LED transmitted light base TL5000 Ergo with automatic aperture, 65 mm field - Leica 10450541

Zooming in transmitted light costs contrast and depth of field when the aperture does not follow. The Leica TL5000 Ergo adjusts the aperture automatically to the zoom position of the optics and therefore delivers the best available image across the whole zoom range, at a height of only 42 mm.

Benefits in use

• Automatic aperture that follows the zoom setting, so contrast does not have to be corrected by hand when the magnification changes.
• Maximum numerical aperture of 0.9, so fine structures in the specimen are still resolved at high magnification.
• Field of view of 65 mm diameter, whole objects and larger specimens fit completely into the illuminated area.
• Three contrast methods on one base, brightfield for the overview, Rottermann contrast for flat structures and a low reflection darkfield for edges.
• Very flat design at 42 mm height, which keeps the viewing angle on the specimen ergonomic and the setup low.
• Coded base with full integration into Leica LAS and LAS AF, so settings can be reproduced for recurring inspections.

Applications

Transmitted light inspection of transparent and semi transparent samples, checking of edges, contours and bores, documented inspection routines with repeatable illumination settings, laboratory, materials testing and training.

Compatibility and scope of delivery

The transmitted light base is supplied on its own. Microscope body, focus column, carrier and eyepieces are not included and are matched to the existing system. Full automation including store and recall of settings is used through Leica LAS or LAS AF, and without software the contrast methods remain selectable with the buttons on the base.
