Thin‑Film & Coating Measurement

Performing laboratory‑grade tasks on‑line with extreme accuracy, our high‑speed NIR Thin-Film spectrometer delivers precise, real‑time monitoring for thin films and coatings. Ideal for production lines, it measures single‑layer and multi‑layer coating thickness, analyze chemical composition, and track residual solvents and other critical parameters.

A Better Way to Ensure Thin‑Film & Coating Uniformity

The Luminar 4020 Thin‑Film spectrometer mounts on an automatic rail system to provide real‑time thin‑film and coating‑thickness measurements across the web. This setup delivers fast, repeatable data directly on the production line, optimizing process control to ensure uniformity in thin films and coatings.

Designed for tough industrial environments, the NIR spectrometer is unaffected by ambient light and resistant to vibration, dust, and dirt. Its advanced optical design ensures stable, cost‑effective operation while while minimizing waste and maintaining consistent coating quality.

Proven Benefits That Drive Performance

Implementing Brimrose AOTF‑NIR technology for thin‑film measurement and coating‑thickness analysis delivers clear, measurable benefits, including:

• Non‑contact solid‑state NIR sensors with a compact, rugged design that deliver rapid full‑spectrum scanning for demanding industrial environments

• Flexible measurement options, including traveler‑based web scanning or precise statistical spot measurements

• Direct integration with plant PLC or DCS systems for instant or automated process adjustments

• Significant reductions in laboratory testing and analysis, saving time and operational costs for manufacturers worldwide
