Model TL-0512
Every unit ships with its own acceptance report. Extension tubes and adapters quoted with the lens.
The TL-0512 is our most popular measurement lens, designed for bench inspection cells that check the size and shape of machined, stamped and moulded parts.
With an ordinary lens, a part that sits slightly closer to the camera looks slightly larger, which ruins a precise measurement. This design keeps the image scale constant even when the part position varies — which is the whole reason this type of lens exists.
For outline measurement, pair it with a backlight. For surface features, a low-angle ring light keeps the image even without harsh reflections. Both configurations are quoted with the lens.
