The diverse quality of the SWIR lens helps a lot in different work operations and saves quality time, and delivers high-end work quality. The details and accuracy are the prime reasons for the high usage of the lens.
However, before diving into the application and the advantages of the SWIR fixed lens, let’s have a quick go through its features.
Features of the SWIR Lens
The high-resolution imaging delivering capacity of the lens is the primary reason for such large applications. The addition of such premium features of the Shortwave infrared (SWIR) is well-researched and equipped. Whether it’s machinery work supervision or electronic board inspection, all are possible due to the unmatched integrated feature of the lens.
The following table talks about the technical configuration of the SWIR lens:
| Focal Length | 25mm |
| Mount Type | Bayonet |
| Circular FOV | 47°(D) |
| Spectral Range | 1.5–5μm (SWIR) |
| Focus Type | Manual Focus |
| Back Focal Length | 39.4mm |
| Detector | 1024×768 – 17μm |
All the parameters and the measurement of the lens can be changed as per the requirements. The key features of the image, the fixed focal length lens, are as follows:
- High Transmission
- High-end Resolution and Low Distortion
- Low Levels of Scattered or Stray Light
- High Precision Focus
- IR materials: Zinc Selenide, Germanium, Sapphire, Silicon, Chalcogenide, etc.
Advantages or benefits of SWIR Lens
SWIR offers a huge range of advantages. Among all, one of the top advantages is that it easily distinguishes identical objects in the visible range. It helps a lot in figuring out the objects or actions that aren’t visible with the naked eye. It offers advantages in figuring out the object and its details from a long distance in daylight to full night.
To dig in more deep, let’s have a closer look and the multiple major benefits of the SWIR lens:
1. Distant images
Due to the spectacular optical penetration power with minimum light scattering effect, fixed focal length lenses are fully capable of delivering long-distance images. Objects that are blurred with the naked eye and the normal visible lens can be easily viewed by the SWIR optical lens. Therefore, it makes it highly adoptable across various workforces.
2. High Transmission
The lens has a wider gap, which enables it to capture more light and create a shallow depth of field. It makes the lens imaging through special materials like silicon and allows for applications in detecting different kinds of flaws in the products.
3. Minimal Distortion
The fixed focus length is designed and prepared in such a way that it captures all rays of light passing through it. It minimizes the image distortion problem. Due to this feature, it is being used where precision viewing is required, such as seeing parts of a machine, workings of the whole system, etc. This way, it doesn’t lose any details of the object or the viewing scene.
4. Affordable
With top-notch features like delivering sharper, lighter, and clearer views, SWIR lenses are also quite affordable. Once you integrate it into your working operation, it will deliver the required details with optimum quality. Also, SWIR lenses are optimized for the SWIR spectrum, which is a big plus.
Application of the SWIR fixed focal length lens
Due to the high-end and versatile features of the SWIR focal lens is highly used in a large range of industries. Industries like transport, construction, development, electronics, and security. The prime reason is that the ability to capture images in the short-wave infrared spectrum makes it highly applicable.
Here’s a details look at the application of the SWIR lenses:
1. Security and Surveillance
Security is something that is at stake, especially nowadays. Clear view and security are very important regardless of international, national, or domestic location. It ensures safety from the external body, working operation efficiency, and the flow of the overall workplace. The following are some of the prime applications of the SWIR in security and surveillance:
a. Perimeter Monitoring:
Short-wave infrared camera lens are highly capable of working in night vision. They allow for surveillance and ensure safety in low or even complete darkness. It is an advantage of this lens over the visible light cameras.
b. Borders and Ports Security:
Borders and ports are quite sensitive areas in terms of life, area, and product security. Most of the undesirable activities happen in odd and unfavorable visions. It can be due to night, smoke, and fog, although with a SWIR fixed focal length lens, you can easily control and optimize in place.
c. Micro management
Even the running or working of a machine or its parts needs supervision. Doing it all manually is quite exhausting and costly, but with a fixed focal length lens, you can easily check and shoot any issue in the first seconds itself.
2. Inspection and Quality Control:
Any work workforce, whether it’s on a large scale or undergrowing, needs full control over the process and quality control of their work. It can be any product or service across any industry. Some of the major industries where it’s used at a large scale are: solar, electronics, medical, astronomy, etc.
SWIR lenses are frequently used in solar cell testing and electronic board inspection. Both industries keep producing products at a large scale, so they need sharp observing eyes. It is used in finding imperfections in solar cells that aren’t visible to the naked eye. While the SWIR imaging lens ensures the defects on the electronic board, leading to improved quality. It is also used in the light life activity, such as checking the quality of the fruits, whether there are any spots or damage on the fruits or not.
3. Biomedical Imaging:
The healthcare sector always needs a clear and high-end precision view of different parts of the human body. It helps the medical professional a lot in diagnosing diseases and developing a treatment plan accordingly. Short-wavelength infrared (SWIR) penetrates the tissue to provide deeper and clearer images of the targeted human body part. It transforms the working speed and efficiency of the working professional.
The following are frequent uses of SWIR lenses in medical care:
- Viewing blood vessels
- Studying cellular processes
- Observing blood flow
- Movement of the muscle tissues
4. Space Technology
Space is one of the most uncertain and unpredictable industries. There is always a need for sharp and precise views for any observation or development work. Most of the observation happens at night. They need a clear frame, the camera lens fails even in partial light.
It is where a highly transmissive featured SWIR camera lens plays the role. It delivers a distant view even on a heavy night. So, whether it is surveillancing space activity such as planet movement, comet strike, or observing the atmosphere, all can be efficiently done by the SWIR lens. It has been widely accepted as a great solution for getting night vision and acknowledging what’s going on in real time.
