The CoolCard™ II from Pathfinder Research (Lafayette, CO) is a handheld infrared laser beamfinder and beam evaluation instrument. The IR beam-quality evaluation tool can be used with lasers and other IR sources operating from the near-IR to 10-μm wavelengths. Using thermally- stabilized liquid crystal technology, the CoolCard™ senses and resolves the fine spatial character of lasers operating near and beyond 1.7 μm. The beamfinder features a rechargeable, field-replaceable Li-ion battery with capacity sufficient for multi-hour continuous operation.
