Product Description

The Infrared sensor adds another dimension to heat loss and energy transfer experiments. 

 


2-minute - Earthquake Rescue


40-sec - Infrared sensor - Leslie's cube

Multiple ranges to cover a wide range of energy sources. Includes silica glass filter to block mid and far infrared making the sensor selective for low and high temperature sources. 

 

Teaching applications:
  • Herschel’s discovery of infrared experiment
  • Study inverse square to verify that heat radiation from source is inversely proportional to the square of its distance
  • Infrared emission from a Leslie’s cube
  • Efficiency of insulation such as clothing or building materials
  • Infrared in the environment
  • Explaining infrared thermography

Extension and advanced ideas:
  • Black body studies (radiance range)
  • Investigating Stefan-Boltzmann’s radiation law using a tungsten filament lamp
  • Modelling infrared discovery of people in disaster zones
  • Heat distribution along a heated metal rod
  • Illustration of non-contact thermometry

The detector window is made from KBr (potassium bromide), which is transparent to energy sources radiating in the wavelength region from 0.23 microns (230 nm) to 40 microns (40,000 nm) i.e. ultraviolet through to the far infrared portion of the spectrum. KBr (potassium bromide) is hygroscopic so store the sensor in dry conditions.

Measurements can be recorded at three levels using either a Radiance (the intensity of the emitted thermal energy of the source) or Irradiance (the intensity of the incident thermal radiation on the Sensor) range.

The silica glass detachable filter allows visible and near infrared to pass i.e. 0.15 to 4 microns but will block out mid and far infrared.

Wavelength region Without filter 0.23 - 40 microns With filter 0.23 - 4 microns

Infrared face imaging (Biology (11-14) ebook)
This is a fun way of introducing the the concept of medical imaging and non contact thermometers. Make your own thermal selfies. 

Hot Stuff (Biology (14-18) eBook)
A fun way of introducing medical imaging and infra red non contact thermometers. Students create a colour key and a false colour heat map of their face. 

Finger Prints (Biology (14-18) eBook)
infra red is an important tool in modern biology and medical science. This activity introduces the infra red sensor by looking for heat traces after touching surfaces. Many animals also detect infra red to determine size and position of prey. Can be used to illustrate the advantage this has for a predator.

Bodies in the Rubble (Biology (14-18) eBook)
In the early stages of a natural disaster there is a lot of effort placed into finding survivors who have been buried in the rubble of collapsed buildings. This is an activity to model how infra red technology is used to find survivors. 

Temperature vs. Infra red (Biology (14-18) eBook)
Non contact thermometers are frequently used by medical personnel. This activity shows how the link between temperature and infra red is made. Students can make their own thermometer from the infra red sensor. 

 

Leslie's cube (Physics (14-18) : Electricity & Heat eBook)
The Scottish scientist Leslie studied how the loss of energy from a surface was influenced by the texture and colour of the surface. Anecdotal evidence suggests that dark clothing makes you feel hotter in summer. Is there any supportive science for this belief? 

Temperature Vs Infra red (Physics (14-18) : Electricity & Heat eBook)
how does the infra red emitted from a hot body relate to the temperature? can you make a non contact thermometer? 

What type of surface absorbs radiant energy? (Physics (14-18) : Electricity & Heat eBook)
This investigation encourages the student to think about how surfaces absorb and re-radiate heat energy. Many students hold the belief that a white surface will absorb and radiate the least heat. In the investigation, this assumption is challenged and tested. 

Residual heat: Thermal imaging. (Physics (14-18) : Electricity & Heat eBook)
Infrared energy is emitted from any object that contains heat. In this investigation we build on the experiences of many students with a non contact thermometer and pictures of modern weapons attacks to think about how infrared imaging works.

Survivors In the rubble (Physics (14-18) : Electricity & Heat eBook)
This experiment is designed to illustrate the principles of the devices used by the emergency services. The device will not show the outline of the hidden object, perhaps with a carefully drawn grid and snapshot measurement a “thermal contour” map could be created? 

Hot Stuff: Thermal map of your face (Physics (14-18) : Electricity & Heat eBook)
This is quite a fun way of introducing the Infrared sensor and hidden part of the spectrum to the students. Create your own thermal selfie. 

Stefan - Boltzmann law. (Physics (14-18) : Electricity & Heat eBook)
The experiment illustrates the Stefan - Boltzmann law. It does not give a value for the Boltzmann constant. A simple tungsten filament automotive lamp is used as the source of thermal radiation. The investigation tests if the radiation is really to the 4th power of temperature.

Infra red in the spectrum (Physics (14-18) : Light, Sound & Pressure eBook)
Use a light sensor and infra red sensor to reveal the wider spectrum. 

 

Hot stuff mapping (Science in Sport (11-18) eBook)
Controlling heat in sport is important, Thermal imaging can help to design heat loss into clothing or to reduce heat loss as required. A demonstration model to show how thermal imaging works. 

The right clothes for the right sport (Science in Sport (11-18) eBook)
The Scottish scientist Leslie studied how the loss of energy from a surface was influenced by the texture and colour of the surface. Anecdotal evidence suggests that dark clothing makes you feel hotter in summer because it absorbed the suns’ heat . But is sports clothing more about function or etiquette?

Infra red and sunlight (Science in Sport (11-18) eBook)
A little light relief. Why can they light the olympic torch from sunlight on mount olympus? 

 

Should i wear light coloured clothes in the summer to keep me cool? (Science At Work (11-16) eBook)
A study into colour and heat gain and loss. An old argument studied, white cotton keeps me cool in the summer, but why does black clothing not keep me hot in the winter? 

How does infra red and temperature link? (Science At Work (11-16) eBook)
make a non contact thermometer from an infra red sensor 

Finger prints (persistence of heat images) (Science At Work (11-16) eBook)
Find out where your fingers have been using an infra red sensor.

Hot Stuff (thermal mapping of your face) (Science At Work (11-16) eBook)
This is quite a fun way of introducing the Infrared sensor and hidden part of the spectrum to the students. Most students will not have experienced how infrared works, they may have seen the result of infrared imaging. Make your own infra red selfie 

Bodies in rubble (infra red to find survivors) (Science At Work (11-16) eBook)
This experiment is designed to illustrate the principles of the devices used by the emergency services. The device will not show the outline of the hidden object, perhaps with a carefully drawn grid and snapshot measurement a “thermal contour” map could be constructed.
