IR Detector Question

  1. Nov 9, 2011 #1
    IR Detector Question....

    If someone take an IR sensor and puts a red covered piece of plastic over the sensor.....is that really going to significantly affect the performance?

    A friend of mine has a laser detector for road use and it appears to have a red plastic cover over the IR sensor...

    Police operate at 904 nanometers.....is a red plastic cover really going to improve the performance of the IR sensor by acting as a type of "filter"?

    I'm having a hard time believing this....
