OMX Blaze

The DeltaVision OMX offers super-resolution imaging using 3D structured illumination (3D-SIM) and/or localization microscopy techniques. The Blaze SIM Module generates an illumination pattern in three dimensions giving a twofold resolution improvement in the X, Y and Z. This translates into an eight fold increase for a 3D volume. The Blaze design consists of an opto-mechanical light pattern generator incorporating high speed galvanometers for manipulating the light beams necessary to generate the 3D-SIM pattern. This is essential as simple line gratings cannot generate the necessary pattern to allow full three dimensional super resolution reconstruction or fully optimize for each excitation wavelength.

Three-Dimensional Structured Illumination (3D-SIM)

3D-SIM is a super-resolution technique that uses structured illumination patterns to achieve sub-diffraction limit imaging. The structured light pattern creates interference moiré patterns with the fine structures of the sample which are captured in the resulting fluorescence images. The sample is imaged using several different orientations and phases of the light pattern then computer algorithms process the data set and generate the final super-resolution image.

Emission filters:

  • DAPI or equivalent dye   435/31 nm
  • CFP or equivalent dye  477/35 nm
  • GFP,AlexaFluor®488 or equivalent 528/48       
  • YFP or equivalent dye  541/22 nm
  • mCherry, AlexaFluor® 568 or equivalent dye  609/37 nm
  • Cy5/AlexaFluor® 647 or equivalent dye 683/40 nm

Resolution:

  • 100-160 nm lateral (depending on wavelength and optics)
  • 300-400 nm axial (depending on wavelengths and optics)
  • It is capable of imaging events in live cells at super resolution. 
    • Capable of 3D imaging at 1 micron slice (120 images) in <1 sec (depending on exposure time)
    • Capable of 2D-SIM imaging at 20 reconstructed frames per second
    • Exclusive high speed galvanometer controller laser shutters with ~200 ?sec  response time

Lasers:

405 nm, 488 nm, 568 nm and 642 nm

Multi- Camera Acquisition:

Can acquisition up to 4 cameras without switching any optical elements, filters or prisms. Multiple cameras operating simultaneously enable imaging of multiple fluorescent probes with no time delays which is critical for applications such as high speed widefield live cell imaging or FRET imaging.

  • Configured with four custom liquid cooled sCMOS cameras
  • Simultaneous multichannel or sequential acquisition modes user selectable through software
  • Custom designed optical path with high scatter light suppression systems for low background imaging noise
  • Each camera channel correctable for axial chromatic shift, focus, rotation and magnification to ensure all detectors are optimally aligned for sample

High Speed Widefield Imaging:

In addition to its super-resolution capability, the DeltaVision OMX system is capable of high speed widefield imaging a solid state illumination system.

  • Imaging speeds over 400 frames per second, simultaneously on 4 channels
  • Exclusive 6 color solid state illumination system capable of running 4 simultaneous excitation wavelengths. Nominal excitation wavelengths 405nm, 445nm, 488nm, 514nm, 568nm, 642nm

Entire System Environmental Enclosure:

The entire DeltaVision OMX microscope is enclosed in a special cabinet that helps control temperature fluctuations, room airflow vibrations and acoustic noise that are critical when imaging at the sub-micron level. This also allows the system to be operated in any room environment eliminating the need to darkrooms or special facilities.

  • Class 1 Laser safe device with laser safety interlock shutters and warning indicators
  • Entire system enclosure enables operation in a normal laboratory environment, no darkroom needed
  • HEPA air filtration with internal positive pressure environment to minimize dust contamination of optical surfaces

Hardware Autofocus:

The laser based hardware autofocus enables our exclusive focus finding feature that can quickly bring a sample to focus then lock on to track the focal position long term.

  • Laser based hardware autofocus
  • Exclusive FocusAssist system for rapid acquisition of focal plane
  • Seamless integration into specimen location and scanning workflow with Spiral Mosaic automated “pan and scan” function
