Cercis Model 520L Universal Reference 904 nm Laser is a handheld instrument used to simulate a pulsed laser for testing of target acquisition devices. It includes eight user-selectable modes-1, 2, 3 kHz and External up to 10 kHz, plus MILES (Multiple Integrated Laser Engagement Systems) Codes 0, 27, 29 & 30.  Six energy levels  are selectable-17.5, 22, 28, 34, 38 & 43 mErgs, and the user may adjust energy output from 1 mErg to 100 mErgs (~0.1 nW to 10 nW).  The user can select word sequences (1, 2, 4, 8 or 16 words), and set trigger  to send MILES codes in ~1 second intervals.

     A diffusing adapter, designed to fit over a domed detector, includes lenses which diffuse the modal scattering of laser output and focus the beam onto the device under test.  A  detachable FC:FC multimode fiber jumper is included. 

  Cercis provided this Fiber Optic Range Tester (FORT) for testing a target acquisition system.  It has four user-selectable lengths - 500, 1000, 2000, and 4000 meters, which can simulate ranges up to 1000, 2000, 4000 and 8000 meters, respectively.  There is an USB interface for computer or remote control, and a 670 nm red visible laser that can be used for alignment of the collimator to the free-space laser source or for optical  component inspection or detection  of fiber micro-bends or breakage. 

  There are two collimators-which can be used interchangeably for laser input or bypass port output-provided with the FORT.  These include a helical focuser which can be set for use with various-wavelength lasers.  The collimators include a 2" (50 mm) diameter coated lens.  An FC optical port provides connection to an FC connector jumper. 

  The FORT illustrates the capability for Cercis to integrate fiber optic components with embedded systems, to meet the spec requirements of a customer.  Please contact us by phone (609-737-5120) or email (info@cercis.com) to discuss your application.

Multi-Laser Source for PD Lifetesting
Cercis Multi-Laser Light Source is a custom CW 10-mW 1300 nm 12-laser source used for Automatic Power Control (APC) Testing for InGaAs photodiodes.  The unit has an interlock, plus each laser has on/off switch and FC/PC connection. This unit is used for burn-in testing (200C, 24 hrs at 10mW power input) by a leading manufacturer of high speed photodiodes.  The 1300 nm lasers are coaxial-pigtailed; all lasers are thermoelectrically cooled.   Cercis can customize the unit by changing laser wavelength(s) or optical power output, to suit customer requirements.
