IR=800+ nm??? yes, IR. Those diodes all have three pins, one ground and one each for the laser diode itself and a monitoring photodiode which can be used to control closed-loop the laser. try www.farnell.co.uk for laser diodes in general and look for their datasheets. They have a huge library and the general data for such small power laser diodes ( power can be estimated by the laser warning label on the printer, the laser classes are specified by output power) should be quite similar independing of the make of the diode Jan -- Author: Jan Wuesten INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
