UNAVCO Summary of Optech ILRIS-3D

Retired October, 2012. No longer owned by UNAVCO

The ILRIS is a long range scanner (up to ~1500 m) and was UNAVCO’s first TLS instrument, acquired in 2008. We specially outfitted this scanner for cold weather deployment and it was a tried and true instrument for polar applications. It was deployed in non polar environments as well.
