Figure 1. LED-CCD multi-wavelength detector.

Figure 1

(A) A schematic configuration of the multi-wavelength LED detector. (B) A digital camera image of the actual detector platform. The detector system components highlighted in the schematic (A) are [1] an SXVF-M7 CCD camera mounted in a homemade acrylic shelf box [2], which was designed to hold the filters and the sample chips. The camera is equipped with a Tamron manual zoom CCTV 4-12 mm, f1.2 C-mount lens [3] with a green band pass emission filter [4] mounted on the end of the lens. The black acrylic 30-well sample chip [5] (also panel E) is placed on a shelf in the camera box above the blue band pass excitation filter [6]. The camera shelf box is placed on the top of the multi-wavelength LED illuminator [7] (also panel C) with light switches to operate the red, blue, green and white LEDs [8]. (C) Digital photograph of the multi-wavelength LED illuminator prior to attachment of the shelf box. (D) Spectra of the white (W), blue (B), green (G) and red (R) LEDs that comprise the multi-wavelength LED illuminator. (E) The black acrylic 30-well chips designed to hold aqueous samples for imaging.
