Our thulite lenses

The high-resolution THULITE lenses are ideal for image processing applications that require the highest precision and quality. Their compact and robust design makes them reliable even in demanding environments. The optical design of the lenses prevents shadowing on main-beam sensitive sensors and the special broadband AR coating enables use in the visible range from 400 to 700 nm as well as in the NIR range from 700 to 1000 nm. 

THULITE lenses are designed for sensors up to 32 mm diagonal, covering a wide range of applications. They deliver crisp images and precise results with resolutions down to 2.4µm. THULITE lenses offer flexible working distance adjustment, which is advantageous in different situations. Focal lengths of 35mm, 50mm and 75mm are available to meet your specific requirements. Compatibility with M42 and TFL mounts allows easy integration into existing systems. With a maximum aperture of F2.8, THULITE lenses offer excellent performance even in low light conditions.

Mounts for the THULITE lenses


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.


The M42 mount is a widely used thread connection. It has a thread with a diameter of 42 mm and a pitch of 0.75 mm or 1 mm.

The M42 mount is often used for industrial lenses because it provides a simple and robust connection between the camera and the lens. It allows the use of different lenses on one camera and offers a high degree of flexibility in selecting the appropriate lens for the application.
