  • Case Study

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?”
  • Article (Technology)

Boresight Stabilization™

Lenses designed with Boresight Stabilization™ can enhance survivability, reduce pointing error, and improve MTF stability.
  • Article (Technology)

Lens mapping function and distortion

The concept of distortion describes how a lens maps a shape on the object plane to the image plane while assuming other aberrations are negligible.
  • Article (Technology)

The Advantages and Disadvantages of Stopping Down a Lens

One modification that is commonly requested by our Customers is changing the F/# of a standard lens.
  • Article (Technology)

Tailored Distortion®: Distortion Correction at the Speed of Light

Tailored Distortion® is an innovation from Sunex to manipulate the distortion to achieve the best image quality in accordance with a client’s requirements:
  • Article (Technology)

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

A hyperspectral lens (also “Day-Night” or RGBIR) refers to a lens that has been optimized to maintain performance throughout the VIS and NIR bands.
  • Case Study

Automotive Camera Trends Driving Changes in Optical Designs

The imaging applications in the automotive industry go through rapid changes.
  • Article (Technology)

“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.
  • Article (Technology)

Why is lens design so hard?

The difficulty arises primarily because of all the trade-offs involved in a lens design namespace constraint, performance targets, and cost.
  • Article (Technology)

What is Active Alignment?

The value of Active Alignment (AA) lies in compensating for sensor plane to image plane variance in up to 6-axis..
  • Article (Technology)

FOV Cone for Housing Design- Why the “Edge Ray Entrance Pupil” is Important

By definition, the entrance pupil of a system is the image of the aperture stop as seen from the object side of a lens system.
  • Article (Technology)

What is the operating temperature spec for a glass/plastic/hybrid lens?

The index of refraction is a function of temperature and nearly all optical systems experience some performance degradation over temperature.
  • Article (Technology)

NoGhost™ lenses reducing optical noise

The following comparison demonstrates the advantages of a NoGhost™ lens that is optimized to eliminate or minimize optical noise.
  • White Paper

Optical Tolerances – Part 2

The modulation transfer function (MTF) is a quantitative measure of image quality describing the ability of a lens to transfer object contrast to the image.
  • White Paper

Optical Tolerances – Part 1

Tolerance is a critical factor impacting the performance and cost of an optical system, hence optical components usually require much tighter tolerances.
  • Article (Technology)

Plastic vs. Glass Optics

Glass and plastic optics each has its own unique advantages. The properties of glass materials are very different from those of plastic materials
