The Sofra L135F2.8 135mm F2.8 C-Mount Objective Lens features manual focus and an integrated adjustable iris diaphragm. These lenses also feature broadband lens coatings making them ideal low cost solutions for imaging in the near-infrared spectral range with reduced flare and ghosting. A C-mount Extension Tube kit is also available for those applications requiring close focus and higher magnification.
Also included are two quartz objective lenses that are suitable for imaging from UV through Near-IR range. These objective lenses perform well for monochromatic imaging in the noted spectral range. It is important to note that they are not chromatically corrected for the entire spectral range.
