If you’re an art historian,you may be familiar with the applications of SWIR cameras. SWIR cameras can be used to view the details of pencil or charcoal drawings. These cameras also allow art historians to visually verify the authenticity of valuable documents. Here are some examples. Below are some examples of SWIR cameras. These applications require a camera that is sensitive to infrared light.
Machine Vision Camera
Machine vision applications have many advantages due to the SWIR camera. One of these is improved speed. These cameras can detect objects at speeds up to ninety thousand lines per seconds and operate at standard video rates between 30-60 frames per second. These cameras are capable of full 1024-pixel resolution at 12 bits. They are also remarkably cost-effective. Here are some of the most popular uses of SWIR cameras.
Industrial machine vision cameras are the core of vision systems. As machine vision industries become more sophisticated and cost-effective,machine vision industries are adapting to those changes. In the glass industry,for instance,SWIR cameras can identify and reprocess rejects efficiently. In an industrial setting,SWIR cameras are able to detect the centroid energies of laser spots. The camera can detect the centroid energy and identify contaminated materials.
A SWIR camera can also be used to detect moisture. Since water is transparent to visible light,it absorbs strongly at wavelengths between 1450 and 1900 nm. The SWIR camera detects moisture in coatings and detects fill levels for non-transparent containers. It can also measure the relative water content of plants. The SWIR camera can detect defects in silicon products as well as identify recycled plastics. In addition to these applications,SWIR cameras have optical coatings to improve image quality.
Swir InGaAs Camera
An SWIR InGaAs Camera is a great choice for many defense applications. The uncooled design of the camera is lightweight and sensitive to nightglow. Its high-resolution images can be used to detect laser designators and can be attached to covert eye-safe lasers. Several applications for SWIR imaging include target recognition and laser gated imaging. The advantages of the SWIR InGaAs camera are numerous.
Moisture detection is one of the most popular SWIR applications. Water is transparent to visible light but absorbs strong between 1450 and 1905 nm. This produces an image that appears black. This capability makes it a viable tool for detecting water,as it helps identify areas of water deficiency,as well as areas of excess water. It can be used to determine the relative water content of plants and even detect damaged fruit.
InGaAs cameras are particularly useful in detecting cracks and defects on silicon. Because it can penetrate the in-vivo tissue,InGaAs cameras are essential for humidity measurements,surface film distribution,and material separation. This imaging technology has a drawback: it produces a lot of dark noise that is often more than one wavelength. However,deep cooling reduces dark noise.
Silicon Inspection Camera
Traditionally,silicon surface inspection has been performed using CCD or CMOS cameras. These cameras have a wavelength response of 350 to 1000 nm. Deep-depleted silicon devices provide sufficient quantum efficiency for seeing the shortest wavelengths but require long integration times,and are not suitable for imaging intraband emissions of Si above 1100 nm. This makes them suitable for offline front-side inspection. These are the benefits of Si-based cameras.
A spectroscopic camera is capable of detecting small defects. The polarization of the lens allows for the camera to capture images under polarized light. This is essential for inspection of reflective surfaces. The camera can also be used with single dies or silicon wafers. Another feature that distinguishes it from other cameras is its ESD-safe stand. A SWIR camera’s spectral resolution is three times greater than a standard camera.
A silicon inspection camera is able to detect defects in silicon wafers and solar-cell panels. This improves productivity and yields. The use of InGaAs cameras in silicon inspection applications is a growing trend. InGaAs cameras are especially useful for monitoring wafer bonding processes. It can detect silicon defects even if they are hidden behind the material.
