These elements operate between 1200-2000°C, depending on the coating material being evaporated. Tungsten-based elements can reach up to 2000°C, while molybdenum elements typically operate up to 1700°C.
Temperature uniformity directly impacts film thickness consistency and adhesion. Non-uniform heating causes uneven evaporation rates, leading to thickness variations and potential defects in optical coatings.
Regular inspection for material degradation, cleaning of contamination, and resistance measurement. Elements should be replaced when resistance changes by more than 10% or when visible deformation occurs.
