  • DeltaRAM-X Fluorescence Microscope Illuminator
Jul 2013
Optical Building BlocksRequest Info
BIRMINGHAM, N.J., July 8, 2013 — Optical Building Blocks Corp. has introduced the DeltaRAM-X millisecond wavelength-switching fluorescence microscope illuminator for applications in the life sciences.

The device is suited for intracellular ion research of Fura-2 (Ca++), BCECF (pH), SBFI (Na++), Förster resonance energy transfer (FRET) and more. Although it is most commonly used for mammalian cellular research in neurology, cardiology, biophysics and electrophysiology, it can also be used for other spectroscopy applications requiring high-speed wavelength switching.

The self-contained, self-aligned illuminator couples to all fluorescence microscopes via a flexible liquid lightguide and microscope-specific adapter. The device can switch between wavelengths from 250 to 650 nm in only 2 ms, making it suitable for tracking fast intracellular ion changes. It also features a continuously adjustable bandwidth from 0 to 24 nm and a transistor-transistor logic shutter to prevent photobleaching.
