For large area (diameter) or diverging laser beams, Scientech 100 mm and 200 mm diameter disc calorimeters are ideal. Available in both surface and volume absorbing models, these calorimeters can handle both cw and pulsed lasers with average power levels to 100 watts and peak pulse power fluence levels to 100 GW/cm2. These calorimeters have found extensive service in scientific research, measuring single pulse energy levels to 1 kilojoule, in measuring laser range finders and Lidar systems, and measuring laser diode arrays and metal vapor lasers. These calorimeters will operate with the Vector indicators with an interface module (see below).

100 mm AND 200 MM DISC CALORIMETER INTERFACE MODULES FOR INDICATORS
Part Number	Description
10735	Interface Module for 100 mm Calorimeter Hookup to Vector Indicators for power and energy readings up to 30 W, 30 J
10747	Interface Module for 200 mm Calorimeter Hookup to Vector Indicators for power and energy readings up to 30 W, 30 J
10748	Interface Module for 100 mm Calorimeter Hookup to Vector Indicators with 10X electrical attenuator. The indicator will display 1/10 the actual value thereby allowing readings up to the calorimeters maximum power and energy capacities
10769	Interface Module for 200 mm Calorimeter Hookup to Vector Indicators with 10X electrical attenuator. The indicator will display 1/10 the actual value thereby allowing readings up to the calorimeters maximum power and energy capacities
