Optical coherence tomography

Our Dual axis voice coil mirror (VCM) with position feedback allows for a new generation of compact optical coherence tomography (OCT) systems.

A key advantage is the single rotation point close to the mirror surface. This allows for example to bring the mirror close to the eye and to scan a larger section of the retina.

Fluorescent imaging

Fluorescent imaging is a widely applied tool in research and in the biotech industry. It relies on narrow-band laser excitation of fluorescent markers.

Optotune’s laser speckle reducers help to homogenize and de-speckle the excitation light, which leads to a more reliable detection.

Optotune’s liquid lens technology can be scaled down to fit into the tip of an endoscope and thus allowing for fast auto-focusing.

Please contact us with your challenging requirements. Alternatively, one of our standard tunable lenses can be integrated into the C-mount camera adapter in order to carry out remote-focusing through the relay system.

Intraoral scanners

The dental CAD/CAM market grows rapidly. Dental cameras/intra-oral scanners are at the heart of the paradigm change from traditional to digital workflow.

Optotune’s laser speckle reducers and focus tunable lenses allow for more accurate and faster 3D scanning.

Raman spectroscopy

Raman scattering is a growing market triggered by authentication and counterfeit detection, incoming quality control and airport/homeland security. Raman scattering is an inefficient process and therefore requires high-NA objectives that collect as many photons as possible.

Those objectives result in low depth of field. Placing a tunable lens in the optical path allows to average the Raman signal over different depths and to adjust variations in working distance in case of handheld devices.
