May 9, 2022, Commack, NY - Tamron announces the launch of three new models of an industry-standard* Ø29mm compact-size fixed-focal lenses for machine vision, compatible with 2/3" imagers and 8-megapixel high resolution—Model MA23F12V (12mm), MA23F16V (16mm), and MA23F50V (50mm) on May 10, 2022. These three new lenses expand the currently available MA23F series— Model MA23F08V (8mm), MA23F25V (25mm), and MA23F35V (35mm)— to now offer a total of six different focal lengths ideal for a wide range of applications.

Megapixel cameras used in machine-vision applications including production equipment, substrate mounting equipment, various test equipment, and various engineering machines, are migrating toward higher resolution. Due to the accelerating speed of integration and miniaturization of semiconductor and electrical components, higher definition and resolution are required for the inspection of these devices.

To meet these demands, Tamron expands the currently available portfolio of 2/3" 8-megapixel machine-vision lenses (MA23F Series) by introducing three new models: Model MA23F12V (12mm), MA23F16V (16mm), and MA23F50V (50mm). The new MA23F Series now offers six different focal lengths: 8mm F/2.4, 12mm F/2.4, 16mm F/2.4, 25mm F/2.4, 35mm F/2.4, and 50mm F/2.8 for a wide range of applications.

Compactly designed with an outer diameter Ø29mm, the new MA23F Series lenses are an optimum choice for machine-vision installations that are limited in space and in need of improved anti-vibration and anti-shock protection.

Tamron continues to develop 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 image details, and excellent user utility.

PRODUCT HIGHLIGHTS

1. Unrivaled High Resolution and Contrast in the Industry
The new models are compatible with 2/3" imagers, supporting 2.74μm pixel-pitch and max 8-megapixel resolution, offering resolution and contrast outperforming other Ø29mm machine-vision lenses.

2. Industry-leading Low Distortion (TV Distortion)
Tamron’s state-of-the-art optics technology significantly reduces TV distortion compared with the previous models. Specification: MA23F12V: 0.4% / MA23F16V: -0.05% / MA23F50V: 0.05%

3. High-Quality Performance at Close-up Distances
A new comprehensive lens design assures high contrast and resolution at commonly used close-up distances.

4. Rigorous Inspection of Image Quality
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.

5. New Robust Mechanism for Anti-Vibration and Anti-Shock
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 under severe impact of vibrations and shocks of max 10G of magnitude.
*(Compliant with IEC 60068-2-6 / JIS C 60068-2-6)
Vibration frequency 10-60Hz (amplitude 0.75mm), vibration frequency 60-500Hz (acceleration 100m/S2).

6. A Common-use Setscrew is Attached as a Standard Accessory
A lock-screw that comes with the models can be replaced with an embedding-type setscrew. This further reduces the overall diameter of the lens barrel for further compact installation.
