Referred to as liquid glue, UV glue curing is a superior bonding method although this is really a polymer, rather than a glue.  This polymer is often in a silicon glue form, an epoxy, polyurethane, or other polymer that will dry clear only when exposed to UV light.  The UV wavelength is a catalyst for a photochemical reaction which causes the polymer to harden, almost instantly.  In most cases, the polymer will harden when exposed to UV light for only three seconds, although some applications may recommend exposure for ten to fifteen seconds providing optimum bonding adhesion.  This is still considerably less time required for curing polymers than other methods, providing maximum efficiency in several adhesion processes.

Some common examples in commercial applications would be windshield repair or fixing leaking pipes.  Manufacturing processes include assembly lines with parts undergoing UV glue curing in automotive applications such as curing inks on knobs or buttons for interior visual parts.  The gloss provided by the UV process is superior to none, providing clear and shiny print that is resistant to scratching and staining or fading.  The ability to apply this process to three-dimensional parts is advantageous providing speed and efficiency to many manufacturing assembly lines in the automotive and electronics industry.

UV glue curing is gaining popularity over other methods of bonding such as drying or exposure to chemicals, growing at a rate of 10% per year.  Bonding with heat or drying works by evaporation, which can be inconsistent and can also take time for the inks to dry.  Chemical treatment can be costly to purchase materials, and may expose employees to harmful inhalants or respiratory contaminants.  UV glue curing is quick and consistent, providing and instant hardened surface with no harmful chemical exposure.

One big advantage to the finishes with UV curing is that it dries clear, allowing multiple layers if need be while sanding down the finish will provide an invisible ‘liquid plastic’ unbreakable bond.  Paint or stain can be applied to the finish, giving endless options for applications with various products.

Improved quality is one of the biggest benefits realized with UV glue curing over other methods, as a consistent process equates to improved quality.  With UV curing there is no loss of volume or thickness as with drying methods causing evaporation.  The more consistent UV curing process also means reduced scrap, which is another goal for improved quality.

whenwill an understanding of planes of focus and depth of field be valuable in the laboratory?

Whatever the polymer used, the glue will not harden until exposed to UV light.  This is advantageous over substances such as instant super glues that can stick to fingers or other areas not meant to be bonded together.  With UV polymer or glue curing, the bonding area is targeted, drying instantly only in the area meant to be bonded.  The photochemical reaction occurs when the polymer, or glue, is exposed to UV light at particular wavelengths occurring between 240 Nanometer (nm) and 270 nm and 350nm to 380 nm.

When drawing what you see under the microscope, follow the format shown below. It is important to include a figure label and a subject title above the image. The species name (and common name if there is one) and the magnification at which you were viewing the object should be written below the image. All relevant parts of the drawing should be labelled on the right side of the image using straight lines. Lines should not cross. Drawings should be done in pencil, while labels should be in pen or typed. Remember that total magnification is determined by multiplying the ocular x objective.

As magnification increases does the amount of light increase or decrease

Reduced labor is an advantage, along with reduced set up time and reduced clean up time.  A UV polymer curing station would carry a small footprint, not taking nearly as much space as an alternative curing station.  Combined with the high yield enjoyed with this process, the efficiency of UV curing pays with a quick return on investment.

The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.

what is the relationship between plane of focus, depth of field, illumination, and magnification?

The compound microscope is a useful tool for magnifying objects up to as much as 1000 times their normal size. Using the microscope takes lots of practice. Follow the procedures below both to get the best results and to avoid damaging the equipment.

The benefits of UV glue curing are evident just from the increased productivity.  The speed at which parts can be cured is a huge benefit, as increased efficiency equals increased profits.  Products speeding by on a conveyor belt undergoing a superior bonding process while on their way to a packing or inspection station is a big time-saver over a lengthy chemical treatment or drying station, thus reducing labor or additional process stations.

Stronger parts, with improved scratch resistance and enhanced gloss are also additional benefits with this enhanced curing process.  UV glue curing provides an unbreakable bond, with improved part visual appeal and functionality.   All of this happens with an environmentally friendly process and no harsh chemicals.

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. A common exercise to demonstrate depth of focus involves laying three different colored threads one on top of the other. As the observer focuses down, first the top thread comes into focus, then the middle one, and finally the bottom one. On higer power objectives one may go out of focus as another comes into focus.

UV curing of glues and polymers is used in a vast number of commercial, industrial and even residential applications.  Some applications that utilize UV glue curing include:

In some cases, a second layer can be applied, providing even more strength for an unbreakable bond.  This UV glue curing process can be used on almost any substrate, bonding plastic, glass, metal and wood, and even glass to glass, or any variation imaginable.  This versatile process can even be applied to three-dimensional parts, saving time and money with quick all over curing.
