IR-Emitters
Variably pulsable up to 100 Hz at temperatures of up to 750°C.
In the following, thermal emitters are referred to as IR emitters (as opposed to diode lasers).
LASER COMPONENTS’ range of products includes emitters produced in house. All IR emitters are delivered in a TO housing.
IR emitters often compete among users with special, inexpensive micro incandescent lamps. These lamps often feature a suitable level of radiation at wavelengths of up to approximately 4.5 µm; however at larger wavelengths, the use of IR emitters is mandatory.
Although, it may also be sensible to use special IR emitters below 4.5 µm:
For one, IR emitters are mechanically robust; for another, some models are particularly suitable for electric pulsing (some up to 100 Hz).
Micro incandescent lamps will see a tendency toward a decline in production because use of alternative technologies in control panels and displays will dominate this area more and more.
LASER COMPONENTS’s diamond-like sources (DLS) are MEMS structures; more specifically, they are micromechanically-structured hot plates. A carbon-based nanocomposite (amorphous diamond) is deposited as a resistance material on a silicon membrane. The material has two main features: a very low temperature coefficient of the resistance and a rate of emission of 80%. Contact us today for more information!
Special Advantages:
- Due to the short thermal time constant, modulation depths of approximately 25% and 10% can be achieved at modulation frequencies of 100 Hz and 1000 Hz, respectively.
- Due to constant resistance, a spike in current cannot be observed at start-up.
- The emitter is stable in shape and position.
- At a maximum temperature of 750°C (10 Hz, duty cycle: 50%), a life expectancy of 30,000 hours can be achieved; at 600°C, 250,000 hours can be achieved.
Further Informatio
The DLS series succeeded the previous Intex emitters. One major improvement is the significantly increased reliability that can be traced back to a tighter process control and homogeneous membranes.
The actual active material is referred to as nano-amorphous carbon (NAC) and is a member of the diamond-like materials. NAC has two structural networks: hydrogen-containing carbon and a network that consists of silicon oxides. Both structures stabilize each other and prevent crystallization.
