Our standard widefield tube lenses for the visible wavelength range can also be used for laser scanning purposes when paired with the CLS-SL visible scan lens for example. These lenses can also be used for widefield imaging over their specified wavelength ranges. These lenses create a telecentric system when paired with our SL50-CLS2, SL50-2P2, and SL50-3P scan lenses, for use in point-by-point galvo scanning of the object plane. Our laser scanning tube lenses are optimized for laser scanning applications, such as confocal laser scanning, two-photon microscopy, and three-photon microscopy. Telecentric Tube Lenses for Laser Scanning and Widefield Imaging Specifications for all lenses can be found on the Specs tab, as well as Zemax black box files for all lenses except the ITL200.
The TTL200 series of tube lenses are specifically designed to offer a wider diffraction-limited axial color range than the ITL200 tube lens. Their effective focal lengths correspond to the design focal lengths of popular objectives (see the Magnification & FOV tab for details). Our widefield tube lenses are AR-coated for high transmission and provide diffraction-limited axial color performance for the UV, visible, and NIR wavelength ranges see the Specs tab for performance data.
Designed for high-resolution imaging, biomedical, machine vision, and laser scanning applications, these lenses can be aligned in pairs to create relays, combined with objectives to create different effective magnification ratios at a scientific camera, used as drop-in replacements for tube lenses in existing systems, or integrated into DIY Cerna ® Microscopes and other home-built microscopy setups to generate high-quality images. These infinity-corrected tube lenses are designed for use with infinity-corrected objectives from all major manufacturers, including the dry, oil immersion, and physiology microscope objectives sold by Thorlabs.
