LBTEK pyroelectric laser energy meters offer three optional coatings: black, metal, and ceramic. The black and ceramic coatings operate over a wavelength range of 190 nm to 25 μm, while the metal coating covers 190 nm to 2.5 μm. Within these wavelength ranges, the energy meters provide a flat response. They feature a wide energy measurement range, capable of detecting pulse energies from 1 μJ to 15 J. Additionally, they offer a broad selection of detector areas, with maximum incident beam diameters ranging from 4 mm to 45 mm.
The fast-response pyroelectric laser energy meter is designed for measuring pulsed lasers with repetition rates up to 2.5 kHz. The pyroelectric sensor converts light pulse energy into voltage pulses and is not suitable for continuous-wave laser measurement. The PEMxx-HiRep model features a black coating that provides a flat response from 190 nm to 25 μm and supports measurement repetition rates up to 750 Hz. The PEMxx-HiRep-UV model uses a metal coating with a flat response from 190 nm to 2.5 μm and supports repetition rates up to 2.5 kHz, depending on the effective detector size. The energy meter can be connected directly to an oscilloscope with a 1 MΩ input impedance or to the LBPEM710 meter via a BNC connector. Effective detector areas of 12 mm and 24 mm are available. Each energy meter comes with a 1.5 m connection cable with BNC and E connectors at each end.
Note: The energy meter is supplied with a mounting post but does not include a base.
