Model TL-0250
Every unit ships with its own acceptance report. Extension tubes and adapters quoted with the lens.
When the part is too large for a standard measurement lens, the TL-0250 covers a wider field of view while keeping the same constant-scale behaviour.
The design keeps parts of varying height in focus without any mechanical adjustment between part types, which simplifies fixtures considerably.
This is a large, heavy lens. The supplied clamp ring carries the weight on the barrel rather than on the camera mount, and keeps the assembly aligned on a moving machine.
