Tube Lenses

A Tube Lens is a special lens or lens assembly specifically designed for infinite conjugate microscopes. The primary function of this lens is to be combined with the objective lens to form a complete microscope system and achieve further magnification and transmission of the image.

In the microscope system, the infinite conjugate objective lens emits parallel light from the sample, and this parallel light is then focused by the Tube Lens, forming a clear image. The ratio of the focal length of the Tube Lens to that of the objective lens determines the total magnification of the system. By selecting different focal lengths of the Tube Lens, the magnification of the system can be changed, thus meeting different observation requirements.

Our company produces and manufactures tube lenses suitable for different wavelength bands, which can be applied in various scenarios.

Aberration correction range:

• TL-1, TL-2, TL-3: Visible region (435.8–656.3 nm)
• TL-L: Near-ultraviolet (355 nm) to near-infrared region (1800 nm)
