Use of low noise read-out - IC. For higher gain a regulation of bias voltage due to the temperature is to be realized. For very small signals stray light (noise source) is to be excluded by filters in order to improve the signal-noise relation. Avoid touching the window with fingers! Careful cleaning with Ethyl alcohol possible.
