Mega-Pixel Machine Vision Lens Series
Ultra-High-Performance Machine Vision Fixed-Focal Lenses
1.1″ f=50mm F/1.8 (Model: M111FM50)
TAMRON
Industry-Leading High Contrast and Resolution
The lenses, optimized for 3.1-μm-pixel-pitch images, equivalent to 1.1″ 12 mega-pixels. Use of state-of-the-art optical technology enables high-contrast and high-resolution from the corner to the periphery of images despite the large aperture size. Tamron's machine vision xed-focal lens line-up also opens gates to other area of applications including trafc monitoring, notably for ITS (Intelligent Transport Systems).
Combination of Advanced Coating Technology and Use of Diverse Types of Lenses
Tamron's proprietary coating technology is employed to enhance the lens light transmittance, and combinations of diverse types of lens elements are optimized to bring the resolution to the maximum height. An aspherical lens is deployed on a wide-angle model for the rst time in Tamron�fs machine vision lenses.
Uncompromised Image Quality at Close Distances
High image-delity is maintained at frequently-used close distance.
Enhanced Functionality and Utility
Well-tuned rotation torque of both focus and iris control rings facilities smooth adjustments of focusing and aperture. For ease of installation, the rings are also equipped with a lock mechanism, similar to Tamron's other current machine vision xed-focal lens models; the rings can be locked at a choice of three lock screw positions (two positions for the Model: M111FM08).
Designed for Rugged Lens Appearance
Metal barrels are adopted for durability and vibration-resiliency, giving a rugged appearance to the lenses.
