A particle measurement system using a single component light collecting system with an aperture having a portion within direct view of the light detector. An aperture assembly extending into a sample may be self-concealing by having an extended portion to block light from directly illuminating the light detector. Alternatively, a smooth, reflective inside surface of the aperture assembly provides for self-concealment by causing spontaneous emitted light to have low angles of reflection. In either case, spontaneously emitted light is substantially prevented from reflecting directly into the light detector, thereby reducing light noise to the level of molecular noise.
