How to specify a lens to increase angular responsivity of optical sensor? Sensor I presently use has angular responsivity +/-60 degrees at 50% level and I would like to increase it to +/- 80 degrees at 50% level or more.
Which lens should I use?
Please advice on design guidance for this procedure.
PS: (Angular responsivity = Angle of acceptance =~ sensitivity of sensor to light arriving from different angles)
