markIR 35TM	Demonstration Kit
Tuned Band Infrared Source                                                        FEATURES: · Viewing distance: 150 meters · Rejection ratio (inband/outofband power): 100 · Spectral output band: 2-6µm · Continuous/Pulsed operation: ~ 0/1 Hz · Battery operated: BENEFITS: · No detectable near infrared (<2 µm) · Invisible to night vision goggles (Gen. 3) · 10-16 hours operation (CR123 battery) · Low power consumption · Minimal thermal signature Description: The markIR Tuned Band Emitter uses a two-dimensional photonic crystal structure to tune and confine the IR emission to the spectral region of interest. This device has two elements capable of being powered together (in series or parallel configuration) or separately. Each 1.5 x 3 mm element has a resistance of 150 ohms and requires 3V and 20 mA to operate. The IR spectrum from the markIR 35 devices is shown in the optical characteristics graph. The markIR 35 demonstration kits contains 1 markIR device mounted on a circuit board and packaged in a standard housing. The switch contains three settings, pulsed (P), continuous (C), and off (O). The next generation of markIR devices will utilize wafer-level packaging to achieve a more compact package. [A long wavelength markIR is in development for use in the 8-12 µm region.] Applications: The tightly controlled emissions spectrum of the markIR 35 is ideal for operations where detection only by specific types of equipment is desired. Ø Personnel/unit identification Battery powered >1 night cycle Ø Cargo/pallet markers Battery powered >1 night cycle Ø Vehicle IFF Vehicle powered Extended operation Ø Landing zone markers Battery or mains powered Extended operation The markIR units can be operated individually or in combination to produce single or multiwavelength emitters in the mid- or long infrared portions of the spectrum. markIR units can be operated in the pulsed mode to extend the operational life of battery powered systems.
