Vision

Vision is a sense that allows you to see the world around you. It starts when your eyes detect light, which they then turn into coded nerve signals that travel to your brain. Your brain then decodes these signals to create the pictures you see.

Seeing with your eyes is different from the New Age concept of “visionizing.” The latter refers to a belief that by imagining something, it will manifest in reality. This is not the same as the biblical idea of vision, which is a direct revelation from God.

A digital night vision device’s most important feature is its objective lens, which must offer high light transmittance in the visible and near-infrared range. Luna Optics’ digital day/night devices employ a state-of-the-art f1.0 objective lens, which provides the highest possible image quality. This is critical for the best possible user experience. This level of clarity is impossible to achieve using a traditional analog night vision device.

Objective Lens

The objective lens, along with the eyepiece, is the most critical part of a microscope. It determines the magnification range and focuses light onto the specimen. Each objective has two specifications: magnification and numerical aperture (NA), which indicates the lens’ ability to gather and resolve light.

The optical design of objective lenses has improved over the years as construction techniques have advanced. Modern objectives are made with high-quality glass that offers low dispersion, and they can correct for a wide range of optical artifacts, including field curvature, spherical aberration and chromatic aberration.

Most standard objectives are achromatic, but fluorite and apochromat designs can further enhance color accuracy. They also provide flat-field correction to ensure a crisp focus across the entire visual field, which is especially important for photomicrography and video imaging. Some objectives are optimized for darkfield, which can improve contrast in opaque specimens in fields such as materials science and metallurgy. Others are designed to be compatible with a variety of immersion mediums, allowing one lens to work with water, glycerin or specialized hydrocarbon-based oil.

Ocular Lens

Your eye is enclosed by a tough white sac, called the sclera. The cornea, a transparent dome at the front of your eye, allows light to enter. It also refracts and bends the light passing through it to direct it into your retina. For more details please visit luna805

Your lens is a complex, ellipsoid, biconvex structure that changes shape to focus light rays onto the retina. This process, known as accommodation, allows you to view objects at different distances.

Your iris controls the size of your pupil, which in turn determines how much light gets to your retina. Muscles inside your eye called the ciliary muscle connect on each side of the iris and control the movement of your lens. When you are focusing on near objects, the ciliary muscles contract and your lens zonules (the flexible fibers that support your lens) become steeply rounded. This enables you to see clearly. When you are focusing on distant objects, the ciliary muscles relax and your lens becomes flattened.

Sensors

Sensors sense aspects of the physical world like light, movement, chemical compounds, temperature, force and pressure – just as a human’s five traditional senses do. But they convert this information into electrical signals that are read by a computer or electronic device. They’re everywhere – in automatic doors, in our computers and mobile phones, in doctors offices and hospitals. They’re used in food safety and hazard detection, environmental monitoring and health care. They’re used in factories to monitor the process of making things and on spacecraft to track performance, temperature and air pressure.

Researchers have designed a sensor that’s flexible and stretchable enough to be worn inside the body and sensitive enough to detect the smallest amounts of nitric oxide. The team has built it from materials that can be dissolved in the body or water, so it could help monitor conditions such as Parkinson’s disease or post-operative recovery. It’s also a lot lighter than current implantable sensors.
