It is an important part of infrared spectral imaging, and their main difference lies in the different wavelength range and lens material. Short-wave infrared lens is suitable for the wavelength range from 1.5 to 2.5 microns, and it is used to detect chemical pollution, electronic equipment failure and geological exploration.
The aperture is designed with multi-blades, which can improve the adjustment accuracy of the aperture and the uniformity of incident light. The lens surface is coated with 0.8~1.8um multi-layer antireflection (AR) film, which has high transmittance and meets the high seismic environment. It is suitable for various short-wave infrared imaging applications such as spot detection, machine vision, industrial inspection, classification and quality control, and is a compact and lightweight lens for short-wave infrared imaging.
Short wave infrared (SWIR) lens technology is making great strides in the world of imaging and sensing, and its effect is nothing short of impressive.
SWIR lens technology is closely related to near-infrared (NIR) lens technology, but it operates in a much shorter wavelength range. This technology is still relatively new, but it has already made a mark in numerous fields, including medical diagnosis, industrial inspection, and security, just to name a few.
The benefits of SWIR imaging are numerous. For one, it is far less sensitive to scattering and absorption in the tested material. This means that it provides a clearer, more detailed image even with highly attenuative materials, such as smoke and fog.
Additionally, SWIR imaging can capture images through painted or coated materials, allowing it to “see” through surfaces. This is particularly useful in detecting hidden defects or objects that are not visible to the naked eye.
SWIR lens technology is also far more sensitive to temperature changes than other forms of sensing technology, which means it can detect minute temperature variations and pick up on things that may be completely missed by other sensors.
In short, SWIR lens technology represents an exciting new frontier in imaging and sensing, with its many advantages pushing the field to new heights. The future of SWIR lens technology looks bright and promising, and its continued development will undoubtedly lead to many beneficial applications in the years to come.
