Our Pyrite - LIQUID FOCUS lensES


These lenses are combining an approved Schneider-Kreuznach lens and one of Optotunes Focus Tunable Lenses EL-16-40-TC-5D. They come in two versions for C-Mount and TFL-Mount. To achieve a wide range of working distance the lenses can be combined with extension tubes of 5 mm, 7 mm, 8 mm or 10 mm so the liquid lens can always be used in its optimal operating range.

Working principle with extension tubes
In delivery condition the lens has its optimal working distance starting from infinity. To reach closer distances it is necessary to use an extension tube between lens and camera, so that the liquid lens element can always be used in its comfort zone for focussing. The ranges recommended in the table can additionally be extended in both directions by applying a higher operating current as the imaging power decreases.

Mounts for PYRITE LF lenses

C-Mount

A C-mount is a specific mechanical connection widely used in the industry for cameras and lenses. It is defined by a diameter of 1 inch (25.4 mm) and 32 threads per inch (C-mount thread). This mount allows lenses to be easily and securely attached to cameras and is widely used in machine vision and other applications.


C-mount connectors provide a robust and proven solution for connecting lenses to cameras. The standardization of C-mount also makes it easy to change lenses to meet the changing needs of different applications.

TFL-Mount

A TFL-Mount is a specific mechanical mount used in the industry for cameras and lenses. The term "TFL" stands for "Treaded Filter Lens" and describes the thread system used with this mount. TFL-Mounts are also known as "M30.5x0.5" because they have a thread with a diameter of 30.5 mm and a pitch of 0.5 mm.

The technical characteristics of the TFL-Mount are based on this standardized thread and diameter, which allows high compatibility between different lenses and cameras. This mount is widely used in industrial vision systems and other applications where precision and consistency are important.



Environmental Facts of the PYRITE LF lenses


Our PYRITE liquid focus lenses are tested to DIN standards to ensure they meet stringent environmental requirements. These tests check the durability of the liquid focus lenses, their resistance to temperature changes and their ability to withstand shock tests and sinusoidal vibration. This ensures that the industrial lenses are up to the task in demanding industrial applications such as barcode reading or parcel sorting, providing consistent performance and reliability over time.
