The HawkEye IR-7x Series is a MEMS technology pulsable infrared emitter. This source is based on patented technology. Due to its low thermal mass, the IR-7x Series can be pulsed at frequencies up to 70+ hertz with good modulation depth (contrast between the on and off states).
The IR-70, mounted in a TO-39 header with a windowless cap provides the smallest package and gives the widest output energy beam. FWHM (full width at half max) for the IR-70 is 100°.
The IR-75 is an IR-70 emitter with a collimating optic to provide approximately 15x the on-axis output. FWHM (full width at half max) for the IR-75 is 15°.
Also see the Universal Photon Source (UPS) Driver Board as an accessory to your emitter.
