Our ONYX lenses

ONYX lenses are an excellent solution for environments where both low light and high speed are critical. With an ultra-high F0.95 aperture, these fast lenses offer the ability to capture exceptionally clear and detailed images even in low light with sensors up to 1".

ONYX lenses are specifically designed for applications where low light is available and fast motion needs to be captured. The robust mechanical design of the lenses ensures reliable performance even under adverse conditions. In addition, the ability to lock the focus and iris with locking screws increases stability in use (the iris screw is omitted in the fixed iris version).

Applications & Markets of the ONYX lenses

The applications for the fast ONYX lenses are numerous. In bioluminescence, these lenses enable high-precision observations in controlled laboratory environments where minimal light intensity is required. In high-speed imaging, the lenses capture moving objects with remarkable clarity, enabling detailed analysis. Finally, ONYX fast lenses maximize light capture in low-light environments, providing clear and detailed images even in low light conditions.



The lens is suitable for bioluminescence applications under laboratory conditions.

High speed imaging

High-speed imaging

Used in high-speed imaging to capture fast-moving objects with high resolution and clarity for detailed analysis. 

Low light

Low light applications

In low-light applications, the lens collect and focus the maximum amount of light for sensitive imaging.

Mounts for the ONYX lenses


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.

Fixed iris Lenses

ONYX F0.95 25mm C-Mount Fixed Iris

Fixed aperture lenses are particularly robust because they have a fixed aperture, making them a preferred choice for industrial applications. This design eliminates the need for moving aperture parts and increases lens life in harsh environments.
