Specializing in products for use by the military, by Law Enforcement agencies and first responders, a key first focus of Battle Sight Technologies LLC is the building, testing and manufacture of a new prototype for the firm's pressure-activated chemiluminescent writing device. The pen-like instrument enables enhanced communication options in low-light and no-light conditions - a capability of consequence for many in populations served by the firm. MARC-IR is a pressure active chemoluminescent writing device that allows military special operators to write and mark walls in the infrared spectrum. The writing can be seen using night vision goggles in low-light and no-light environments. Leveraging technology licensed from the Air Force Research Laboratory's Materials and Manufacturing Directorate, MARC-IR was demonstrated and tested with a variety of military special operators and first responders during Tech Warrior OPS events in April and July 2018.
