2/3 inch 12mm F/1.8 6-Megapixel Machine Vision Fixed Focal Length Lens

The Tamron M23FM12 is a 2/3" 12mm F/1.8 6-Megapixel Machine Vision Fixed Focal Length Lens.

Tamron USA, Inc., a leading manufacturer of precision optics for industry and fine photography, is pleased to announce the development of three new 6-Mega-Pixel Machine Vision Fixed Focal Length Lenses. Leveraging leadership and experience in the design and manufacturing of precision, high resolution industrial optics, Tamron is excited to expand its assortment of lenses in this category to meet the growing needs of higher resolution machine vision applications.

Tamron has been long recognized as an innovative source for mega-pixel fixed-focal length lenses for precision industrial applications such as PCB production, inspection machines and engineering devices, affording them valuable insight into industry needs and trends. Trending higher in recent years and growing rapidly is the demand for substantially higher-resolution cameras, requiring exacting, task-specific optics.

As part of an ongoing initiative to address this need, Tamron has developed three additional lenses specifically for use with 2/3” 6-mega-pixel cameras. Joining four already announced 6-mega-pixel fixed-focal length lenses, Tamron’s dedication to meeting customer requirements will be further realized.
