Lunch Chat: High speed large aperture tunable lenses and their applications

Tue, 20.02.2024, online


We are pleased to announce and invite you to one of our weekly online zoom events.

High speed large aperture tunable lenses and their applications

Rigid glass & plastic lenses have the downside that their depth of field is limited. Focus tunable liquid lenses overcome this issue by using membranes that change their curvature in response to an electrical signal. Optotune’s liquid lens portfolio covers clear apertures from 3mm to 33mm.
In this talk different lens architectures are discussed. Key issues of liquid lenses such as thermal drift, gravity coma and lack of suitable AR coatings are addressed, and solutions presented. Applications are shown in the fields of imaging, laser processing, medical, and head-mounted displays for AR/VR.
