Innovation, Performance, Support and Value
Sunex specializes in high-performance lenses and customized solutions from design to manufacturing. We have built a high quality manufacturing organization (ISO9001, ISO14001 and TS16949 certified) enabling us to deliver cost-effective optics flawlessly manufactured with outstanding reliability to customers worldwide. We take pride in providing in-depth technical support to our customers.
“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.”

New technologies, new application requirements, and new market segments are challenging every automotive vision program to consider and balance performance vs. cost, glass vs. hybrid, and off-the-shelf vs. custom design. Taking a platform approach at the lens component level can deliver quality optics in support of faster innovation cycles, increased manufacturability, and optimized lifetime cost and reliability at the system level.Before we answer, how Sunex arrived at the concept of an Automotive Digital Imaging Optics…
It is well-known that the magnification of an imaging lens changes with the object distance (distance from the object to the lens). However it is less known that the magnification changes with the field angle as well (i.e, where in the field the object is placed). Additionally the off-axis magnification can be asymmetric. In other words, the tangential and sagittal magnifications can be different. This causes shape deformation for off-axis objects. For example, a golf…

Products & Solutions
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.
