Telecentric Lens Optics for Micro Machine Vision

MORITEX and SCHOTT present High-Resolution Telecentric Lens offering 20x Magnification

Tokyo (Japan) / Mainz (Germany), March 22, 2010 — MORITEX Corporation has designed a new telecentric lens for machine vision applications. With its optical magnification of 20x and a numerical aperture of 0.35, the “SOD-20X-V1” offers a resolution on par with a microscope lens. Its long working distance of 36.5 mm makes the lens less susceptible to heat, particles or oil which may be emitted during the examination process. Coupling this model with an optional rear converter lens even provides an optical magnification of 30x or 40x. This allows for imaging of fine, detailed characteristics with a precision that has not been reached until now.

In biosciences and laboratory automation or in industries such as electronics, solar and optics the structures of products are becoming finer and finer. In order to inspect them with high precision, machine vision systems increasingly need to be equipped with high-resolution magnification lenses. As a response to the growing demand, MORITEX has developed the Super Optical Device (SOD)-X Series of high power lenses.

“SOD-20X-V1” exceeds the performance of its predecessor model “SOD-10X-V1” (optical magnification of 10x, numerical aperture of 0.23). The telecentric lens has been designed as a multi-functional model with an optical magnification of 20x and a numerical aperture (NA) of 0.35. Coupling it with an optional rear converter lens, such as the SOD-1.5X or SOD-2X, even provides an optical magnification of 30x or 40x.

This high resolution magnification lens has been optimized for machine vision applications and offers a large working distance (WD) of 36.5 mm. Its mountable body has a low profile which allows space to be reserved for oblique lighting. This is supported by an integrated coaxial epi-illumination function. An adjustable diaphragm enables the fine tuning of the depth of field. This allows for a very clear image that is rich in contrast.
