ILX LIGHTWAVE LDT-5525B 24W Thermoelectric Temperature Controller

The ILX Lightwave LDT-5525B is a precision; microprocessor based thermoelectric (TE) temperature controllers that deliver a low noise, bipolar constant current output of up to 4 Amps and 24W of heating or cooling power. These instruments close a precision temperature control loop through a variety of temperature sensors and display temperature from -99° C to 199° C or sensor resistance. The temperature controller topology, paired with a hybrid smart-integrator control loop result in fast settling times with a temperature stability of 0.004 C which is ideal for laser diode or optoelectronic component testing requiring stable wavelength and optical power.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
