Two New RICOH FL Series FA Lenses
Extending the existing lens line-up to be compatible
with one-inch format cameras up to nine megapixels
Ricoh Industrial Solutions Inc. (President and CEO: Katsunori Nakata) will be introducing two
new lenses with focal lengths of 25mm and 35mm to complement the current RICOH FL Series
Lenses (with 50mm and 75mm focal lengths) that are compatible with 1” format cameras with up
to nine megapixel resolution that were released in November 2014. The new lenses, with their
wide angle of view, will demonstrate their excellent performance with a wide range of subjects,
including visual and foreign substance inspections on everything from precision machined items
to containers.
As with the 50mm and 75mm focal length lenses previously introduced, these new lenses
feature a φ42mm compact design, despite their nine megapixel high resolution. Additionally,the
troublesome lens distortions that normally occur during image measurement and recognition
have been significantly reduced to less than 0.1% (TV distortion value) with the technology
employed by the new lenses.
Lenses up to two megapixels are currently dominant in the FA camera market. However, the
market for high resolution nine megapixel class lenses is expected to grow. By tackling this trend
early in the development cycle, RICOH is able to create a line-up of lenses that can respond to
the diverse needs of our customers. In the future, Ricoh Industrial Solutions Inc. will continue
striving to further expand sales in the FA lens market.
<Key Features of the Two New RICOH FL Series FA Lenses>
1. High resolution and high contrast at 9 megapixels
These lenses are compatible with 3.69μm pixel pitch, 1” format industrial cameras with
resolution of up to 9 megapixels. From the center to the periphery, the lenses have a high
resolution of 135 lp/mm. Due to minimal degradation of resolution right up to the
periphery they produce sharp, high contrast images. Therefore, even images on the
periphery are suitable for measurement and inspection.
Their focusing uses a floating mechanism design which reduces aberrations from an
infinite to close working distance.
2. φ42mm compact design
To suit 44 mm housings used for most 9 megapixel cameras, these lenses have a 42 mm
compact design ideal for installation with high performance equipment.
3. Low distortion
Troublesome lens distortions for image measurement and recognition have been
reduced. TV distortion is reduced to less than 0.1%, with very little image distortion,
making the lenses ideal for image measurement.
