Analyze Samples in the Lab or Field with this New Portable Fluorescence Spectrometer

2010-05 Ring Spec

Custom software and curved reflective surface in this spectrometer reduces size and focuses light so well that inexpensive LEDs replace expensive light sources.

Problems 1.) Important science curricula may not be adequately addressed in high schools because spectroscopy instruments are too expensive to purchase and maintain  2.) Field technicians have to take water and soil samples to a lab for spectroscopy analysis, adding time and complication  3.) Valuable data is not available from remote sensors due to spectrometer power and durability limitations.

Solution: A portable, durable, inexpensive florescence spectrometer

3D Biplane Microscopy

A microscopy system is configured for creating 3D images from individually localized probe molecules. The microscopy system includes a sample stage, an activation light source, a readout light source, a beam splitting device, at least one camera, and a controller. The activation light source activates probes of at least one probe subset of photo-sensitive luminescent probes, and the readout light source causes luminescence light from the activated probes. The beam splitting device splits the luminescence light into at least two paths to create at least two detection planes that correspond to the same or different number of object planes of the sample. The camera detects simultaneously the at least two detection planes, the number of object planes being represented in the camera by the same number of recorded regions of interest. The controller is programmable to combine a signal from the regions of interest into a 3D data.
