TTL-200MP is a high-performance tube lens specifically designed for infinity-corrected microscopy systems, manufactured by LENSTEK. Featuring an effective focal length of 200 mm and a wavelength range of 400 - 2000 nm, it employs an apochromatic optical design to deliver diffraction-limited imaging performance across the entire field of view, providing excellent resolution and color fidelity.

This tube lens is optimized for both laser scanning and widefield imaging applications. In an infinity-corrected optical system, the objective outputs parallel light, which is then focused by the tube lens to form an intermediate image. The TTL-200MP features a telecentric design that ensures the chief ray remains perpendicular to the image plane across the entire field, effectively suppressing edge vignetting and distortion. It offers a diffraction-limited field size of Ø22 mm with an entrance pupil diameter of Ø20 mm, meeting the imaging requirements of large-format cameras and high-precision scanning systems.The TTL-200MP provides excellent system compatibility with standard threaded interfaces, supporting infinity-corrected objective systems from major brands including Thorlabs, Nikon, Olympus, Zeiss, Leica, and Mitutoyo. Its anti-reflective coating covers a broad spectrum from UV to near-infrared, ensuring high transmittance and low wavefront error across a wide wavelength range. Additionally, this tube lens can be combined with scan lenses to construct telecentric imaging systems, making it ideal for confocal microscopy, light sheet microscopy, and laser scanning microscopy applications.

The TTL-200MP is a core component for advanced microscopy imaging and laser scanning systems, widely used in life science research, materials inspection, semiconductor wafer inspection, and precision metrology applications.
