We use light to monitor the health of humans and animals

Spectrochemical analysis employing optical spectroscopy methods is used to monitor the water that we drink, the quality of food that we eat, the status of human and animal health, and the quality of the environment that we live in. Optical Spectroscopy is keeping the world healthy and safe.

For example Gilden Photonics supply Raman Spectroscopy systems that can inform you about the state of a human cell. Is it virally infected, it is cancerous, pre-cancerous, or not cancerous? We supply Fluorescence Spectroscopy systems that analyse water quality for the presence of contaminants, or to fingerprint specific hydrocarbons found in sea water, and match them to their source of origin. We also manufacture Hyperspectral Imaging systems that are used by law enforcement organisations for narcotic detection, fingerprint analysis and scene of crime investigations, and Asorbption Spectroscopy Spectrometers for the detection of counterfeit spirits, such as illicit Whisky, Vodka and Gin.

Raman Spectroscopy, Infrared Spectroscopy, UV Spectroscopy, Fluoresence Spectroscopy, Absorbtion Spectroscopy and UV-Vis Spectroscopy are examples of different techniques based on the measurement of radiant power, and in each of these instruments the performance characteristics of the optical source plays a critical role in the acquisition of reliable and meaningful data. The keys to selecting the most suitable spectroscopy light source are spectral characteristics, wavelength range, temporal and spatial stability, radiant flux and directionality.

UV Spectroscopy can be performed using Hydrogen and Deuteriem arc lamps which have a strong emission spectrum in the UV and can be useful from 185 nm into the visible. Shorter wavelength operation is possible by using alternate window materials such as MgF2 which can operate from wavelengths down to 110 nm. Dueterium lamps provide a higher optical output compared with Hydrogen lamps and are the primary light source at wavelengths below 400 nm. Absorption Spectrometers working in the UV and Visible generally use both Deuterium (200 to 350 nm ) and Tungsten lamps (350 to 850nm).

Photoluminescence Spectrophotomers require high-intensity continuum sources with both UV and Visible output and the most common source used is the Xenon sort arc lamp, which has an intense almost continuous spectral output from the UV (200nm) to the Near Infrared (NIR) 800 nm and optical output observed well into the IR (2600 nm). Although typically operated with DC power supplies, pulsed versions are available with 1 to 10 µs pulse widths for use in Time Resolved Spectroscopy measurements. Xenon lamps offer the highest flux density short of a laser, with a spectral output that is close to the sun at 6000° C, and therefore they make ideal solar simulators in many experiments

Line sources are used in many Atomic Spectroscopy applications. The most common are low pressure arc lamps such as Mercury arc. These lamps have sharp atomic line emission and are excellent sources for wavelength calibration of the spectrometer especially in the UV. Hollow cathode lamps have become the dominant atomic spectral line source because they produce extremely narrow atomic lines, typically with widths of 0.001 to 0.002Å .

For a wide range of applications that include miniking the sun, testing the potability of drinking water, collecting scene of crime evidence, healthcare diagnostics and even ensuring that the spirit in your drinking glass is what it is claimed to be, a Gilden Photonics light source is an essential component of any optical spectroscopy system.
