Illuminated displays used in the marine industry, like those in the automotive and aerospace industry, have to remain clear and readable in all kinds of weather, day or night. They also have to be resistant to water, dusty, vibration, and all the other harsh conditions of life at sea, and require rigorous quality testing to adhere to safety and operating standards.

Photometry is the science of measuring light as it is perceived by the human eye, and colorimetry applies the same principles to measuring the different wavelengths of light based on how we perceive color. Learn how humand vision is quantified and replicated in photometry-based imaging systems, and how these systems can help manufacturers in design and production to best assess the visual quality of displays, backlit components, and light sources as they are actually seen and experienced by users.

Electromagnetic radiation from the sun--including both the visible light spectrum, and invisible wavelengths such as infrared and ultraviolet--is all around us. Recently scientists have found many uses for certain parts of the light spectrum, such as tapping into the UV spectrum's ability to kill germs, and the beneficial effects of certain green wavelengths to humans.

The interior lighting of an automobile has both a functional and aesthetic purpose. Ambient light can affect driver focus and thus safety, and lighting features like buttons and controls can make it easier to operate a vehible at night. With the advent of LEDs and other new technology automotive designers are creating new and innovative lighting approaches—that must be rigorously tested to conform with industry standards.

Human vision is one of the marvels of the natural world—we can see detail in high resolution at near and far distances with accurate depth perception. We also have a high sensitivity to color across the spectrum of electromagnetic light from wavelenghts of roughly 380 to 740 nm. How does what we see compare to various members of the animal kingdom? And how do we measure and quanitfy vision and color perception? Read more...

Todays consumers expect the highest quality from devices like smartphones, televisions and laptops—and not only for diplay screens the but for keyboards. Manufacturers of laptops and keyboards need to perform precision visual inspection of these devices during the assembly process to ensure that defective products don’t end up in customer hands. Cosmetic flaws and performance failures can result in rapidly escalating direct and indirect costs due to warranty claims, returns, and damage to brand reputation.
