Gentec Power Detectors

Gentec-EO power detector heads use proprietary absorber coatings developed in-house, giving industry-leading damage thresholds and broad spectral coverage from 190 nm to 20 µm. Every head ships with NIST-traceable calibration embedded in the smart DB15 connector — no manual entry required when paired with any Gentec display or PC interface.

UP55N SERIES — HIGH-POWER THERMOPILE, 55 mm APERTURE

The most widely used thermopile range for moderate to high-power CW applications. The 55 mm aperture accommodates most collimated or weakly focussed beams. Available in four cooling configurations: convection (40 W), heatsink (100 W), fan-cooled (300 W), and water-cooled (500 W). Spectral range 190 nm – 20 µm; damage threshold up to 45 kW/cm² at 1064 nm. Also measures single-shot energy up to 200 J.

UP16K-QED SERIES — COMPACT 16 mm, VOLUME ABSORBER

Uses Gentec’s QED volume absorber — designed for pulsed beams with high energy density, where tightly focused or high peak-power pulses can damage surface absorbers. Damage threshold: 100 kW/cm² (among the highest on the market). Available from 4 mW to 100 W (water-cooled); energy mode up to 500 J. Also available in the UP52K-QED variant (52 mm aperture) for larger beams.

XLP12 SERIES — LOW-POWER THERMOPILE, 12 mm APERTURE

A low-power thermopile with noise levels approaching a photodiode, giving broadband thermal-detector response and durability at sensitivity levels (0.5 µW NEP) not normally achievable with thermopiles. The XLPF12 variant adds an integrated IR filter to reject background radiation. A volume absorber version (XLP12-VP) is available for ultrashort pulse (ps/fs) lasers at low average power.

• CW LASER POWER MONITORING
  • Continuous power monitoring of CW lasers across UV to far-IR — fibre lasers, CO₂, Nd:YAG, diode, and gas lasers. The UP55N series handles the majority of research and industrial CW measurement requirements up to 500 W.
• HIGH-POWER INDUSTRIAL & FIBRE LASER MEASUREMENT
  • Power measurement of high-power fibre and direct diode lasers in welding, cutting, and additive manufacturing. Water-cooled variants of the UP55N and UP52K-QED handle kilowatt-class powers; the UP16K-QED’s high damage threshold makes it suitable for tightly focussed high-brightness sources.
• PULSED LASER ENERGY MEASUREMENT (THERMOPILE SSE MODE)
  • Single-shot energy measurement from pulsed solid-state and fibre lasers using the UP55N or UP16K-QED in SSE mode. Complements pyroelectric energy detectors (QE series) for slower-repetition-rate or high-energy pulse regimes.
• ULTRASHORT PULSE LASER MEASUREMENT
  • The XLP12-VP volume absorber variant handles ultrashort (ps/fs) laser pulses at low average power without the surface damage risk associated with standard absorber coatings.
• SENSITIVE LOW-POWER CW MEASUREMENT
  • The XLP12 and XLPF12 provide thermopile measurement at sub-microwatt noise levels — suited to attenuated beams, fibre outputs, and any CW application where a photodiode’s wavelength sensitivity limits are a concern.
• LASER SYSTEM ALIGNMENT & OPTIMISATION
  • The MIRO ALTITUDE needle display mode with XNR Anticipation provides faster effective response during laser alignment, making detector heads + MIRO ALTITUDE a productive combination for tuning beam delivery and coupling optics.
