We’ve already talked about the amazing applications of laser rangefinders, but getting that perfect measurement requires winning a battle that happens on the invisible spectrum of light. If the 905nm wavelength is the speedy, cost-effective soldier , then the Short-Wave Infrared (SWIR) wavelengths—specifically the 1500s—are the heavy-artillery snipers . The main contenders here are 905nm versus the SWIR band, but within the SWIR family, a new tactical decision is emerging: 15
