Frequently asked questions
Answers to the most common questions about our products and services
It measures the two external surfaces, including opaque materials. Two heads acquire opposite-side distances, and thickness is calculated using their reference separation.
On moving or vibrating material, a time offset between channels can create a difference unrelated to thickness. Select a documented synchronous dual-channel controller or acquisition path.
No. It depends on both working ranges and their reference separation. Each surface must remain within its corresponding head range throughout material movement.
Two heads, compatible fibers, synchronous control/acquisition, a stable mounting structure, and power/data connections. Establishing reference separation is part of setup.
External-surface measurement uses two distances and a reference separation. Refractive-index correction concerns one-sided measurement through transparent material; these are different methods.
