ABSTRACT:
An improved strobe lamp holder is formed of a member with a semi-circular appearing, trough-like, reflective curved inner surface in the direction of the axis of the member. Covering the light emitting opening of the lamp is a light diffusing material. Covering the open ends of the trough-like curved surface is a light confining material. The holder is adapted for placement of a strobe bulb inside the trough-like curved surface, diffusive material and light confining ends is a strobe bulb. The improved strobe lamp holder is adapted to emit light rays in a predominantly rectangular pattern with the length of the rectangle oriented perpendicular to the axis of the reflecting curved surface. The improved strobe lamp holder is designed for use in centrifuge measurement of liquid production into or out of mineral cores. The improved holder confines, orients, condenses, uniforms and emits the light from a stobe bulb in a uniform, high intensity, rectangular pattern, thereby enabling measurements in a single flash with improved accuracy and resolution.
