Machine Vision Lyte-MV - Global Laser - #9

Text version of the page

S5. Modulation. The Lyte MV range of lasers has two options of modulation avaliable these are Analogue modulation and Digital TT modulation. Version: Analogue (A) - Intensity control function This function allows the user to adjust the output power via the control lead, it is linearly controlled from the maximum factory set power to off. Power adjustment chart 0 V = Off 1 V = Max Power - Modulation & Synchronization The laser may be modulated or synchronised to the camera by using an external signal. (Voltage range 0 to 1Vdc) Frequency Range of Lyte MV and Lyte MV Excel = DC to 200KHz * Frequency Range of G reenlyte MV Excel = DC to 10KHz * Please note: Intensity control and modulation functions may be used together. * = Measured at 90% modulation depth, sine wave to -3dB Version: Digital (D) The Digital TTL driver board allows the unit to be gated on and off, or pulse-width modulated at TTL voltage levels via the control lead. Two versions are available either non-inverting TTL or inverting TTL. For non-inverting 2 V = on and vice versa for the inverted model.
