C VIS-NIR Series Fixed Focal Length Lenses

TECHSPEC® C VIS-NIR Series Fixed Focal Length Lenses are designed for use in machine vision applications that require NIR or VIS-NIR performance, with the working distance and resolution requirements of factory automation and inspection in mind. Featuring large maximum apertures and a Broadband Anti-Reflection (BBAR) coating designed out to 1000nm, these high performance lenses can be used in even the most restrictive lighting conditions. TECHSPEC® C VIS-NIR Series Fixed Focal Length Lenses are manufactured to a high tolerance, resulting in greater levels of imaging performance and low lens-to-lens variation, assuring simple installing into multiple systems. By combining high optical performance, industrial features, and small package size, the C VIS-NIR Series lenses represent a new standard in factory automation optics.

Also available with a VIS Broadband Anti-Reflection (BBAR) Coating.

Note: For IR imaging alone, UV-VIS Cut Filters are available and thread directly onto the front filter threads of the 4.5mm, 16mm, 25mm, 35mm and 50mm FL lenses.
