Canon has a long tradition in designing digital cameras that are optimized for a specific application. For instance, with the EOS Ra, Canon is offering a camera ideally suitable for Astrophotography, which uses a modified optical low-pass filter that provides increased sensitivity to IR light while capturing more colours. 

Compared with the standard EOS camera, Canon EOS Ra's low-pass filter transmits four times more light at 656nm. This allows the distinct red tones of H-alpha emission nebulae to be rendered with incredible colour and clarity.

Using their expertise, Canon has created a unique digital camera dedicated for ophthalmic photography to obtain the best possible image – the EOS Retina.

The internal Canon DIGIC image processor has optimal image parameters for retinal imaging while providing true colour representation.

The dedicated algorithms enable image processing that reduces the gradation of overexposure. This means that low-intensity sections (macula) are clearly visible, while maintaining the gradation in tone of the high-intensity area of the optic disc.

The clinical results are an improvement of the contrast of the nerve fiber layer and the recognition of vascular aneurysms.

All functionalities of the retinal camera have been fully integrated with the EOS retina. 

The EOS Retina is also the heart of the unique Photometric Auto Exposure, which can automatically adjust in real-time the intensity of the observation light and flash.
