Image-recognition systems are becoming indispensable in semiconductor manufacturing as processing becomes increasingly precise.
Kyocera has developed exclusive lenses for "machine-vision" applications to meet the latest high-precision requirements.
Fixed Magnification Lenses /
Variable Focusing Lenses
Fixed Magnification Lenses / Variable Focusing Lenses
Applicable to various machine-vision systems for mounting equipment for precision components and inspection equipment for precision substrates and liquid crystal displays (LCDs), which help factory automation and quality control (QC) standardization.
Variable focusing lenses are available as well.
High Resolution Lenses
While objects are continuing to become miniaturized, the need for high-resolution is increasing according to the development of image processing technology. We offer custom lens solutions to meet our customers’ requirements.

Specifications Magnification 0.18x Effective F-no. 6.0 Image-object distance 247.0mm Working distance 130mm TV distortion 0.1% or less Monitor resolution power 2000 TV lines Depth of field ±0.95mm Image size (max) 2/3 inches Mount type C-mount Dimension φ74x99.36mm
-
Specifications Magnification 0.2x to 0.6x Effective F-no. 7.4 to 10.2 Image-object distance 176.1 to 105.1mm Working distance 132.0 to 51.3mm TV distortion 0.1% or less Monitor resolution power 1000 TV lines or over Depth of field ±7mm(0.2x) to
±1mm(0.6x)Image size (max) 1/2 inches Mount type C-mount Dimension φ36x26.6(0.2x) to
36.3mm(0.6x)
Zoom / Motorized Zoom Lenses
-
Customers can select any magnification arbitrarily without exchanging the lens. In particular, the motorized zoom lens offers high durability and high accuracy in the zooming position thanks to the biaxial direct acting drive system with precise ball screw and stepping motor, which is different from conventional cam system. The illumination unit (coaxial/oblique illumination), drive controller and software for variable magnification are supplied optionally.
Telecentric Lenses
-
Telecentric Optical Systems offer minimal fluctuation in magnification over changes in working distance, which allows for effective and even coaxial illumination. It is very well suited for precise measurement or monitoring and is employed in many of our optical systems.
