Infrared examples

As well as the acute risks posed by overheating, the chronic effects of infrared light on the eyes (damage to lenses and retina) are good reason to wear appropriate personal protective equipment when working with infrared radiation.

These simple microscope experiments can provide valuable insights into the microscopic world and enhance your understanding of biology, chemistry, and environmental science concepts. Experimenting with a simple microscope is a fun and educational way to explore the hidden details of the world around you.

First of all, welding spectacles and infrared safety spectacles are subject to two different safety standards: while welding spectacles are designed specifically for welding applications and the respective output from the welding machine in accordance with EN 169, infrared safety spectacles are designed in accordance with EN 171; this standard intends for the eye protection to be selected according to the average temperature of the radiating heat source.

Infrared radiation, or thermal radiation, was discovered in the year 1800 by Friedrich Wilhelm (William) Herschel, musician and astronomer. Everyday sources of infrared radiation include:

Simple microscopes are versatile tools that can be used for various experiments and observations. Here are some simple microscope experiments you can perform:

Infrared wavelength range in nm

The magnification of a simple microscope is determined by the focal length of the lens and the distance between the lens and the object being observed. The magnification formula for a simple microscope is:

Depending on its intensity, proximity and the duration of exposure, infrared radiation can be harmful to the eyes as well as to the skin. The eyes generally react much sooner and are much more sensitive than the skin to the effects of IR radiation, which can be harmful from a certain degree of intensity and exposure. The heat can in fact be beneficial to skin to a certain extent: infrared heat in the form of infrared lamps is used for medical purposes such as treating pain, circulation problems, stiff joints, inflammation etc. However, excessive heat can also cause heat cramps, heat exhaustion, heatstroke and burns.

In the case of a simple microscope, the final image size is the size of the object as seen through the lens, and the actual object size is the size of the object without magnification.

The main difference between a simple microscope and a compound microscope lies in their optical systems and magnification capabilities.

In professional settings, employees working in glass production and the processing of metals or plastics are among those exposed to the potentially harmful effects of infrared radiation, which is invisible to the naked eye. This article will set out the dangers posed by infrared, list the areas in which IR radiation is found and provide clarification on effective measures to tackle the problem.

If you operate in areas with particularly high levels of infrared radiation – right in front of the iron-melting furnace, for instance – heat protection clothing and special heat protection are indispensable.

A pair of uvex IR-ex spectacles can provide you with optimum protection against the effects of infrared in your workplace. To determine which spectacles have the correct level of protection, establish the average temperature of the source of radiation – i.e. the burning object (such radiation measurements are performed as part of the workplace risk assessment in larger companies). The table provided sets out the official levels of protection of the relevant EN 171 standard and the level of protection that uvex infrared spectacles offer:

While simple microscopes are relatively straightforward in design compared to compound microscopes, which have more complex optical systems, they are essential tools for magnifying small objects or details in various applications. The basic parts listed above enable users to effectively observe and study specimens with enhanced visual clarity.

Comparing the two standards and the protective effect mentioned therein of welding safety spectacles and infrared safety spectacles, it quickly becomes clear that IR spectacles are capable of absorbing five to ten times more radiation within the 700 to 2,700 nm spectrum than welding spectacles – while still allowing just as much visual radiation through. Our professional uvex IR-ex infrared safety spectacles therefore provide effective protection when working with both types of radiation, meet both standards (EN 169 and EN 171) and are way ahead of welding spectacles when it comes to the protection that they offer. And, because our IR-ex spectacles also provide protection from UV radiation up to 400 nanometres, the requirements of EN 170 for UV filters are also met. Our IR-ex tint therefore offers multiple types of protection for virtually all hazards posed by optical radiation. This multi-certification allows our infrared spectacles to be used for protection when welding and from solar radiation as well. Conversely, a pair of welding safety spectacles does not provide sufficient protection against infrared!

Our infrared light spectacles also meet the requirements of U.S. standard ANSI/ISEA Z87.1 and Japanese standard JIS T8141. This multi-certification allows our infrared spectacles to be used for protection when welding and from solar radiation as well. Conversely, a pair of welding safety spectacles does not provide sufficient protection against infrared!

Infrared is radiation with a wavelength between 780 nanometres and one millimetre on the electromagnetic spectrum. This IR radiation cannot be perceived by the naked eye, even if the heat emitted by the radiation can be felt. Particular caution is therefore required when dealing with extremely warm and prolonged radiation. Infrared light is divided into three types depending on the wavelength: IR-A, IR-B and IR-C. The longer the waves of the IR radiation, the less able they are to penetrate fabric or dermal layers. At 780 nm to 1,400 nm, the comparatively short-wave IR-A radiation is therefore the most harmful type in terms of human health (greatest degree of penetration). UV light is also invisible, but its wavelength spectrum is below 400 nm and it therefore has a shorter wavelength than radiation within the visible range of the spectrum.

When it comes to the long-term dangers posed by infrared radiation, the key question is how to provide employees with effective, reliable protection to keep them healthy while they work.

In the infrared light risk assessment for your workplace (for eyes and skin), your distance from the source of radiation and the amount of time spent in front of the radiation source are also relevant in determining the strength of your IR radiation exposure.

Infrared wavelength

All filters of the infrared safety spectacles and of other PPE in this range must meet the transmission requirements of EN 171 and are divided into defined levels of protection accordingly. Standard 166 for general personal eye protection stipulates further requirements for infrared safety spectacles. You can find illustrations and other explanations of these specifications and the applicable standards for safety spectacles on our website.

Whether you work right in front of a furnace in a foundry or a certain distance away, appropriate eye and face protection – plus where necessary the right heat protection clothing – are essential for you to be able to work safely.

Yes, a magnifying glass is indeed an example of a simple microscope. It consists of a single convex lens that is used to magnify small objects or details when they are held close to the lens. Magnifying glasses are commonly used for tasks such as reading small print, examining objects, and conducting simple observations of various materials. They operate on the same principle as other types of simple microscopes, providing moderate levels of magnification suitable for everyday use.

Aside from the aforementioned situations in people’s personal lives, there are many industrial settings in which infrared radiation is used in a variety of ways. Typical examples include:

A simple microscope is a fundamental optical device comprised of a single lens that magnifies objects when they are placed close to the lens. This lens, typically convex in shape, bends light rays passing through it, allowing for the enlargement of the object's image. Simple microscopes are commonly used for various applications such as reading small text, examining specimens, or inspecting details in crafts and artwork. They are portable, easy to use, and provide moderate levels of magnification suitable for everyday tasks requiring enhanced visual clarity.
