Schneider Industrial Optics 21-1103137 TOPAZ 2.8/12mm C ** Standard Lens TOPAZ 1 inch Format Lenses Visible Corrected (Broadband Coated for 400-700nm or 700-1000nm) These lenses are designed for use at long working distances--from ~2m out to infinity. Focusing is achieved by rotating the main lens barrel via fine internal thread with locking collar to secure focus. The lenses have a front thread to accept filters directly. Image Circle: 17.6mm, Filter Size: M62x0.75**, Optimized for different working distances these compact and robust 1.1” / 1.2" C-Mount lenses are the perfect choice for demanding short and long distance applications even in harsh environment. With the special broadband AR coating they can be used in the visible 400 to 700 nm and in the NIR 700 to 1000 nm range. The lenses are also available in a version with a motorized iris.TOPAZ compact lenses are tested to DIN standards to ensure they meet stringent environmental requirements. These tests check the durability of the compact lenses, their resistance to temperature changes and their ability to withstand shock tests and sinusoidal vibration. This ensures that the industrial lenses are up to the task in demanding industrial applications such as machine vision or automated optical inspection, providing consistent performance and reliability over time.
