The A-39N liquid lens is specifically designed for adjustable focal length products that require a large through-aperture, including those using telephoto objectives, large sensors, C-interface objectives, and laser beamforming. This makes the A-39N liquid lens ideal for use in industrial vision, medical imaging cameras, optical instruments, and biometric systems.

The A-39N uses Varioptic's breakthrough liquid lens technology to achieve an adjustable focal length without any moving parts.

Features of the A-39N include a dynamic range of 20 diopters, ensuring a 5 cm focus capability. It also has the same low energy consumption, high impact resistance and fast focusing capability of the A-Series liquid lenses.
