Product Description

Excellent measurement accuracy, wide energy measurement range
WIde wavelength measurement range
various effective detection areas available

LBTEK pyroelectric laser energy meters are available with black coating, metal coating, and ceramic coating. Among them, the black and ceramic coatings operate within a wavelength range of 190 nm to 25 μm, while the metal coating functions from 190 nm to 2.5 μm. The LBTEK pyroelectric laser energy meters provide a flat response across their respective wavelength ranges. Additionally, they feature a wide measurement energy range, capable of detecting pulse sources with energies from 1 μJ to 15 J. They also come with a broad selection of detection areas, with maximum incident spot diameters ranging from 4 mm to 45 mm. Users can choose the most suitable product based on specific requirements.

Standard Pyroelectric Laser Energy Meter

For pulsed laser measurement
Black coating with flat response over a wide wavelength range
Various effective detection area available

The LBTEK standard pyroelectric laser energy meter is used for measuring pulsed lasers. The pyroelectric sensor converts the energy of light pulses into voltage pulses and is not suitable for continuous laser measurement. Due to its black coating, which exhibits a flat absorption curve within the 190 nm–25 μm wavelength range, it is particularly well-suited for low-power, wavelength-independent energy measurements. Among them, the LBPEM20/45-HP offers higher average power density. Additionally, the energy meter can be directly connected to an oscilloscope with a 1 MΩ input resistance or an LBPEM710 meter via a BNC connector. To accommodate higher repetition rates when connected to an oscilloscope, the load resistance can be reduced. The LBTEK general-purpose pyroelectric laser energy meter provides optional effective detection areas of 4 mm, 8 mm, 11 mm, 20 mm, 21 mm, 34 mm, and 45 mm. The energy meter includes a 1.5 m-long connecting cable with BNC and E connectors on either end. Note: The energy meter includes a mounting rod but does not come with a base.

High-Energy Pyroelectric Laser Energy Meter

Suitable for measuring high-energy pulsed lasers up to 15 J
Ceramic coating with high damage threshold, suitable for high energy density (up to 1 J/cm²) lasers
Available with optional 20 mm or 45 mm effective detection area

The LBTEK High-Energy Pyroelectric Laser Energy Meter is designed for measuring high-energy pulsed lasers, making it highly suitable for excimer lasers, CO₂-TEA lasers, and ND:YAG lasers. The pyroelectric sensor converts the energy of light pulses into voltage pulses and is not suitable for continuous laser measurements. The ceramic coating of the high-energy pyroelectric laser energy meter features a flat absorption curve within the 190 nm–25 μm wavelength range. Among them, the LBPEM20-K energy meter can measure high-energy laser pulses up to 3 J, while the LBPEM45-K can measure high-energy laser pulses up to 15 J. Additionally, the meter can be directly connected to an oscilloscope with a 1 MΩ input resistance or the LBPEM710 meter via a BNC connector. To accommodate higher repetition rates when connected to an oscilloscope, the load resistance can be reduced. Our product offers optional effective detection areas of 20 mm and 45 mm. The energy meter includes a 1.5 m-long connecting cable with BNC and E connectors on each end. Note: The energy meter includes a mounting rod but does not come with a base for sale.
