FUJIFILM Launches FUJINON CF-ZA-1S Series Ultra High Resolution Lenses for Machine Vision Cameras
Ideal for effective product inspection and measurement on production lines requiring high precision and compatible with large sensors with high pixel counts
SYDNEY, 2 November 2018 – FUJIFILM has developed the “FUJINON CF-ZA-1S series” (“CF-ZA-1S”), a series of ultra-high resolution lenses designed for machine vision cameras used for product inspection and measurement on production lines. The lenses are compatible with large camera sensors with a high pixel count of 1.1-inch (2.5µm pixel pitch*** equivalent to 23 megapixels).
In production lines, it is common practice to use machine vision system to confirm images of products so as to conduct automatic product inspection and measurement. In years to come, the demand for machine vision systems is expected to grow due to the increasing automation of production lines and further reductions in the number of human operators. Currently, the demand for high precision inspection and measurement systems is growing not only in the electronic components and automotive components fields but also in the field of larger-sized products such as organic EL displays and LCD displays. As the sensors used for machine vision cameras become increasingly large and incorporate an ever higher pixel count, lenses, which are the first “gateway” for image information, now also require higher levels of performance.
The CF-ZA-1S series, set for launch in February 2019, is a series of ultra-high resolution lenses designed for use with machine vision cameras and compatible with large camera sensors with a high pixel count of 1.1-inch・2.5µm pixel pitch***(equivalent to 23 megapixels).
The lenses incorporate Fujifilm’s proprietary 4D high resolution*4technology, providing superior image clarity. In addition, when the aperture is set to F4, the setting commonly chosen by users, the relative illumination ratio* is maintained at over 90%**, ensuring that the lens produces images that operate in all areas from the centre through to the periphery. This eliminates the need for light intensity compensation, which may cause noise into the image, facilitating efficient high-precision product inspections. Furthermore, the lenses are designed to be compact, with a world-smallest*5 external diameter of just 39mm*6, and the lenses’ high-quality anti-shock and vibration performance, which maintains variations of the optical axis*7 equal to or below 10µm*8 makes the lenses highly suitable for installation in a diverse range of manufacturing environments.
The CF-ZA-1S is suitable not only for the inspection and measurement of electronic components but also for large-sized products such as organic EL displays and LCD displays. The series provides a lineup of six different lens models*9 with different focal lengths, allowing customers to choose the lens most appropriate for their desired application.
In addition to the CF-ZA-1S series, Fujifilm will also, from January 2019, launch the “FUJINON HF-HA-1S series” (“HF-HA-1S”). This series is an update of the “FUJINON HF-HA-1B series”, already in use in a wide range of manufacturing environments, which are compatible with sensors up to a maximum size of 2/3-inch・6.2µm pixel pitch (maximum size equivalent to 1.5 megapixels), and are characterised by compact lens bodies with external diameters of 29.5mm. The update adds additional anti-shock and vibration performance to the existing series.
Fujifilm currently provides a wide range of lenses that fit with the times of high-quality digital imaging including lenses for television and surveillance cameras. These products harness the optical technology acquired by Fujifilm over many years as well as Fujifilm’s precision processing and assembly know-how. With a broad portfolio of 45 different lens models with high performance, high image quality and high lens quality, Fujifilm is committed to meeting customers’ diverse needs in the machine vision field, where sustained demand growth is expected.
• *This refers to the ratio of the light intensity at the periphery of the image as compared to the centre of the image.
• **When the aperture is in the F4 setting, which is commonly chosen by users.
• ***This is an index of the sensitivity of the image sensor. The unit of µm refers to the distance between the respective centres of adjacent pixels. The shorter the distance, the higher the pixel density and the higher the resolution. In the case of a 1.1-inch sensor, a pixel pitch of 2.5µm corresponds to a 23 megapixel camera.
• *4This is the name given to the unique high-resolution achieved by FUJINON lenses through a mechanism for maintaining a constant high resolution from the centre of the image to the periphery (2D) and mitigating resolution degradation as the shooting distance and aperture setting change (2D).
• *5Applies to lenses for use in machine vision camera compatible with 1.1-inch high sensitivity image sensors with a pixel pitch below 3.0µm.
• *6Excludes the FUJINON CF8ZA-1S which has a focal length of 8mm.
• *7This is the displacement of the image that occurs when vibrations and impacts result in the lens glass shifting from its original position. If this displacement of the image causes changes to the area captured by the image, it may result in malfunction of the image sensor.
• *8This movement is measured after fixing the lens to the vibration table, subjecting the lens to vibration experiments defined according to JISC 60068-2-6 (vibration frequency of 10-60 Hz, amplitude of 0.75mm, vibration frequency of 60-500 Hz, acceleration of 100 m/s2, 50 cycles of the “sweep” frequency followed by an impact force of 10 G.
• *9The six focal lengths are 8mm, 12mm, 16mm, 25mm, 35mm, and 50mm.
