The eye is the light of the body as some would say.  Those who are unable to see properly are hazards to themselves.  So, good eyesight will offer you safety.  Poor eye sight can cause you to depend on your glasses to see at all times and this can be a harrowing experience.  The use of eye glasses at all times remove the ease of seeing offered by a functional pair of eyes.  With good eyesight, you will never have to sit close to the front row before you can see clearly in class.  Good eyesight will undoubtedly increase your quality of life.  So, everything you can do to improve your eyesight must be done. If you are having problem with your eyesight, you can get the problem corrected via Aglient UV-Vis & UV-Vis-NIR spectroscopy.

How does it work?

UV-Vis Spectroscopy uses UV ray and the visible region of the electromagnetic spectrum as against the infrared spectroscopy that makes use of the lower-energy infrared region of the spectrum. The wavelength in UV-Vis spectroscopy is measured in nanometers and its range can spans between 100 and 400nm. The Aglient UV-Vis & UV-Vis-NIR spectroscopy is used for measuring light absorption in the eyes. The tool uses light for illuminating a given sample and it will measure the amount of light absorbed into the sample.  Additionally, the tool can measure the amount of light reflected and transmitted by the sample.

Check below for the various applications of the spectroscopy:

• It is reliable for identifying molecules in liquid or solid samples
• It can also help in determining the concentration of a given molecule in solution
• It measures the transmission and absorption of light via solid or liquid across a given wavelength range.
• The tool can equally be trusted for studying biological or chemical processes.

Its main components

The main components of the spectrometer are:

• A source of light generating electromagnetic radiation broadband across the visible spectrum of the UV
• A device for dispersion capable of separating the broadband radiation into wavelengths.
• A sample area from where the light is reflected or absorbed.
• Detectors that can be used for measuring radiation intensity as it is transmitted or reflected.

Light is reflected by other optical components in the spectrometer, fiber optics, mirrors or lenses.  You need a light source that can generate constant intensity across all wavelengths without generating much noise and with assurance of a long-term stability.  Examples of light sources being used are deuterium arc lamp and tungsten-halogen lamp. Some also use single xenon as light source; this last one even has a very wide usage.  All the light sources mentioned above have their pros and cons.  The tool is also not difficult to use at all.
