However, it also has downsides and negative effects for human health. Because blue light is so bright, with a higher color temperature than daytime sun, it makes your brain and body think it’s time to be wide awake. So if you take in too much blue light at night, you can knock your circadian rhythm out of balance and develop sleep problems. [4], beyond potential risks to your eyes [5].

Light is electromagnetic radiation, in the form of a wave. You can think of light as energy that travels through the air with a specific frequency, or wavelength. The shorter the wavelength, the more energy the wave contains; the longer the wavelength, the deeper the wave can penetrate into human tissue. Wavelengths of light are measured in nanometers (nm). A nanometer is one billionth of a meter, or 0.000000001 meter.

As you can see on our wavelength chart, the spectrum includes both visible light that humans can see, like red and blue light, and also invisible light like near infrared (NIR) light. Visible color in light comes from the length of the wave and how our eyes perceive it. The energy in light is dependent on the wavelength and  color is how the human eye and brain understand of light’s electromagnetic wavelengths. The visible spectrum of light makes up a very small portion of all electromagnetic radiation.

Image sensors such as CMOS have seen their use cases grow significantly in size across many industries today. And you can also see major differences among the designs of the image sensors. For instance, these sensors come in varying sizes.

The existing body of research on light and human health shows that red and NIR light are the most beneficial wavelengths, with the fewest risks and downsides. UV light is crucial for vitamin D, but it can also be dangerous when you absorb too much. Blue light similarly has upsides and serious downsides. Red and NIR light have shown a wide range of potential health enhancements, with relatively little risk and few side effects.

AR0234 from Onsemi is one of the most popular sensors used in such applications.

Near Infrared (NIR) Light: Near infrared light (in the mid-700 to 1000s nm range) has a much longer wavelength than the previous colors we’ve mentioned. That allows wavelengths of NIR light to penetrate deeper into the body, for further-reaching deep tissue healing and regenerative effects. NIR light can support muscle health and enhance the body’s natural recovery and healing processes. You can see more about how Joovv uses pulsed NIR light for Recovery+ mode here.

2022720 — But a light diffuser does the opposite — it blocks or reflects part of the light, but still allows enough to properly light a subject or scene.

Resolution is the ability of imaging systems to reproduce the exact object detail. Many embedded vision applications like autonomous mobile robots (AMR) and autonomous vehicles demand cameras to achieve precise 3D depth measurement. This would be achieved with the high-resolution feature of that camera. Selecting sensors with large pixel sizes is likely to have higher resolution.

Also, the resolution of the lens must match the pixel size of the sensor to achieve high-quality images. The quite popular camera resolution of 1600 x 1200 pixels often uses a larger sensor with a size of 1/1.8″, and now high-end 4K resolution uses a 1/1.2″ image sensor format.

Thanks to today’s LED technology, Joovv is able to isolate specific wavelengths of red and NIR light and deliver it directly to the skin and cells. Red light therapy is essentially taking the most beneficial wavelengths of light we get from the sun, and avoiding everything else, so you can target the mitochondria and enhance cellular function and energy production across the body. In conjunction with a healthy lifestyle, absorbing red and NIR light supports biological balance and overall health.

Yellow Light: Like green light, yellow light is still being researched and explored by scientists. Yellow light is in the 570-590nm range, and early studies have pointed to potential benefits related to skin health, but more studies are needed to draw conclusions. [7]

Light is essential for all life on earth. It’s fundamental to human health, and light is a key component of a balanced lifestyle, just like diet, exercise, and sleep. But light is often overlooked as a major contributor to health and well-being. And most people don’t get nearly enough sunlight: the average American spends over 90% of their time indoors, surrounded by bright artificial light. [1]

Blue Light: One of the most commonly isolated wavelengths of light is in the 380-500nm range, which our eyes perceive as very bright blue light. Blue light is isolated and used in most of our modern screen technology, from TVs to phones to tablets to computers. Blue light is very good at illumination, and an efficient source of light for electronics. It’s also been found to have some positive effects for bacterial acne and teeth whitening.

Industrial cameras might have issues like lens vignetting/lens shading, which is a gradual reduction of an image’s brightness or saturation from the image center to the four corners/ edges. This happens when the image format (or circle) of the lens is too small for the size of the sensor. So, to mitigate this, the image circle diameter must fit or be larger than the sensor size.

Light is key to all life on earth, and it’s essential for human health and function.  Most people don’t get nearly enough light from their environments, which can have negative health consequences. Red and NIR light in particular has been shown to enhance cellular function, and support healthier sleep, skin, and recovery.
