If the minimum sensitivity for the first filter is arbitrarily chosen as one-tenth the dark counting period, which is in excess of three hundred seconds, the minimum detectable light intensity would be: .00858/30 = .000286 lumen per cm2. This is equivalent to an intensity of .256 foot-candle for a 30 second counting period.
