MegaVision Imaging Products


The E1-i digital camera/camera back is designed for flexible image capture in relatively low-light applications where it’s 2-megapixels enable rapid readout and high sensitivity.  It provides good dynamic range, live focus, electronic shuttering, and easy integration.  When interfaced with an appropriate host computer and coupled to an optional C-mount or F-mount lens adapter, the E1-i becomes a complete camera system.


  • The E1-i comprises 1.92 megapixels in a 1600X1200 format and provides high sensitivity, low noise, electronic shuttering, and live focus over a FireWire interface.

  • Flexible trigger input and internal logic controllers facilitate interfacing to a wide range of host camera systems.  IEEE 1394 (FireWire) interface eliminates many support issues and eases integration  with host computer systems.

  • A replete SDK, which supports MegaVision’s entire line of digital backs, enables rapid integration with custom image capture applications.  The SDK enables image capture, calibration, and processing.

  • MegaVision’s calibrated color development enables custom renderings to achieve optimum diagnostic quality.

  • Raw files may be saved in industry standard DNG format, and developed images may be saved in either TIFF or JPG.

  • MegaVision can also provide with the E1-i its award winning PhotoShoot capture application as an aid to application development, or as a stand-alone capture, assessment, and management software in its own right.
