Overview
Real time measurement of laser power meter
Product Details
1、 Summary:
The conventional power meter is a thermocouple type, and its measurement time is generally 3-5 seconds; For some situations that require rapid measurement, this type of power meter cannot meet the requirements. The PowerMax Pro series adopts thin-film power measurement technology, which reduces the response time to 10us, enabling real-time measurement of changes in laser power and analysis of modulation curves of modulated lasers.
2、 Product physical picture:
3、 Characteristics:
>Provide two communication interfaces: USB and RS232
>The time required to measure power is less than 10us
>Capable of measuring the pulse shape of pulsed lasers
>An average power testing range of up to 150W
>30x30mm ultra large effective detection surface
