Short-Wave Infrared or SWIR is an imaging technology that traditionally has been used in biological, defense, and some industrial-related applications. With the ever-growing need for camera systems that can see more than the human eye, engineers turned to the wavelength spectrum beyond the visible (VIS) space. The infrared spectrum from 750nm to 12,000nm is broken down into two distinct sectors. The “reflected infrared” is represented by the Near-Infrared (NIR) and SWIR bands, and…

“We are getting great feedback from the field on the camera image quality, people are saying things like spectacular and magnificent. This, of course, starts with the excellent lens you are delivering.”
“Initial evaluation indicates a contrast of 40-50% with our object. This is better than our requirement of 30%. This is for each of the three images at 520, 550, and 630 nm without re-focusing. This is excellent performance.”
“Thanks guys, I am very satisfied.!!! This lens is a big improvement in our digital product.”

Digital imaging lenses are often made of multiple lens elements to achieve the required specifications. How are those lens elements made in mass production ? The answer to this question depends on the type of element chosen by the lens design engineer. Three types of lens elements are commonly used today. They are polished glass elements, molded plastic elements and molded glass elements. Each type of elements has its own unique process steps and capabilities. …
At Sunex, we get many questions about lens and mount (holder) threads when it comes to board-mount lenses. In this post, we will explore some of the basic considerations of threaded lens and mount combinations, as opposed to some other common methods, which we will touch on. Although this post will not be a detailed tutorial of the mechanical engineering theory of thread specifications, a basic understanding of thread spec and tolerance helps to understand…

Fisheye Lens for DSLR Camera
SuperFisheye® lenses with a field of view of 185 degrees are designed for digital SLR cameras such as the Canon 50D and Nikon D300. These lenses are useful for producing 360 degree panoramic images and fully immersive images (similar to Google Street View). We also provide panoramic rotators and proprietary Dewarper software for these lenses.
Industrial Imaging Lenses
These lenses are used for finite object imaging applications such as face/object recognition, barcode capturing, machine vision, and bio-medical securities. Their small size is compatible with a variety of hand-held products. We can also integrate auto-focus technologies with these lenses.
Security & Surveillance
These lenses are designed for security/ surveillance cameras where low light and day/night operations are important. The lenses have a field of view up to 185 degrees (superfisheye). Certain lenses are also spectrally optimized to cover the visible and the near infrared spectrum (NIR). We also provide day/night exchangers and special IR cut-off filters.
Typical video-conferencing cameras require lenses with high image quality and low distortion. For high frame rates in low light situation, a lens with low f/# is required. We offer lenses with advanced optical technology incorporating high-index materials and aspherical elements in various imager sizes. We also provide IR cut-off filters and optical low-pass filters as part of a complete optical solution.
If off-the-shelf optics does not meet your application requirement, we can also work with you to design, prototype and mass-produce custom optics tailored to your specific needs. We manufacture quality optics in our facilities in China and provide professional support from our USA office.
