liquid focus lenses
Our lenses for universal applications
Key features of the Lenses
- Focus tunable liquid lens included
- Large working distance range
- Fast focus within milliseconds
- Large image circle
These lenses are combining an approved Schneider-Kreuznach lens and one of Optotunes Focus Tunable Lenses EL-16-40-TC. 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 or 8 mm so the liquid lens can always be used in its optimal operating range.
Included in delivery is the PYRITE lens with integrated liquid lens element.
Which exact liquid lens element is used?
EL-16-40-TC (5D version) from Optotune Switzerland AG
Where can I find all special and more detailed information regarding the liquid lens element and accessorial components?

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.
|Extension tube||PYRITE LF F4.0/60 mm|
|Working distance range||Magnification|
|None||Infinity to 650 mm||0x to -0.09x|
|5 mm||870 mm to 340 mm||-0.07x to -0.18x|
|8 mm||565 mm to 270 mm||-0.12x to -0.23x|
|Extension tube||PYRITE LF F4.0/80 mm|
|Working distance range||Magnification|
|None||Infinity to 750 mm||0x to -0.1x|
|7 mm||1430 mm to 400 mm||-0.06x to -0.2x|
What components and software are needed to use the lens?
• Controller: lens driver 4i
• Cable to connect controller and liquid focus lens: electrical lens connection cable 6-pin Hirose male to 6-pin Hirose female connector
• Software to drive the focus tunable lens: link
Set up of components?
• Connect the controller to your PC directly or use an USB extension cable.
• Connect the controller to the focus tunable lens with the Hirose cable.
• Download the software to set up and drive your liquid lens.

Machine vision technologies play an important role in the automated sorting of parcels in parcel centers.
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.
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.
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.
By protecting the lens, eliminating unwanted wavelengths and enhancing contrast, optical filters can improve the image quality of your lens in industrial applications.
Maximise the potential of your industrial lens with our range of high quality accessories including camera adapters, extension tubes, filter holders and UNIFOC.
