Hello community,
I am thinking to purchase IR led and detector (attached datasheet).
Is there any way to filter out all frequencies but one coming out IR LED,
I know it is impossible to achieve single digit frequency, it will be more of band of frequencies.
This IR LED peaks at 940 nm, its Spectral bandwidth (Δλ) is 30 nm.
I want 2 output bandwidth
1) Δλ -10 nm peaking at 920 nm and
2) Δλ -10 nm peaking at 940 nm
My second question is for PT333-3C photo transistor which will serve as detector.
Its detection spectral Bandwidth is 400 nm to 1100 nm peaking at 940 nm
as far as i can see it will detect both bandwidth easily.
