NIST-TRACEABLE CALIBRATION INCLUDED

Traceable calibration provides the ability to trace the readings of laser output measurements to known international measurement standards determined by the National Institute of Standards and Technology (NIST). This ensures that the measurements taken by the instruments are reliable and accurate.

Benefits include:

  • Make valid comparisons of measurements taken by other instruments inside and outside your organization and over time
  • Comply with regulations or conform to industry standards
  • Avoid costly measurement mistakes in your operations
  • Improve customer confidence in your laser systems
  • Ensure laboratory experiment validity
  • Demonstrate measurement accuracy easily with the calibration certificate we provide
 

Handle high repetition rates with the MT absorber

Designed for pulsed lasers with high repetition rates, the MT absorber features an improved temporal response to accurately measure pulse-to-pulse energy at high repetition rates up to 10 kHz.

Customers enjoy:

  • Measure all pulses at high repetition rates
  • Low risk of damaging the equipment
  • Suitable for a wide range of laser wavelengths

FAQ

  • What is this product used for?

    The QE4SP-S-MT-D0 is used to measure small laser pulse energies with Gentec-EO’s smallest pyroelectric energy detector. It is suited for compact optical setups, oscilloscope-based measurements, and high-repetition-rate pulse monitoring where a very small detector head is needed.

  • What are its key specifications?

    Key QE4SP-S-MT-D0 specifications include MT absorber, maximum measurable energy of 0.043 J, noise equivalent energy of 1 µJ, pulse measurement capability up to 6,000 Hz, BNC-mounted operation for direct oscilloscope reading, and custom-built configuration options for application-specific requirements.

  • How do I choose this model vs another?

    Choose this model when space is limited or when you need a very small high-repetition pyroelectric detector. Choose QE12, QE25, or QE50 models if you need a larger aperture, higher measurable energy, QED attenuation, or standard modular stand-mounted QE configurations.

  • What accessories/options are compatible?

    Compatible accessories/options include DB15-BNC adaptor for QE series, NAN-915 protective carrying case, compatible Gentec-EO displays and PC interfaces, absorption curves, PC-Gentec-EO software, and custom-built configuration options from Gentec-EO.

  • What should I know before buying?

    Before buying the QE4SP-S-MT-D0, confirm that your pulse energy is within the 0.043 J range and that the small detector format fits your beam size and optical setup. Also verify wavelength, repetition rate, oscilloscope/interface requirements, and whether a custom configuration is needed.
