is TTL like having a digital input? like 100 different possibilities where as analog is infinite possibilities for input?To get the "full range" aka "white" you would need RGB, RGV gives a close match but not perfect. With the green being TTL you wouldn't be able to get the correct color match. all of your colors would have too much green in them.
Actually its the exact opposite:is TTL like having a digital input? like 100 different possibilities where as analog is infinite possibilities for input?
I see. TTL = extreme digital, only 0 or 1.Actually its the exact opposite:
An analog signal is used to control the intensity of the output beam. This signal is usually a voltage in the range of 0V to 5V. With an RGB laser and analog modulation you have, with an 8 bit system, 16.7 million colours at your disposal.
TTL modulation indicates that the laser does not support analog modulation of the output but only ON / OFF control. With an RGB laser and TTL blanking you have seven colours at your disposal. Red, Green, Blue, Cyan, Magenta, Yellow, White.
I guess it doesn't have to be, I already bought one of these though, Industrial TTL Green laser Module 50~60mW£>5¡«500mW green laser module£>Laser&lighting products£>www.0-like.comWhy must the green be TTL.. Depending on the power of the laser you might be able to use a FlexMod on it instead of the driver you're using now..
