Laser energy sensor handles broad spectrum

The PE50BF-DIF pyroelectric detector is said to have a wider spectral range and higher damage thresholds than any energy sensor of its type. Its broadband absorber collects measurements from 193 nm to 3 µm with a single diffuser, thus handling a broad range of measurements.

The 35-mm aperture sensor works with most low/high-energy, short/long-pulsed lasers measuring repetition rates to 120 Hz with pulse widths to 5 ms. Damage thresholds range from 4 J/cm2 at wavelengths 2
