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. Due to the accelerating progress of integration and miniaturization of semiconductor and electrical components, increasingly higher definition and resolution are required for the inspection of these devices. Higher resolution is also required outside the areas of machine-vision applications, for example, in social infrastructure, traffic monitoring and surveillance, and railroad system monitoring and inspection.

High Resolution and Contrast Unrivaled in the Industry

The new models are compatible with 1.1” imagers, supporting 2.5μm pixel-pitch and 24-mega (max) pixel resolution, offering resolution and contrast outperforming other 24-mega pixel lenses.

Industry-leading Low Distortion (TV Distortion)

Tamron’s state-of-the-art optics technology significantly reduces TV distortion compared with previous models.
Specification: MA111F25VIR: -0.3%

High-Quality Performance at Close-up Distances

A new comprehensive lens design covering both close-up and infinity shooting distances assures high contrast and resolution throughout the whole focal length range.

Rigorous Inspection of Image Quality

A newly designed mechanism improves 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 10-150Hz (acceleration 50m/s2), and the number of cycles: 20 cycles.

New Robust Mechanism for Anti-Vibration and Anti-Shock

Focus-shift associated with the wide spectrum of 400nm to 850nm is reduced to an absolute minimum, which makes the new lenses an optimum choice for cameras compatible with the visible-light and the NIR band.

A Common-use Setscrew is Attached as a Standard Accessory

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.
