EOS Retina Technology
Canon has a long tradition to create digital cameras that are optimized for a specific application. For instance with the EOS Ra, Canon is offering a camera ideally suitable for Astrophotography , using a modified optical low-pass filter that provides increased sensitivity to IR light and captures more colors. Compared with a standard EOS camera, four times more light at 656nm is transmitted through the Canon EOS Ra's low-pass filter. This allows the distinct red tones of H-alpha emission nebulae to be rendered with incredible color and clarity.
Using their expertise, Canon has created a unique digital camera, dedicated for ophthalmic photography, for the best possible image: the EOS Retina.
The current version of the EOS Retina has an impressive resolution of 32 MegaPixel and utillizes the quality of the optical system of the retinal camera to the fullest.
The EOS retina is completely external of the retinal camera and can eventually be exchanged easily in the future for eventual upgrading to a newer digital camera version with even more Mega Pixels.
