The Dual OWL 850/1300 is a handheld light source that is rugged yet affordable, especially since this one model does the work of two, coming installed with light sources for both 850 and 1300nm.The temperature compensated outputs are calibrated to couple -20dBm of optical power into multimode fiber.

The source is simple to operate with an intuitive 2-button interface, one button controlling power, the other selects the output wavelength. LED indicators highlight the selected source and verify that battery power is sufficient to maintain the calibrated output power. This unit is energy efficient, running up to 30 hours on one 9 volt battery
