Token slots and threads

Slots and wires in the form of Ø 40 mm tokens cleverly arranged and adapted for calibration curve tracing. The complementarity of the slots and wires will also allow you to verify Babinet's theorem. This accessory is very easy to use when mounted on a component holder (such as lenses). The manufacturing process allows for a precision better than 1 µm. It provides extremely high-quality figures. These tokens are resistant to heat and aging, and are very insensitive to dirt.

- 7 slots and 7 calibrated wires - Slot widths: 30, 40, 60, 80, 100, 150, 200 µm - Spacing: 5 mm
