Laser Beam Expander for UV light at 355nm, with 8X magnification, and adjustable divergence.
Beam expanders are optical systems used to increase or decrease the beam
diameter. The product of beam diameter and divergence of the laser beam
is a constant and therefore remains unchanged, i.e. increasing the beam
diameter means reducing the divergence of the beam to the same degree.
