ATAGO’s new polarimeter offers robust performanceand ultimate efficiency in small footprint.

POL 1/2

Thanks to improvements made in structural design, the POL-1/2 needs only half the space of a conventional model.
The space-saving design promotes installation flexibility.
A lightning-fast response time of 60° per second optimizes operational efficiency.
The optional Peltier temperature control unit delivers perfectly temperature-controlled measurements. This Peltier temperature control unit does not require the use of water.
