Terahertz laser power and beam profiling measurement is not a trivial task. But as anyone using or developing THz lasers knows, it is crucial to obtain accurate measurements of your laser. Ophir offers a few choices, depending on what aspect of your laser you need to measure. Read these posts for more about Terahertz measurement.

RM9-THz with Chopper
P/N 7Y70678
ApertureØ8mm

Spectral Range0.1-30THz

Power Range100nW-100mW

Energy RangeN.A.

Backscattered PowerN.A.

DimensionsØ62 W x 21 D (mm)
The RM9-THz radiometer system is a sensor and optical beam chopper combination for measuring the power of very low level CW or quasi CW light sources. This sensor was specially designed for work in the terahertz range. The RM9-THz sensor has a pyroelectric element to measure a wide dynamic range of radiation, from 100nW to 100mW. It has an 8mm aperture and covers the spectral range from 0.1THz to 30THz. The system comes with the RMC1 chopper that is placed between the source and the RM9 sensor. The chopper should be mounted with the side marked "THIS SIDE TOWARD SENSOR" facing the sensor.
