Description: Listing is for a single Sharp 488nm GH04850B2G 55mW laser diode offered as either a bare diode or mounted in one of my high quality V5 12mm Copper modules with leads and your choice of copper back half and lens. SEE FULL TESTING DATA THREAD HERE Hollow Full Length Back Half Solid Full Length Back Half Solid Half Length Back Half Wire assignment is: Red + Black - A laser diode is a current-driven device which is should not to be driven by a voltage source. Otherwise electrical overstress may occur to the laser diodes as the operation voltage varies from device to device and additionally depends on the case temperature. Special care has to be taken, when switching the electrical power on and off, as transient currents beyond the maximum ratings can occur damaging the laser diode. To operate laser diodes correctly , a proper electrical driving mechanism has to be employed. A proper laser diode driver must be used to act as an accurate constant current source with good transient protection and very low noise. Connecting directly to a voltage source like a battery will destroy the laser. Warning there are many offers here on ebay for DC-DC converters and LED drivers sold as laser drivers which are very abusive to laser diodes and can significantly reduce the life or damage instantly laser diodes. Here is the Pinout for the diode Sharp 488nm GH04850B2G 55mW Laser Diode This is a 5.6mm Diode Datasheet These diodes fall between 486nm to 492nnm in testing of 12 diodes out of this lot. Wavelength Test Diode #1 486.8nm at 55 mADiode #2 487.4nm at 70 mA Diode #3 487.2nm at 55 mADiode #4 488.3nm at 130 mA Diode #5 490.3nm at 120 mA Diode #6 491.8nm at 100 mADiode #7 490.7nm at 80 mA Diode #8 487.6nm at 110 mADiode #9 486.9nm at 100 mADiode #10 490.0nm at 95 mADiode #11 490.2nm at 100 mADiode #12 490.8nm at 130 mA These results are specific to the SB308B292 bin which is the one I carry and can be confirmed by comparing the printed number on the top of the diode can as show below. If you source elsewhere be aware if this number is different the specs can be quite different. There are lower efficiency bins going around which are sourced at a discount and being offered as the same diode.
