Testimonials

“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.”

When Does a Hyperspectral, or “Day-Night” Lens Make Sense?

Certain applications require a broad spectral operating range and customers oftentimes inquire whether a lens can perform “well” out to their wavelength of interest. These requests typically involve both visible (VIS) and near infrared (NIR) wavelengths.  For purposes of this discussion, a wavelength range roughly from 470nm (or lower) out to about 850-950nm is assumed. Fundamentally, it is important to consider the use-case of the lens and determine how the VIS and NIR wavelengths apply…

Automotive Camera Trends Driving Changes in Optical Designs

The imaging applications in the automotive industry go through rapid changes. Where just a couple of years ago a lens/camera just needed to survive, the expectations moved to better performance, consistent and reliable over a wide temperature range. Below is a video of the talk Sunex presented at the AutoSens 2017 show, sharing experiences and observations on how requirement changes on the camera level impact consideration and design approaches on the lens level. Some of…

“Scaling” as a lens design tool

“Scaling’ refers to a method where a known lens design is proportionally enlarged or reduced geometrically to meet a different image size requirement from what the lens was originally designed for. For example, say, we have a lens that was originally designed for a 1/3” format sensor with an image circle of 6mm, we can “scale” up that design to make the image circle 8mm. This new scaled-up design is now capable of supporting a…

Products & Solutions

Automotive Applications

These lenses are manufactured in our TS16949 certified factory in China for automotive applications. We offer Tailored Distortion™ technology (patent pending) to drastically reduce barrel distortion associated with ultra wide-angle lenses.

Consumer Imaging Applications

These lenses are designed to achieve up to 170° field of view for consumer imaging applications such as sports action cameras. Precision molded plastic aspheric elements are used to reduce optical distortion using Sunex exclusive Tailored Distortion® designs.

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.

Medical Applications

We provide custom optics suitable for limited-use or disposable medical devices. These lenses are designed with bio-compatible materials and are assembled in class 10K clean room environment.

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.

Video Conferencing

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.

Custom Solutions

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.
