but i also want that these IR diodes must have a pointing beam , if i use 4-5 diodes n parallel will there beam be a pointing beam like red laser because the IR i have am using now have a pointing beam like red laser..so what will i do further in order to collimate that transmitted IR beams...
these are the specs of IR i am using, i have to increase its range upto 10m..so what should i do ,is there any circuit in which i connect it , i have already inserted a resistence of 46 ohm in order to operate it .
i have checked its data sheet and its photo-sensitivity (S) is upto 830nm ,so what do you suggest further.
where as i am using an IR of wavelength 980nm
@ Tpetar , i am working on continuous IR , although your suggested links helped me in making ma concept but the point is that will i get reflected IR beam same as red laser ,i mean in straight line because further i have to use this reflected IR beam on photo detector and then to amplify that...
I am working on second phase of this experiment , I have to use an infrared beam of 980nm .
Actually i am facing problem in detecting this IR , as IR is invisible to normal eye,
other is that what sort of circuitry should i use to detect the reflected IR beam from the target.?
kindly i need...
