LBTEK offers tube lenses that are coated with anti-reflection coatings, providing high transmission rates across the ultraviolet, visible, and near-infrared wavelength ranges. These lenses are available in focal lengths of 200 mm and 400 mm and are compatible with infinity-corrected objectives from various leading objective manufacturers. They can be widely used in high-resolution imaging, biomedical applications, machine vision, laser scanning, and more. In system applications, dual tube lenses can be used to build relay imaging systems, combined with objectives to create various magnification imaging systems, serve as replacements for existing system tube lenses, or be used with microscopes to produce high-quality images.
The tube lenses offered by LBTEK are compatible with infinity-corrected objectives from leading manufacturers. The aberration correction ranges are available in three options: visible range (435.8 nm - 656.3 nm), ultraviolet to near-infrared range (355 nm - 1064 nm), and ultraviolet to visible range (266 nm - 620 nm). These lenses maintain high transmission rates within their aberration correction ranges.
