Lockheed Martin Aculight Capella-r 1850 Laser. This device has the Accession number 0612339. The Capella R-1850 is a Class 4 solid state diode laser product designed to emit 1850mn laser radiation at maximum pulse energy of 5 mJ (@1ms). The output port connects to a user-selected 200-600 micron diameter optical fiber. The Capella R-1850 is labeled in part: "***LASER APERTURE***Aculight Corporation 22121 20th ave SE Bothell, WA 98021***Feb 2007***Model R-1850, SN: 007***".

It has been determined that there are certain software driven operating sequences involving off-on cycling of the key-switch that do not result in a reset of the Stim Enable button, and emissions can resume after a standard 5 second countdown without pressing this button a second time.

On 11/22/10, Lockheed Martin Aculight sent a Memo to their Customers and Users informing them of the "Stim Enable" button reset error. The defect involves the function of the "Stim Enable" button on the front panel of the Capella R-1850. In December 2010, the firm sent a second lletter with instructions on how to return the Capella R-1850 Laser back for repair. The firm's plan to correct the defect involved removal of existing software, installation of revised software, and documented verification testing, per written instructions, to confirm resolution of the Stim-Emit button failure to reset. Corrections were to be made at no cost to the customer. A Lockheed Martin Aculight customer service representative will contact you shortly and provide detailed information on how to return the Capella-R 1850 laser product in your possession for testing and repair on this defect.
