The Investigater utilizes frame grabbing technology to integrate multiple images, reducing or eliminating random pixel noise. The Investigater enables the acquisition of “noise free”, low light level images from Dage IR-1000 cameras. The Investigater accomplishes this by gating, grabbing, and then displaying the resulting image to a monitor.
Designed as a stand-alone unit, the Investigater allows timing control and memory storage and display without the need of a frame grabber board or computer. Connects to a computer for image capture via PCI. When coupled with the IR-1000 cameras, the resulting system produces brilliant images from low-light fluorescence to brightfield.

The InvestiGater enables the acquisition of “noise free” low light level images from the IR-1000 camera (Spectral response 380nm to 1100nm). The InvestiGater accomplishes this by “gating” (allowing a number of frames to accumulate charge on the CCD detector), grabbing and displaying the image. As long as the signal is present above background noise, the signal from the sample will build up faster than random noise. Unlike Image averaging, the InvestiGater will “normalize” the image to change the range of pixel intensity values to maximize the contrast (histogram or contrast stretching). This can result in brilliant images from low light/low signal environments.
