Abstract: A photoionization detector (100) comprises an ultraviolet radiation source (130); one or more detector electrodes (204 and 205); and a shielding material (206) located between the ultraviolet radiation source (130) and the one or more detector electrodes (204 and 205), wherein the ultraviolet radiation (240) does not directly impinge on any part of the one or more detector electrodes (204 and 205). A method for gas detection comprises exposing a photoionization detector (100) to an environment containing a target gas; and shielding the one or more detector electrodes (204 and 205) from direct impingement from the ultraviolet radiation (240) via the shielding material (206).

Abstract: Improved wafer-scale testing of optoelectronic devices, such as CMOS image scan devices, is provided. A probe card includes an LED light source corresponding to each device under test in the wafer. The LED light sources provide light from a phosphor illuminated by the LED. A pinhole and lens arrangement is used to collimate the light provided to the devices under test. Uniformity of illumination can be provided by closed loop control of the LED light sources using internal optical signals as feedback signals, in combination with calibration data relating the optical signal values to emitted optical intensity. Uniformity of illumination can be further improved by providing a neutral density filter for each LED light source to improve uniformity from one source to another and/or to improve uniformity of the radiation pattern from each LED light source.
