Keithley 2510/2510-AT/2520 SourceMeter Optical Instrument Optical SMU TEKTRONIX USA

Active temperature control

Prevents temperature fluctuations from shifting the laser diode's primary output wavelength, which can cause signal overlap and crosstalk.

50 W TEC controller

Delivers faster test speeds and a wider temperature setpoint range than lower-power solutions.

Fully digital P-I-D control

Delivers greater temperature stability and can be easily upgraded through a simple firmware change.

Auto-tuning for thermal control loops (2510-AT)

Determines the optimal combination of P, I, and D coefficients without trial and error.

Wide temperature setpoint range (–50°C to +225°C) with high setpoint resolution (±0.001°C) and stability (±0.005°C)

Meets the test requirements for production testing of most cooled optical components and subassemblies.

Compatible with multiple temperature sensor inputs — thermistors, RTDs, and IC sensors

Suited to the sensor types most commonly used in laser diode modules.

AC ohmic measurement

Verifies TEC device integrity.

Four-wire open/short lead detection for thermal feedback elements

Eliminates lead resistance errors and reduces the risk of false failures or equipment damage.
