    Abstract: A shutter assembly includes a first shutter blade having a first toothed arm extending therefrom and a first light transmitting aperture therein, and a second shutter blade positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm extending therefrom and a second light transmitting aperture therein. The first and second shutter blades are supported to allow parallel linear motion. A motor gear is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position in which the first and second light transmitting apertures are in an overlapping relationship with respect to one another, and a closed position in which the first and second light transmitting apertures are in a non-overlapping relationship with respect to one another.

    Abstract: An apparatus for measuring light in samples using a high intensity light source (12), is presented. The system utilizes bifurcated fiber bundle (26) to transmit light at the excitation and emission wavelength bands. It also uses a band-pass filter (36) for eliminating extraneous light, including that which corresponds to the excitation wavelength range, while permitting the emitted light to pass to a detector (41) for quantitation. The system employs a shutter (39) to shield the detector (41) while the laser light source is activated, and a controller to intermittently activate the laser light and close the shutter. The apparatus preferably includes lenses (16, 17, 37) for better illumination and read out conditions. The apparatus is employed in Luminescence Oxygen Channeling Immunoassays. The method has high sensitivity, accuracy and precision, and the apparatus is highly compact. Accordingly, the analyzer can perform assays in nanoliter to microliter sample volumes in standard microplates having at least 96, 384 or 1536 wells.

    Abstract: A method and apparatus for visually detecting when a luminescent dissolved oxygen sensor is operating is disclosed. In one example embodiment of the invention, a shutter (216) is placed into the light tight container. When the shutter (216) is open, a user can see into the light tight container and verify probe operation. When the shutter (216) is closed, external light is prevented from entering the light tight container and affecting measurement accuracy. In another example embodiment of the invention, one end of a light pipe (526) is placed on the outside of the light tight container, and the other end is positioned to view the light source (504) of the probe. In another example embodiment of the invention a second light source (628), visible on the outside of the light tight container, is used to verify operation of the probe. In another example embodiment of the invention, a predetermined area is left open in the optically opaque hydrostatically transparent (814) on the face of the sensor window, allowing a user to see light from the sensor when the sensor is operating properly.

    Abstract: The present invention relates to an apparatus and method for imaging time resolved fluorescence in biochemical and medical samples. In a primary aspect, the device includes a lens of large aperture, a flash lamp in the illumination path, a fast-acting solid state shutter or a gated detector in the emission path, a device for delivering homogenous monochromatic illumination to a plurality of wells distributed within a microwell plate, a digital camera of high quantum efficiency, and a computer. under computer control, the lamp is pulsed at short intervals. The fast-acting emission shutter or gated detector operates to limit exposure of the camera to a period some microseconds after the extinction of each lamp pulse, during which only delayed fluorescence is transmitted to the camera. The invention achieves simultaneous time resolved imaging of a plurality of samples, with high sensitivity and high throughput.
