Infrared quartz glass halogen heating lamps for coating chambers:
Advantages
Fast heating and precise temperature control: IR infra red heater halogen tube bulb can quickly heat the coating material and substrate to the required temperature. Compared with some traditional heating methods, they heat faster. For example, in thermal evaporation coating, they can make the coating material reach the evaporation temperature faster and improve the coating efficiency. At the same time, through the cooperation of advanced temperature control equipment (such as thermostats, sensors, etc.) with heating lamps, the temperature can be precisely controlled with an accuracy of ±1°C or even higher. This precise control is essential for the preparation of high-quality, high-performance films, because different coating materials and processes have very strict temperature requirements.
Good spectral characteristics and heating uniformity: Quartz glass has a high transmittance to infrared rays, so that the infrared rays emitted by the infrared halogen heater emitter can be effectively transmitted to every corner of the coating chamber. Moreover, by reasonably designing the shape, number and position of the Halogen Heating Heater Lamp, relatively uniform heating can be achieved inside the coating chamber. This is very important to ensure the uniformity of the film. Whether it is a large-area substrate coating or a complex-shaped substrate coating, it can be evenly heated to avoid problems such as uneven film thickness and inconsistent adhesion.
Clean and pollution-free heating method: This IR infrared halogen lamp will not produce impurities that contaminate the coating material and the substrate during operation. Unlike some heating methods that use flame heating or other methods that may introduce impurities, IR Halogen Heat lamps are a “pure” heating source. This is very beneficial for the preparation of high-purity, high-quality films (such as semiconductor films, optical films, etc.), because any tiny impurities may affect the performance of the film, such as reducing the transparency of the film and changing the electrical properties.
