Arduino Laser Infrared Thermometer : 7 Steps (with ...

A quick noncontact check with an infrared thermometer can let you know what is happening with the temperature of a machine so you can shut if off before it causes permanent damage. Infrared radiation is just another type of radiation that exists on the electromagnetic spectrum. We cannot see it but if you were to place your hand near a something hot like a stove top, then you would be feeling ...

The Correct Material for Infrared (IR) Applications

The index of refraction ranges from approximately 2 for visible materials and 4 for IR materials. In many cases, index of refraction and density share a positive correlation, meaning IR materials can be heavier than visible materials; however, a higher index of refraction also implies diffractionlimited performance can be achieved with fewer lens elements – reducing overall ...

The Correct Material for Infrared (IR) Applications

For example, consider silicon, which transmits IR but not visible light (Figure 2). Figure 2: Uncoated Silicon Transmission Curve. Index of Refraction. While it is mainly transmission that classifies a material as either an IR or visible material, another important attribute is index of refraction (n d). Index of refraction is the ratio of the speed of light in a vacuum to the speed of light ...

UVIRCut/ Protection :: Schneider Kreuznach

The UVIRcut filters come with our ultralow reflection coating. Protective filters are used to protect a sensor, a lens or a complete measurement system. Sometimes they are mounted as gauge glass. Often it’s just a window, a glass that passes VIS suited with a standard AR coating, as SchneiderKreuznach IFW 007 E series.

If you haven’t had the infrared cut filter removed from your camera sensor, these filters will substantially extend exposure times. How much depends on the strength of the infrared cut filter on your camera. To give you some idea, I tested this using an Olympus EM5 (Mk1) and a 10mm lens. Without an infrared filter, f/ and ISO200 produced a shutter speed of 1/40”. After adding a 720nm ...

Thermal Infrared Imaging for LongRange Surveillance ...

For visible light, glass lenses are typically used to focus light on a camera sensor, however glass is not transparent to thermal radiation. Instead, thermal lenses are constructed from a special metal called Germanium (Ge). This is a relatively rare element and thus is quite costly, with raw prices often as high as 2000 per kilogram. Depending on the type of sensor, lenses of different ...

Infrared cutoff filter Wikipedia

Infrared cutoff filters, ... A blue filter marginally allows more light in the blue wavelength to pass resulting in a slight shift of the color temperature of the photo to a cooler color. Because of this, the term "IR filters" is commonly used to refer to filters that pass infrared light while completely blocking other wavelengths. However, in some applications the term "IR filter" still can ...
