APC’s coating laboratory integrates advanced instrumentation to measure transmission and reflection across wavelengths from the visible spectrum through the far infrared. A custom-built vacuum laser calorimeter enables precise absorption measurements for CO₂ lenses and mirrors.
All coating and inspection processes are conducted within custom-built DynaVac chambers housed in a Class 10,000 cleanroom, ensuring consistent quality and optimal optical performance that meets or exceeds customer expectations.
APC utilizes Essential Macleod thin-film design software to optimize the performance and efficiency of infrared optical coatings. With extensive in-house expertise, APC develops fully customized coating solutions tailored to unique application requirements and evolving market demands.
Laboratory Equipment
- Infrared Spectrophotometer (PerkinElmer Frontier Optica) – Reflection and transmission measurement
- UV-Visible Spectrophotometer (Shimadzu UV-1601) – Reflection and transmission measurement
- Laser Calorimeter – Absorption measurement at 10.6 μm
