These infrared radiation sources are pulsable thermal emitters with a near black-body emittance. They out-perform traditional IR sources with greater optical power out and more efficiency (less power in). They offer:
- Patented nanotechnology achieves higher efficiency.
- Patented emitter set-up made of a high-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface.
- Lower element temperature of 600°C increases lifetime.
These High Efficiency Emitters boast high stability with minimum drift at constant resistance (Ohm). Their infrared radiation sources are pulsable thermal emitters with a near black-body emittance. Based on the patented nanotechnology and the patented emitter set-up made of a high-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface offer numerous advantages in many applications.”
The emitters are:
- More stable
- Less or no drift
- A lot more power
- 2.5 to 5 times more Sensor gain than Pulsed MEMS IR Sources
- A lot less noise (very important)
- All windows are hermetically sealed (Sapphire, CaF2 and BaF2 windows)
Numerous performance advantages are achieved in many applications:
- SMD emitters are great for many projects where size and power are issues (portable devices and others).
- High power applications (TO39 and TO8 packages) where you can get more power out with the same or less power in.

These thermal infrared emitters can be supplied in a 3×3 mm SMD package (really small). The infrared emitters are small, powerful thermal radiation sources, optimized for portable, battery-operated and mobile sensor applications. The company’s patented nanostructured radiation element technology makes these emitters high efficiency (up to 30% compared to 3 to 5% of MEMS). They offer up to 500% more output power than comparable technologies and can also be produced in larger (TO-39, TO-8) with even more output power. Gases in the ambient air can be analyzed more precisely in lower concentrations and in shorter measuring times. The emitter wide wavelength range works well in a variety of applications including mobile, portable devices and various wearables, for miniaturized gas sensors and handheld spectrometers. Automated low cost SMD assembly makes these sources ideal for high volume applications.

| Basic Series (with Integrated Reflector) | |||||||||
| The Basic Series emitters have an integrated gold plated reflector that directs the radiation emitted from the rear to the front to achieve maximum efficiency and optical output power. The IR emitters are characterized by a very low temperature coefficient of electrical resistance. The electrical control of the infrared sources is easy, as the hot and cold resistances are almost identical. | |||||||||
