Beam Expander - CO2 Laser 9.4/10.6 um
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 Beam Expander - Adjustable Series
This series of beam expander 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. It has common connecting thread of M24x0.5, M33x0.5, M16x0.75,M22x0.75, M30x1.
Specifications:
-. For collimation of CO2 laser
-. Fixed magnifications 1.5x-8x
-. Adjustable divergence
