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.”

Cleaning Procedure for Optics

The general guideline for cleaning optics is “if it’s not dirty, don’t clean it”. Handling optics increases their chances of getting dirty or damaged, so you should clean optics only when necessary. Both the proper cleaning products and proper methods are equally important to cleaning the optic. There are different methods for cleaning and certain specialized optics require particular attention and change in procedures. Below are general guidelines to be used as a reference only…

Lens Customization- What You Need to Know

One of the questions we frequently get at Sunex is some variation of, “Can I modify a standard lens, and what does this entail?”  The answer to this question is, “Yes!” depending on what you would like to modify, of course!  In general, there are four categories of what can potentially be modified on a standard lens: External Mechanical Features Coatings/Filters F/# Specifications While first-order lens parameters which are inherent to the optical design typically…

Boresight Stabilization™

A typical lens assembly consists of several lens elements inside a cylindrical barrel.  Due to the mechanical clearance requirement, the internal element diameters must be smaller than the barrel internal diameter. This creates potential risks that could result in boresight errors or changes: Lens to lens variance of the optical axis due to manufacturing tolerance A possible lateral shift of individual elements overtime due to strenuous conditions The first potential risk (lens to lens variance)…

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.
