Lenses (for Machine Vision)

CA-L series

High-resolution, Telecentric Macro Lens

CA-LMH Series

Long WD and high resolution

A type with a WD of 110 mm 4.33", which makes it easy to install inside devices, has been added to the lineup. This lens has both support for 2/3" images and a compact and lightweight design. Models with support for coaxial lighting are also available in all types.

Installation in narrow spaces made possible by the right-angle mirror

The right-angle mirror (OP-87895) makes it possible to bend the optical axis by 90 degrees. This enables installations in narrow spaces. The right-angle mirror can also be used with lenses other than the CA-LMH Series.*

* Check in advance whether problems such as vignetting occur.

Distortion free

All models have a TV distortion of 0.01% or lower. These lenses enable a wide range of highly precise measurements from dimension measurement to alignment.

*1 Depending on factors such as the installation orientation and the vibrations of the environment, consider reinforcing the installation such as by implementing countermeasures to hold the lens in place. For information on the locations to hold the lens in place, see the installation examples.
The above values were calculated according to optical design values. Actual values for individual lenses will differ according to precision of assembly.
*2 WD indicates the distance from the tip of the lens to the workpiece.
*3 The depth of field is a theoretical value calculated with a circle of least confusion of 40 µm 1.57 Mil.
*4 The smallest resolvable feature able to be detected under 550 nm wavelength light.
