scale for the user to measure the distance of the lenses.

CO2 BEX - Fixed Series
The most common beam expander is Galilean type which usually has one negative input lens and one positive output lens, the beam expansion ratio for a Gaussian beam depends not only the specifications of the beam expender, but also on the laser beam parameters as well as the positions of the optical lenses.
