With the Fujinon TF-MA lens series, FUJIFILM now offers three new machine vision lenses for high-resolution three-chip colour cameras.
The new FUJINON TF-MA lens series from Fujifilm was developed for industrial-use high-resolution three-chip colour cameras and is optimised for precise measurement and inspection tasks.
The special design of the series of three C-mount lenses with focal lengths of 6mm, 14mm, and 25mm meets the highest demands in terms of colour reproduction and optical resolution.
In the machine vision sector, three-chip colour cameras are used in environments where images of highest colour fidelity and optimum image resolution are required.
They incorporate a prism block as beam splitter and utilise band-pass filters that distribute the incident white light to three beam paths for red, green, and blue.
For each colour channel, a separate CMOS or CCD sensor is installed to facilitate the image capture. The complex camera construction requires an assembly accuracy in the subpixel range. As such, the lenses used in high-resolution three-chip colour cameras must provide excellent imaging properties.
Due to the camera-internal prism construction, they also require a compact and precisely adapted design.
The design of Fujifilm’s FUJINON TF-MA series lenses has been optimised to deliver high image quality with consistent sharpness from the center to the corners as well as a low level of distortion.
Their design allows short working distances of 100mm for the 6mm and 14mm lenses and 200mm for the 25mm lens. With dimensions of 48 mm x 62 mm for the 6mm lens and 34mm x 63mm for the 14mm and the 25mm lenses, they are also very compact.
All three lenses in the series deliver optimal image quality on 1/1.8″ sensors with
2.0 µm pixel pitch. Furthermore, they can also be used on sensors of up to 2/3″ with 3.45 µm pixels.
