of adaptive optics components
Imagine Eyes’ adaptive optics (AO) components deliver unparalleled performance for measuring ocular wavefront errors, simulating ophthalmic lenses, and enhancing optical resolution of retinal imaging systems.
They enable an AO technology which performs flawlessly when applied to living eyes, and can readily be incorporated in various system configurations.
The AOkit™ is a complete set of AO components specially designed for industrials and researchers who develop ophthalmic instrumentation. It includes:
Each component of the AOkit ideally complements each other, and all of them are seamlessly integrated in a broad variety of systems.

The mirao 52-e uses a patented electromagnetic actuation technology to deform a highly-reflecting membrane. It enables compensating for the wide variety of wavefront errors that affect living eyes with high accuracy. Even eyes suffering from high astigmatism are fully corrected by the mirao 52-e.
It is seamlessly integrated thanks to plug-and-play USB connectivity, small footprint, and compliance with electrical safety and electromagnetic compatibility standards (IEC 61010-1, IEC 61326-1 and IEC 60601-1-2).
It can be operated without the need for developing software when used in combination with the HASO4 first wavefront sensor and WaveTune software. Additionally, for software developers, a complete application programming interface (API) is included with the mirao 52-e product.
Based on patented Shack-Hartmann technology, the HASO4 first includes a 1280 high-quality micro-lens array in a 3.6 x 4.5 mm² pupil. It provides outstanding performance by combining high precision (λ/100) and large measuring range (defocus up to 66 D), which together enable to accurately assess the wide variety of wavefront aberrations that affect living eyes.
Its ergonomic design and the USB 3.0 connectivity allow an easy plug and play installation. Delivered with WaveView wavefront metrology software, it takes only a few clicks to perform wavefront measurement, wavefront reconstruction, or to visualize the spot image and raw camera data.
In ophthalmic adaptive optics systems, the HASO4 first ideally complements the mirao 52-e deformable mirror and WaveTune software.
WaveTune, the successor of Casao™, is a unique application that combines wavefront measurement and correction features with extensive instrument calibration and diagnostics functions. It provides an ergonomic, all-in-one adaptive optics PC workspace.
Included in Imagine Eyes’ AOkit, WaveTune is perfectly adapted to the mirao 52-e deformable mirror and the HASO4 first wavefront sensor. In many cases, it is the only software tool that you need to drive your AO system in both closed and open loop.
Whether you’re an established expert in adaptive optics or just getting started, you’ll be up and running quickly thanks to WaveTune’s user-friendly, feature rich environment.
Imagine Eyes’ products are the most integrated AO components in ophthalmic instruments, including the rtx1, the first adaptive optics retinal camera on the market.
These components have also been successfully implemented in multiple wavefront aberrometers and vision simulators, as well as in a number of retinal imaging instruments in combination with various imaging modalities such as scanning laser ophthalmoscopes (SLO) and optical coherence tomography (OCT).

In all patients, AO images showed dark elements that were smaller than what could be resolved by fundus imaging and OCT
The rtx1 demonstrates that, unlike the common belief, performing AO retinal imaging can be as easy as standard retinal imaging
We, for the first time, visualized longitudinal changes during the recovery of cone photoreceptors in the eyes of VKH patients
The image resolution achieved by this technology is superior to that of any other current diagnostic tool.
Adaptive optics retinal imaging provided non-invasive and sensitive information on the pathologic disruption of the cone mosaic, even in the absence of subjective (visual loss) or objective (diagnostic imaging) abnormalities.
