    RM9-THz with Chopper

    7Y70678
    • Ø8mm
    • 0.1-30THz
    • 100nW-100mW
    • N.A.
    • N.A.
    • Ø62 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.
