How is the performance of an IR lens evaluated?
The performance of an infrared lens is evaluated by several parameters. Modulation Transfer Function (MTF) is an important indicate that measures the lens's ability to transfer contrast from the object to the image plane at different spatial frequencies, indicating the sharpness and clarity of the image. Another parameter is the focal length, which determines the magnification and field of view of the lens. The aperture or f-number affects the amount of light that can pass through the lens and thus the brightness of the image. In addition, factors such as chromatic aberration, distortion, and the lens's ability to maintain focus over a range of temperatures also play important roles in evaluating its performance.
How to ensure the quality of infrared lenses during the manufacturing process?
During the manufacturing process of infrared lenses, strict quality control measures are essential. This includes precise grinding and polishing of the lens surfaces to achieve the required curvature and smoothness, which is crucial for accurate focusing and minimizing light scattering. High-quality coating processes are also necessary to apply anti-reflective coatings that enhance the infrared transmission and reduce unwanted reflections. Meticulous inspection and testing at each stage of production, such as using interferometers to measure surface accuracy and another testing equipment to evaluate optical performance, help to identify and correct any defects or deviations from the required specifications. Additionally, maintaining a clean and controlled manufacturing environment is important to prevent contamination that could affect th
