Ophthalmology
Whether measuring the refractive power of the eye, scanning the retina and the anterior eye segment or taking a fundus image - Optotune’s components are used in a range of ophthalmic instruments.
Main benefits:
Most compact way to correct refraction
Continuous adjustment in real-time
+/- 20 diopters spherical, +/- 8 diopters cylindrical (Stokes approach)
Large clear aperture
There is no more natural way to compensate for visual defects of the human eye than by using focus tunable lenses, which basically work according to the same principles. Currently, most ophthalmic equipment relies on manual selection and alignment of one or several glass lenses to achieve the desired correction. With focus tunable lenses, correction can be done with one single lens, which can be adjusted continuously and precisely in real-time. Spherical lenses can be built with apertures of up to 40mm and optical power ranging from -20 to +20 diopters.
The large optical power tuning range in combination with the excellent dispersion properties allows to build a new generation of fast and compact ophthalmic instruments. Also, our 2D beam-steering mirrors are a great way to guide the diagnostic light beam into different parts of the eye. Maybe our beam-shifting devices will boost your instrument’s resolution.
Optotune has experience with component development for the ophthalmic instruments market and we work with some of the largest companies in the sector.
