Make Use of Fluorescent Illumination and Avoid Damaging

Photosensitive Materials


Are you a photographer looking to develop best quality photographs? Or are you a biologist researching on specimens at the cellular level? If yes, then it is quite obvious that you work consists of dealing with photosensitive materials. And of course, you cannot risk exposing these materials to high intensity light and cause damage to it. It is here that the application of fluorescent light passed through a microscope light source comes into play.


Photosensitive Materials


The first question that must have come to your mind in this regard is what exactly is meant by photosensitive material? Putting it simply, a photosensitive material may refer to a substance that undergoes a change in chemical composition when subjected to electromagnetic radiation. A photosensitive material is prepared by coating a surface with an aqueous solution of slats of alginic acid which in turn is impregnated with an aqueous solution of silver salts. Photographic plates are perhaps the best example of photosensitive materials.


It has been seen that exposure to light, such as, sunlight often damages the photosensitivity of a material. And this damage can lead to a lot of unwanted results in many cases. For instance, hydrogen peroxide that is used in photographic plates gets damaged when exposed to sunlight or some other strong sources of light. In order to prevent this damage, fluorescence illumination and UV Curing techniques are being put to use.


What Is Meant By Fluorescence Illumination?


So, the first and foremost question that needs addressing in this regard is what exactly is meant by fluorescence illumination? Simply put, the term refers to the process by which shortwave light energy is absorbed and converted into long wave light energy. If you are a stickler for the crime investigation series aired on television, you might have noticed the detectives making use of a special form of lighting in order to trace hidden fingerprints, bloodstains and the like. Well, that is what is known as fluorescence illumination. Mostly observed under a black light or UV light, this technique is often used to observe or work with photosensitive materials without damaging them in any way.


Fluorescence illumination has gained a lot of prominence in the recent times, particularly in the study of currency notes and in the production of biological equipment such as fluorescence microscope. These microscopes make use of a microscope light source to illuminate the specimen, thereby making it easier for researchers to study them. This technology has also been put to use in the photography industry to develop photographic plates owing to its sensitivity to light. It might, therefore, be concluded that the technology of fluorescence illumination can be used to avoid damage to photosensitive materials in addition to other applications.


What Is Meant By UV Curing And How Can It Help You?


UV Curing or Ultraviolet Curing is the name given to the photochemical process where high intensity UV lighting is put to use for drying inks, adhesives, coatings instantly. This technique has successfully eclipsed traditional drying options with its effective scratch and solvent resistance methods. It is because of this reason that you will find the photography industry making use of the UV curing lamps in order to develop the photosensitive plates.


UV Curing technology in the form of UV Curing lamps have been widely in use in a number of industries, viz, telecommunication, electronics, graphic arts, glass and plastic decoration and the like. This technology has scored above the conventional thermal drying methods using water and other solvents owing to its increased productivity.
