The Basler C11-2520-12M-P Premium 12 megapixel lens features an 25 mm focal length and a short 100 mm minimum object distance.

Basler lenses have been designed with a needs-oriented approach to deliver an excellent price/performance ratio. The Basler C11 Premium lenses are intended for use with most 12 megapixel cameras having an image sensor not larger than 17.6 mm diagonal, and a pixel size of 3.57 µm or larger.

The Basler C11 Premium lenses are appropriate for typical machine vision installations. They were designed for relatively short working distances, and have thumbscrews to lock both the aperture and focus.

We include this lens in our catalog because it offers a great value. You will however find that some higher-cost lenses offer a larger aperture, less distortion, greater resistance to vibration, and more consistent performance across a variety of installation conditions.
