Tamron announces Three New Compact φ29mm Machine-Vision Lenses Compatible with 2/3” Imagers and 8-Mega Pixel Resolution (MA23F series)

May 21, 2020, Saitama, Japan - Tamron Co., Ltd. (President & CEO: Shiro Ajisaka; Headquarters: Saitama City, Japan), a leading manufacturer of optics for diverse applications, announces the market-launch of three new industry-standard1 φ29mm compact-size fixed-focal lenses for machine-vision applications, compatible with 2/3” imagers and 8-mega pixel high resolution: Model MA23F08V / MA23F25V / MA23F35V.

Mega-pixel cameras used for machine-vision applications including production equipment, circuit board mounting equipment, various test equipment, and various engineering machines, are migrating toward higher resolution. Tamron currently offers a whole array of mega-pixel machine-vision lenses of 35 different models compatible with imagers of various sizes.

To support diverse machine-vision applications, Tamron announces three new 8-mega pixel machine-vision lenses, compatible with 2/3” imagers with 1:1 pixel-aspect ratio (square pixel).

For use in machine-vision applications limited in installation space, the new models are compact-designed with an outer diameter φ29mm and are equipped with an improved anti-vibration and anti-shock mechanism.

Tamron continues development of industry-leading high-resolution fixed-focal lenses that address customers’ critical requirements and needs in all machine-vision applications, and pursues optical performance that assures distinguished fidelity in all image details, and excellent user utility.

The new models are compatible with 2/3” imagers, supporting 2.74μm pixel-pitch and max 8-mega pixel resolution, offering resolution and contrast outperforming other φ29mm machine-vision lenses.

Tamron’s state-of-the-art optics technology significantly reduces TV distortion compared with previous models.
Specification: MA23F08V: -0.6% / MA23F25V: -0.01% / MA23F35V: 0.04%

A new comprehensive lens design assures high contrast and resolution at commonly used close-up distances.

Thorough inspection is performed on the imaging resolution from the center to the periphery, warranting high-contrast and high-resolution without unbalanced blurring throughout the entire lens view.

A newly designed mechanism improves on anti-vibration and anti-shock performance compared with previous models, limiting the optical (image) deflection to less than 10μm even for the severe impact of vibrations and shocks of max 10G of magnitude.
*Vibration frequency 10-60Hz (amplitude 0.75mm), vibration frequency 60-200Hz (acceleration 100m/s2), and the number of cycles: 50 cycles.

A lock-screw provided with the models can be replaced with any embedding-type setscrew. This further reduces the overall diameter of the lens barrel for more compact installation.
