limit Photodiode wavelength


Is there a way for limit a photodiode to receive only wavelength in a specific range (for example: visible light 400-700 nm).

BPW 34 by OSRAM spectral range is 350-1100 nm


Put a filter in front of it.

where can i find a filter?

Try googling "optical filter". You're not completely helpless are you?

Amazon, E-bay, Aliexpress, your local photography shop... these things are really not hard to find.
