Experts caution those watching the eclipse to be careful: it's never safe to look directly at the Sun. Doing so can permanently damage your vision. Except for a brief moment during the totality when the moon completely blocks out the Sun's rays, you should wear specialized eye protection when viewing an eclipse.

Some application fields and inspection solutions require NIR for high wavelengths as well as for normal lighting, to record high-contrast images. Standard industrial cameras quickly reach their limits in that particular scenario, since they require very good lighting conditions to capture useable images. Setting up these light solutions adds tremendous cost and complexity, which in turn leads to rising system costs and deterioration of the price/performance ratio. Industrial cameras with NIR-optimized sensors greatly simplify life for manufacturers facing inspection tasks of this type.

“Near-infrared” (NIR) is the portion of the electromagnetic spectrum directly adjacent to the visible range; therefore it cannot be perceived with the human eye. NIR-optimized industrial cameras are popular for applications that need to utilize this wavelength range, e.g. applications with poor light conditions, such as traffic monitoring. Until now, these applications were only possible with infrared cameras with expensive CCD sensors.

Now, new CMOS technology can do the job, providing sensors with increased sensitivity in the near-infrared range over 850 nm. It achieves this through the application of a thicker substrate layer (as compared to a monochrome sensor) for the visible spectral range. The new CMOS technology has made NIR optimization affordable, through a line of industrial cameras with excellent sensitivity in the near-infrared, which in turn has boosted their share on the machine vision market.

If you don't have solar glasses yet to watch the total eclipse happening April 8, not to worry. The good folks at NASA have an easy way you can view the eclipse by making a box pinhole projector with common items found around your home — no degree in rocket science required.

Typical application examples are traffic monitoring installations that need to work in poor lighting conditions and at night, fruit and vegetable inspections to detect damaged spots using location-sensing spectroscopy, and the inspection of solar wafers through electro-luminescence.

To use your box pinhole projector, stand with your back to the sun, then hold the large square hole up to your eye and move the box around until sunlight enters the tiny hole in the aluminum foil. In a moment, you should see the sun projected onto the white paper inside the box.

A rare total solar eclipse Monday is set to chart a 115-mile-wide path over portions of Mexico, the United States and Canada. Millions of people are expected to flock toward the path of totality where they can catch a glimpse of this once-in-a-lifetime spectacle.

The NIR-optimized cameras with NIR-optimized 2 MP (CMV2000) and 4 MP (CMV4000) sensors from ams, or the 1.3 MP sensor (EV76C661) from e2V, still manage quantum efficiencies close to 40% in the 850nm range. Compared to non-NIR-optimized cameras, this represents a doubling of the sensitivity value at this wavelength.
