2. What are
broadband IR sources NOT useful for?
- General space heaters as they are far too small.
- Long term Battery operation. An IR-12K will run off a set of
four AA batteries for about an hour.
- Communication systems. Most parts can only be pulsed at less
than 1Hz and even the IR-50 can only be pulsed at 100Hz. This not suitable for
most communication systems. Consider instead 850nm to 900nm LEDs which are a
lot cheaper, a lot faster and a lot more energy efficient for the
- Near IR illumination. Cheap IR cameras work at around 800nm
to 900nm. The output of broadband IR sources is small at these wavelengths so
again, IR LEDs operating at these wavelengths should be used.
- Mounting on or near people, animals or flamable objects.
These IR sources are exactly like miniture bar fires and reach the same high
temperatures. They can very easily burn people and set fire to objects that get
near to or touch them. It is therefore very important that the users ensures
this can't occur.
