The LLK5 is a new type of optical sound recorder which enables substantial improvements in quality of optical sound recording by applying „state of the art“ laser technology.

It simplifies the production of the sound negative significantly since no mechanical moving parts are employed in the optical recording path, and offers exceptional proven operational reliability.

The exposure of the analogue mono or stereo sound track is carried out by a focused and scanned beam of a HeNe laser, emitting green light at a wavelength of 543 nm. The laser beam is deflected perpendicular to the film transport direction in relationship to the audio signal by acousticoptical modulators and deflectors. The beam records equidistant light application tracks with a width of 5-7 μm, the envelope of which corresponds to the contours of the analogue optical sound track.

The constant distance of the scan tracks on the film is ensured by triggering the beam movement through a rotary encoder on the sprocket sound drum. This technique also facilitates the excellent wow and flutter characteristics of the LLK5 because the recording is independent from the film speed due to the digital buffer storage of the sound within defined limits.
