    hi, thanks for the response. This was a project for fun only. A verry low cost engraver, fast an cheap build (LD ~ 2€, Driver LM358 based, arduino clone 2€). i use a big and a fast CNC Engraver with a ~2W Laser for Wood Engraving (Pens and small wooden cans). China seller offers CDR-based...

    damaged Ophir 20C UAS-.5Y

    I suspected that .... does anyone have the circuit from the A-1-Y Head ? maybe a simple InAmp will help ... i will try

    damaged Ophir 20C UAS-.5Y

    i know .. but the connection is ok - and this circuit is reverse polarity protected (D2) ;-) the RS232 connection will not be established. i have tried this with a FT232RL (works on my other Ophir Head). No Communication .. only a unaccurate analog output

    damaged Ophir 20C UAS-.5Y

    measurement and phone with ophir support helps me a little (unofficially :-D) the only thing that is the same on all custom sensors with 6pin molex (95%) 1 - custom 2 - GND 3 - Vin (0.5 means that the sensor has clibrated 0.5V/1W - for 20W we need 10V + 2V => 12V, for 2W it is working with...

    damaged Ophir 20C UAS-.5Y

    ophir tells me .. the sensor with this serial number is a customer builded sensor (OEM). It is not a standard sensor. The RS232 protocol is unknown (no documentated ophir std protocol). No Information, No datasheet, No support (only for the first customer, but not me) With a own (std-)...

    damaged Ophir 20C UAS-.5Y

    hello, i have bought a used ophir 20C-UAS, but the sensor does not work. Its a 6-pin Molex connected module. I have contacted Ophir and they tells me, this is a NDA Sensor .. i cant get any informations about the interface or Analog-Output. i think .. this Sensor is damaged, but the...

    Possibly higher output diode

    hi, i have posted this diagram to help anyone. It is was measured by myself with my Ophir LPM. Informations for this laser diode are very rare and a i did not found a genuine datasheet. Greetings

    Possibly higher output diode

    ok .. i know, this is a old thread, but here is a testplot. max current is 83mA (i did not dare). 140mA ??? i dont belive :thinking:

    confused: two different datasheet about SLD3237VF(R)

    Hi, can anybody help ? What is the rigth datasheet SLD3237VF Datasheet (Page 2/2) | DatasheetLib.com or http://www.beamq.com/laser/laserdiode/sld3237vf_vfr.pdf the same layout and the same text, but different current and voltage many thanks
