Optical lens is an important part of infrared thermal imaging equipment, as a lens used in the middle wave infrared spectral range, the middle wave infrared optical lens generally works in the 3~5 micron band, its characteristics are also more obvious:
1. Good penetration and adaptability to complex environments. The medium wave infrared optical lens can transmit the medium wave infrared light efficiently and has a high transmittance. At the same time, it has less impact on atmospheric humidity and sediment, and can obtain better imaging results in atmospheric pollution or complex environments.
2. With high resolution, clear imaging. The medium wave infrared optical lens has very high mirror quality and shape control, high spatial resolution and image quality, and is able to produce clear and accurate imaging for applications requiring clear detail.
3. High transmission efficiency. The medium wave infrared optical lens can collect and transmit the medium wave infrared radiation energy efficiently, and provide high signal-to-noise ratio and high detection sensitivity.
4. Easy to manufacture and process, cost saving. The materials used in mid-wave infrared optical lenses are more common, generally amorphous silicon, quartz, etc., which are easier to process and manufacture, and relatively low cost.
5. Stable performance, relatively high temperature resistance. Medium wave infrared optical lenses can maintain stable optical performance at relatively high temperatures. As a result, they are generally able to withstand higher temperature fluctuations without significant deformation or distortion.
Medium wave infrared optical lenses have a wide range of application scenarios and are used in many fields. The following are several common application areas:
1. Security monitoring field. The medium wave infrared optical lens can monitor and monitor the space at night or in low light conditions, and can be applied to urban security, traffic monitoring, park monitoring and other scenes.
2. Industrial testing field. The medium wave infrared optical lens can detect the heat distribution, surface temperature and other information of the object, and is widely used in industrial control, non-destructive testing, equipment maintenance and other fields.
3. Thermal imaging field. The medium wave infrared optical lens can capture the thermal radiation of the target object and convert it into visible images, which is widely used in military reconnaissance, border patrol, fire rescue and other fields.
4. Field of medical diagnosis. The medium wave infrared optical lens can be used for medical infrared imaging to help doctors observe and diagnose patients' tissue lesions, temperature distribution and other conditions, and provide auxiliary information for medical imaging.
