Laser Wire® Cable is only 1mm in diameter; it blows away Fiber Optic Lights and EL Wire in brightness, flexibility, integration and much more.

The name came after the 1801 discovery that sunlight sent through a prism has an invisible component beyond the violet end of the spectrum, causing a reaction in silver chloride solution that darkened it even more than visible light.

The cellular security camera systems work as an excellent alternative to traditional wireless security cameras that need network for data transferring. These cameras, instead of going for an internet connection, transmits video signals over a mobile network. This makes it...

Blue and almost-UV LEDs often emit over a broad range tapering off into the visible, but narrow wavelength 405nm deep blue laser diodes are now in consumer electronics. Yellow glasses will improve the viewing contrast, and these solid-state sources can reveal unique fluorescence responses in the visible range.

Shortwave ultraviolet is emitted by the sun, but it is stopped in the upper atmosphere of the earth by the ozone layer. Shortwave ultraviolet readily causes delayed skin and eye burns, so even indirect exposure should be minimized, especially to high power SW UV lights.

Driven by a fascination for cutting-edge technology and a passion for providing exceptional customer service, Edwina “Eddie” Reynolds has spent over 25 years as a leading figure in the video security industry.

It's a high powered LED cluster, you need to power it with 9-12V and 100mA of current, the metal body acts as a heat sink. Then, installation is a breeze.

“Blacklight blue” fluorescent bulbs are safe and cheap ultraviolet lights. The amount of unwanted visible violet light emitted is determined both by the quality of the visible light blocking filter (which is sometimes integrated into the bulb), and also the source (fluorescent lamps with special UV phosphors emit much more UV than a glowing filament.)

IR illuminators are designed to work in conjunction with B&W or True day / night cameras providing a light invisible to the human eye but fully visible to the CCTV camera. They pick up images clearly without attracting attention to the camera as there’s normally nothing more than a very dim glow on the unit.

Extreme ultraviolet is also emitted by the sun, but is also stopped by ozone in the upper atmosphere. That ozone (O3) is formed from atmospheric oxygen (O2) molecules split by the higher energy UV in sunlight, which accounts for the ozone holes forming during the dark polar winter.

Visible light can cause luminescence; shine a pure violet light at a ruby, and it will glow red, as it has absorbed the violet light energy and used it to create red light. But light-induced luminescence is uncommon and hard to see.

In the medical realm, longwave UV is tradititionally filtered through Woods glass in a Woods lamp named after its inventor, but now using the same technology as high quality longwave mineral lamps. Longwave LED lights are becoming more popular as they increase in power and improve the focus of the UV light into a beam.

Just as the human eye relies on the presence of an adequate light source to see, security cameras must be provided with proper illumination to capture high-quality images and video. Find out how iluminar’s superb external lighting can bring your security and LPR solutions to the next level.

Midwave ultraviolet is also part of sunlight. The body produces vitamin D using midwave UVB. UVB is notorious for causing sunburns, but also activates (melanocyte) skin cells that use longwave light to make melanin, which tans the skin and helps to protect against sunburn.

EA Johnson — Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, it is either transmitted, reflected, absorbed, ...

It is this high ozone layer that stops part of the sun’s middlewave ultraviolet rays and all of its shortwave ultraviolet rays, and which may be in danger from some commercial chemicals. Also called Vacuum UV because it forms ozone at wavelengths below about 200nm which blocks it own transmission through air, extreme ultraviolet extends to soft X-rays in frequency, and the equipment is typically found only in laboratories.

Far-UV region

Midwave, especially shorter wavelengths, is almost completely blocked by common glass. Since midwave ultraviolet is passed by shortwave ultraviolet filters, and UVB tubes have recently become more available, many collectors are using midwave to study mineral fluorescence.

The notations LW, MW, and SW are most often used by minerologists, with the bands generlly centered around the mercury gas emission lines of 365nm, 311nm, and 254nm. The UVA, UVB and UVC notations are very similar, though UVB is generally centered around the 300nm peak of the biomedical action response curve.

If you have a shelf or corner that needs accent lighting, try our Bar light. This slim bar radiates plenty of colors and is easy to fit in small spaces.

Longwave ultraviolet is part of sunlight. It is the lowest-frequency ultraviolet, and thus the nearest to visible light. Longwave ultraviolet passes easily through most transparent types of glass and plastic, and longwave ultraviolet lights are the most durable and readily available.

Visible light is a form of electromagnetic radiation. Other forms of electromagnetic radiation are like light in many ways; they are just at different wavelengths that the human eye cannot see.

It is common for diagrams to show longer wavelengths on the left, because shorter wavelength light has higher energy photons.

UV light

The form of electromagnetic radiation that is most easily used to observe fluorescence is ultraviolet radiation, as generated by a “black light” or UV lights. Ultraviolet is shorter than visible light in wavelength.

Radio and infrared supply too little energy concentration to cause visible luminescence. X-rays cause many dramatic luminescences, but X-ray sources are too expensive, not portable enough, and require too much shielding and attention to safety for ordinary use.

Since wavelength is what makes the difference between colors in visible light, you might say other wavelengths of electromagnetic radiations are “invisible colors of light”. Radio, infrared, visible light, ultraviolet, X-rays, and gamma rays are all forms of electromagnetic radiation.

Shortwave ultraviolet causes slow failure of the filters currently used in shortwave ultraviolet lights through a process is called solarization. Shortwave ultraviolet is the most popular for seeing mineral fluorescence, and the higher photon energy causes fluorescence in perhaps 90% of fluorescent minerals.
