Maximize year-end capital equipment dollars.


For a limited time, when you buy any industry-leading, low noise QCL LAB Instrument, receive a PTC10K-CH Precision Temperature Controller for free. 

The patented technology of the QCL LAB quantum cascade laser driver reduces jitter, minimizes noise for narrow linewidth and delivers exceptional current stability for repeatable scans. 

The mK temperature stability of the PTC controller supports highly stable wavelength output.


QCL LAB features include:
  • Output currents of 500 mA, 1 A, 1.5 A, 2 A
  • Low noise: <0.4 μA RMS up to 100 kHz (QCL500, typical)
  • Compliance voltage is adjustable, 10 to 20 V
  • Analog modulation up to 2-3 MHz
  • Constant Current Mode operation
  • Touchscreen with intuitive user interface
  • CE compliant, compatible with CDRH laser regulations
  • Feature-rich for research projects
    • USB and Ethernet interfaces with software included
    • Auto voltage/current scan function
    • Data collection using a computer or USB flash drive
    • Field upgradeable firmware
    • Sophisticated error handling
    • Save and recall functions for specific set ups
  • Rack mountable: 2 U height and ½ rack width
  • Safety features protect your QCL investment
    • Adjustable soft-clamp current limit, with Brick-Wall Never-Exceed circuitry
    • Password protection available to lock out a selectable control set
    • Keyswitch, active, and passive interlocks
    • Brown-out & overvoltage protection
    • Power supply overcurrent protection
    • Driver over-temperature protection circuit
    • Relay shorts output when current is disabled
    • AC input and patented power supply filtering
    • 2 second turn-on delay — adjustable
    • 1.5 msec current ramp


PTC10K-CH features include:
  • Drives up to ±2.5, ±5.0, or ±10.0 A of linear bipolar TEC or heater current
  • With a booster unit, drives up to ±20.0 A
  • Single supply operation: 5 to 30 VDC
  • Small package: 3.0” x 3.2” x 1.1”
  • Use a wide variety of temperature sensors
  • Remote Output and Setpoint controls
