Princeton Optronics, a developer of laser diode modules, has unveiled a laser-based illuminator that can be utilized with military night vision goggles and silicon cameras. The HPIL-3W808 at 808 nm measures 2x2x2 inches and has a 3 W output power. It is useful for illuminating long distances.
HPIL-3W808 Illuminator
The HPIL-3W808 device does not contain fringe and speckle and features an 18° beam divergence. It also has a custom configuration for less than 1° divergence. The unit has a wavelength spread of less than 3 nm FWHM, provides a 2-D array of light emitters, and generates a circular ray with random polarization. Wavelength drift of the device with temperature is 0.06 nm/°C.
The illuminator functions at temperatures ranging from -20 °C to 40 °C and does not need a cooling fan. It is ideal for combining with silicon cameras for cost-efficient night vision applications.
The HPIL-3W808 has a conversion efficacy of 40% with a slope efficiency of 5 W/A. The differential resistance is 1.5 Omega, operating voltage is 10 V, and operating current is 0.75 A. The threshold current of the HPIL-3W808 is 0.15 A with a continuous-wave output power of 4 W.
