FL-CC3524-5MX: New RICOH FL Series FA Lens with 35mm focal length
Stronger line-up with the addition of another S-Rank (Best Performance Class) High Performance Lens for 5 Megapixel Cameras
As well as the previous 12,16 and 25mm lenses, which have been receiving good reviews, the new 35mm model uses JIIA (Japan Industrial Imaging Association) lens standards, that satisfy S Rank* (Best Performance Class) criteria, allowing the lenses to take high resolution, high contrast, sharp images over the entire sensor at all working distances.
This lens is developed for 2/3” 5 megapixel cameras, demand for which has dramatically increased in recent years. By providing a φ33mm compact design while still maintaining high resolution, there are now more options available for embedded designs. The introduction of a floating mechanism provides high resolution, high contrast performance over a wide range of imaging distances, from 0.1m to infinity. No matter the imaging distance, this lens will maintain a sharp picture with high performance over the entire area of the screen, meeting machine vision market needs for stable, high inspection/detection precision.
This highly versatile lens can be implemented in a wide variety of fields, from automotive & automotive parts to containers/packaging, security, infrastructure monitoring, and IoT applications.
The lens provides a high resolution image right up to the periphery and has low distortion, making it ideal various applications. Visually inspecting high density printed circuit boards, confirming hairline cracks and other surface defects on sheet metals, checking for missing pixels on LCD monitors, inspecting multiple aspects simultaneously such as the shape, colour and surface of food and pharmaceuticals for imperfections and in making detailed inspections of a wide range of objects. Furthermore, this new high-resolution lens can also be used as a visual sensor in any machine’s vision system.
Lenses up to 2 megapixels are currently dominant in the FA camera market. However, the market is transitioning to higher resolution lenses. By extending our line-up of high-performance 5 megapixel lenses, we are now able to respond further to the diverse market requirements. Our goal is to continue developing new products and further expand our business in the FA lens market. Ricoh’s area scan lenses currently range from VGA to 12 megapixel resolution, supporting sensors from 1/3” to 1.1”.

Evaluation Criteria (S-Rank): Resolving spatial frequency corresponding to the Nyquist frequency over the entire image.
Key Features of the New RICOH FL-CC3524-5MX
- Provides high resolution and high contrast images
Right from the center to the periphery, these lenses have a high resolution of over 147 lp/mm. Due to a minimal degradation of resolution right up to the periphery they produce sharp, high contrast images. Therefore, even images on the periphery can be suitable for measurement and inspection. These lenses use JIIA (Japan Industrial Imaging Association) high performance class/evaluation standards for high definition camera lenses, and satisfy S-Rank (Best Performance Class) criteria. As entire field 5 Megapixel camera lenses, they capture high resolution, low distortion images not just from the center to the periphery but over the entire image measurement field. - Achieves low distortion
Optically designed to reduce distortion, which poses a problem in image measuring and recognition, these lenses keep TV distortion to less than 0.1% (Figure 1), making them ideal for capturing low distortion images over the entire image measurement field.
Figure 1: Distortion - Floating focusing mechanism
The use of a floating mechanism in their focusing systems allows them to capture low-distortion, high resolution images at all distances, from infinity right down to their minimum object distance, demonstrating maximum performance at any magnification (Figure 2).
