This radiation is potentially the most damaging because of its high energy levels.  Fortunately, at this time, all UVC is absorbed by oxygen and ozone in the atmosphere and never reaches the Earth’s surface. Glass reflects UVC light.

Cleaning window film on the inside of the glass requires a bit of care, but nothing special. Our films are almost as hard as glass itself and resist scratching. We recommend cleaning the film with a micropore cloth and mild soap. Avoid using household cleaners, and especially ammonia-based cleaning products, abrasive cloths, or scouring pads.

On top of this, harmful UV radiation from the sun coming through your glass is the leading cause of premature fading of furniture, curtains, wooden floors, carpets, rugs, artwork, etc. This has the potential to damage people as well. We have the solution – our solar window film blocks almost all UV rays.

We recommend and install top-quality products supplied by MEP Films and world-leading innovators, 3M™. Excellent results with fast paybacks are achievable, depending on your requirements.

A scanning objective lens that magnifies 4x is the shortest objective and is useful for getting a general overview of a slide. A low-power objective lens magnifies 10x, but remember that it is coupled with an eyepiece lens, so the total magnification is 10x times the power of the eyepiece lens. A high-power objective lens magnifies 40x, with total magnification 400x if the eyepiece lens is 10x power, and it is ideal for observing very fine detail, such as nerve cells in the retina or the striations in skeletal muscle.

This radiation is responsible for generating photochemical smog and is the single most destructive UV band on fabrics and plastics – resulting in degradation and colour loss. Half of UVA light penetrates glass.

Before you use a microscope, it helps to know what all the different parts are for. Many people believe that the objective lenses are the most important components of a microscope. Basically, without them, your microscope experience would be very disappointing.

Most microscopes come with at least three objective lenses, which provide the majority of image enhancement. The function of objective lenses is to magnify objects enough for you to see them in great detail.

» Being shaded from the sun’s direct light rays provides only partial protection from UV radiation exposure because of high levels of diffuse or reflected UV radiation.

Armmicroscope function

Every microscope has an eyepiece lens, which is the lens at the top that you look through. A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. The eyepiece lens is usually 10x or 15x power (i.e., what you look at appears to be 10 times or 15 times closer than it actually is). A rotating nosepiece or turret holds two or more objective lenses, and you can easily switch between them to change power. A microscope's stage is the flat platform that holds the slides. Some microscopes also have a condenser lens, which focuses the light onto the object, and a diaphragm or iris, which is a revolving disk with holes of varying sizes. The iris is used to vary the intensity and size of the light that is streamed upward into the slide.

Although UVB radiation has some beneficial effects, including the production of Vitamin D in humans, the harmful effects can be serious, causing sunburn, melanoma and other skin cancers, and damage to the eye tissue. UVB light is reflected by glass.

The longest objective lens is an oil immersion objective lens, which magnifies 100x. The total magnification is 1000x if the eyepiece lens is 10x power. The oil immersion objective lens is used for examining the detail of individual cells, such as red blood cells. This lens requires a special oil to form a link between the edge of the objective and the cover slip. Before you use an oil immersion objective lens, ensure the specimen is in focus under the high-power objective lens. After you remove the high-power objective, put a tiny amount of oil onto the cover slip above the specimen, and then move the oil immersion lens into position.
