The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. The typical light source spectrum wavelength ranges from Ultraviolet Light (UV-C: 200 to 280nm; UV-B: 280 to 315nm; UV-A: 315 to 400nm) to Visible Light (400 to 760nm) and Infrared Light (760 to 3000nm). LED UV lights have a narrow spectral output centered around a specific wavelength, ±10nm. Most Phoseon products use 365nm, 385nm, 395nm or 405nm wavelengths. This near-monochromatic distribution (see chart) requires new chemical formulations to ensure proper curing of inks, coatings, and adhesives.

For the purpose of recruiting and looking for a career, optics and lasers go together because of the size of the market for lasers. In 2004, approximately 131,000 lasers and 733 million diode lasers were sold with a value of over $5 billion. Since their invention in 1960, they have become ubiquitous with supermarket barcode scanners and laserdisc players. There are jobs with lasers in medicine (cosmetic and eye surgery), industry (cutting and welding), defense (marking targets and defending against missiles), and scientific research (spectroscopy and interferometry).

Energy density, also called dose or radiant energy density, is the energy arriving at a surface per-unit-area during a defined period of time (dwell or exposure). A square centimeter is again the unit area and radiant energy density is expressed in units of joules or millijoules per square centimeter (J/cm² or mJ/cm² ). Energy density is the integral of irradiance over time. A sufficient amount of energy density is necessary for full cure.

The majority of standard UV curing happens in a narrow emission range with the remainder of the spectral output generating unneeded and potentially harmful UV-C and infrared emissions. UV LED lights provide this narrow emission range.

A job in illumination engineering involves the deliberate application of light to achieve some aesthetic or practical effect. Light sources include artificial light from lamps as well as daylight from windows and skylights. Artificial lighting represents a major component of energy consumption, accounting for a significant part of all energy consumed worldwide. A career in photonics means working on the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. Because there are so many job opportunities in photonics, it can be considered a separate career path.

Since the discovery that light is electromagnetic radiation, optics has largely been regarded in theoretical physics as a subfield of electromagnetism. Some optical phenomena depend on the quantum nature of light and the interaction of light with matter. Geometric optics and physical optics are models that describe phenomena while ignoring properties of light that are insignificant for the system of interest. A job in optical science might require a background in electrical engineering, psychology, and medicine (particularly ophthalmology and optometry).

Peak irradiance, also called intensity, is the radiant power arriving at a surface per-unit area. With UV curing, the surface is the cure surface of the substrate or part, and a square centimeter is the unit area. Irradiance is expressed in units of watts or milliwatts per square centimeter (W/cm² or mW/cm²). Peak irradiance is instrumental in penetration and aiding surface cure. Peak irradiance is affected by the output of the engineered light source, the use of reflectors or optics to concentrate or contain the rays in a tighter surface impact area, and the distance of the source from the cure surface. The irradiance for UV LEDs at the cure surface decreases quickly as the distance between the source and the cure surface increases.

There are two key parameters of an LED lamp that should be understood for the purposes of optimizing cure and establishing a process window. Identifying this process window will result in the most durable and desirable finish, as well as acceptable adhesion and surface cure: peak irradiance and energy density.

Careers in optoelectronics require an understanding of the quantum mechanical effects of light on semiconducting materials. Optoelectronics is the study and application of electronic devices that produce, detect, and control light. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. There are jobs in the design and manufacture of devices that use the photoelectric or photovoltaic effect. Such devices are photodiodes (including solar cells), phototransistors, photomultipliers, and elements for integrated optical circuits (IOC). The phenomena of photoconductivity is used in photo resistors and charge-coupled imaging devices. The phenomenon that is the basis for lasers is stimulated emission.

UV LED curing light sources efficiently convert 20-40% of the input electrical power into usable UV light with no harmful UV-C or infrared exposure. That efficiency translates into approximately 80% power and heat savings over mercury based lamps.
