Abstract: There is disclosed herein a reference system for a fluorometer designed to detect very low levels of materials tagged with fluorophores. There is also disclosed an optical system for use in such a system which improves the signal to noise ratio. The reference system utilizes pulsed arc light excitation which excitation pulses are directed onto a flow cell containing the fluorescent dye. Fluorescent light emitted from the dye is guided to a photomultiplier tube which converts it to electrical pulses. A portion of each excitation light pulse is guided by a light pipe onto a PIN diode light detector which converts these light signals to electrical pulses. A LED reference light source is pulsed to generate a plurality of reference light pulses one of which occurs between each excitation pulse. A portion of each of these pulses is guided to each of the two light detectors and two more series of electrical pulses are generated. A microprocessor then reads the four electrical pulses resulting from each pair of light pulses and performs a computation on the resulting numbers which indicates the relative concentration of the target concentration being assayed. The optical system makes the excitation light pulses and the emitted light pulses to minimize the amount of scattered excitation light that gets into the emitted light optical channel and to control the location and size of the image projected onto the photomultiplier tube to stabilize its output signal. The light pipe and an output lens spatially integrates the image of the excitation light mask and focusses this light on the PIN diode so that the dancing image of the arc does not wander off the face of the PIN diode and destabilize its output signal. The action of the flow cell fluid contents spatially intergrates the fluorescent light thereby helping to stabilize the output of the photomultiplier tube.
Abstract translation: 本文公开了一种用于检测用荧光团标记的非常低水平的材料的荧光计的参考系统。 还公开了一种用于这种提高信噪比的系统中的光学系统。 参考系统利用脉冲弧光激发,激发脉冲被引导到含有荧光染料的流动池上。 从染料发出的荧光被引导到光电倍增管,将其转换成电脉冲。 每个激发光脉冲的一部分由光管引导到PIN二极管光检测器上,PIN检测器将这些光信号转换成电脉冲。 LED参考光源被脉冲以产生多个参考光脉冲,其中一个发生在每个激励脉冲之间。 这些脉冲中的每一个的一部分被引导到两个光检测器中的每一个,并且产生两个更多的串联的电脉冲。 然后微处理器读取由每对光脉冲产生的四个电脉冲,并且对所得数字进行计算,这表明所测定的目标浓度的相对浓度。 光学系统使得激发光脉冲和发射的光脉冲最小化进入发射光通道的散射激发光的量并且控制投影到光电倍增管上的图像的位置和尺寸以稳定其输出信号。 光管和输出透镜在空间上对激发光掩模的图像进行空间积分,并将该光聚焦在PIN二极管上,使得电弧的跳舞图像不会从PIN二极管的表面漂移并使其输出信号失稳。 流动池流体内容物的作用在空间上整合荧光,从而有助于稳定光电倍增管的输出。

Abstract: A flaw detector for optically transmissive surfaces having a first light collector above the surface and a second light collector below the surface. A scanning light beam is directed into the first light collector through a beam entrance aperture and only light scattered from the surface is collected. Light specularly reflected from the surface exits the collector through the beam entrance aperture. Similarly, light passing through the surface enters the second collector, but the axial beam component is dumped through an opening in the second collector, while only diffracted light is collected. Preferably, two-stage light collectors are used with the first stage admitting the beam and generating a scattered or diffracted beam component, with the second stage admitting the scattered or diffracted beam component and integrating the component over a collection surface and sampling the integrated portion at a photoelectric detector. An electrical output signal from the detector may be displayed.

Abstract: The present invention provides a far-infrared light source capable of reducing the shift in the location irradiated with far-infrared light even when the frequency of the far-infrared light changes. A far-infrared light source according to the present invention is configured so that the variation in the emission angle of far-infrared light in a nonlinear optical crystal when the frequency of the far-infrared light changes is substantially offset by the variation in the refractive angle of the far-infrared light at the interface between the nonlinear optical crystal and a prism when the frequency of the far-infrared light changes (see FIG. 8).
