STANFORD RESEARCH SYSTEMS LDC502 2000 mA Laser Diode Controller

The SRS LDC502 Laser Diode Controller is an ideal instrument for controlling the current and temperature of your laser diodes. It has the performance and features you expect from instruments costing twice as much. The LDC502 has up to 2 A of output current with less than 3.5 µA of rms noise. The SRS LDC502 is a 36 W high-precision temperature controller with standard computer interfaces, including Ethernet. It has multiple laser diode protection features, including slow start turn-on, adjustable current limits, and adjustable compliance voltage. Specifications. Current Source Range: 0 to 2 A, 0 to 1 A. Setpoint resolution: 0.1 mA. Accuracy: ±0.02 % of full scale. Output impedance: >1 M-ohm (DC). Thermal Stability: <10 ppm/°C.

*This is a Web introductory price for one calibration of the STANFORD RESEARCH SYSTEMS LDC502. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Absolute Wavelength Accuracy
Absolute Wavelength Accuracy is the maximum difference between the actual wavelength and the displayed wavelength of the Optical Source. Wavelength is defined as wavelength in vacuum.

Decibel (dB)
A unit of measurement of optical power which indicates relative power. A -10 dB means a reduction in power by 10 times, -20 dB means another 10 times or 100 times overall, -30 means another 10 times or 1000 times overall and so on.

Nanometer (nm)
A unit of measure used to measure wavelength of light, meaning one one-billionth of a meter

Relative Intensity Noise (RIN)
Relative intensity noise (RIN), describes the instability in the power level of a laser. The noise term is important to describe lasers used in fiber-optic communication and LIDAR remote sensing. It is the square of the (spectrally resolved) RMS optical power amplitude divided by the measurement bandwidth and the square of the average optical power, expressed in dB/Hz.

Total Return loss
In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. RL = - 10log10 (Preflected/Preference)
