SUMMARY

This discussion focuses on methods to visualize infrared (IR) and ultraviolet (UV) waves. Infrared can be observed using an infrared camera, which some smartphones possess. For ultraviolet, specialized UV cameras are necessary, as standard digital cameras cannot capture UV light due to lens absorption. The conversation also highlights the dangers of UV exposure, particularly to skin and eyes, and suggests DIY methods for IR photography by modifying existing cameras.

PREREQUISITES
  • Understanding of infrared camera technology
  • Knowledge of ultraviolet light properties and safety
  • Familiarity with digital camera modifications
  • Basic principles of light and optics
NEXT STEPS
  • Research infrared camera options and smartphone capabilities
  • Explore UV camera technologies and their applications
  • Learn about DIY modifications for digital cameras to capture IR photography
  • Investigate the effects of UV exposure on human health and safety measures
USEFUL FOR

Individuals interested in photography, physics enthusiasts, and anyone looking to safely explore the properties of infrared and ultraviolet light.

Hello physics community,

Im new here, and this is my first post.

Im searching the internet, looking for a way to see the infrared waves and ultraviolet waves.
I know I have to use a secondary way to look at these waves.

Its really a great help, if you can tell me few simple equipments , which I can make myself at home. And also the scientific equipments that I can use for this.

I know I sound primary, but I am just trying to expand my viewing range and knowledge.

thanks a lot.

Infrared can be viewed with an infrared camera. some handphones have this functionality. ultraviolet rays can be seen using

UV light is dangerous and can cause skin cancer so keep your distance...

Not only is UV damaging to the skin, it is not very healthy to have UV strike the eyes.

This article discusses the damage that UV exposure can cause to one's eyes and vision:

Nonetheless, it is possible to survive the experience of walking in the garden in full sunlight - with plenty enough UV radiation for an appropriate camera / sensor to detect it. Many insects have UV sensitive vision and many flowers have UV reflective patterns to show where the nectaries are. Humans do not see these.
A normal digital camera sensor is sensitive to IR and people used to remove the IR filter in older cameras and do IR photography (btw you can also get IR film). However, normal lens glass absorbs UV and you can't do the same trick with UV. You'd have to Google UV camera.
 
thanks everyone, appreciate it.

Humans can actually see UV light, but you have to lack a lens to do so.

The fact that there are insects with UV vision could be due to the different optics (no lens of any thickness in a multiple eye). This would reduce the absorption of UV,, which would mean they could use the same light sensing chemistry as mammals (humans).
 
Try pointing a TV remote control at the video camera on your mobile phone. Sometimes you can see the IR LEDs flashing or at least light up when buttons are pressed.
 
Try YouTube for UV. There is at least one on there by someone that had a canon 600D modified to a full spectrum by removing an internal filter.

Not cheap option.

I track a 248 nm UV laser path by using a simple business card. It has a coating that causes it to fluoresce when the light impinges on it.
