Infrared LEDs, with peak wavelengths in the IR-A spectral range from 700 to 1400nm, are utilized in a wide variety of applications from surveillance/safety, industrial machine vision & sensing, medical health monitoring and biometrics, many automotive, home and entertainment devices.
Gigahertz-Optik’s hand-held X1-1 radiometer with RW-3704-4 detector measures irradiance from 0.001 µW/cm² to 10 W/cm² at 850nm.
Where extremely low sensitivity is required the 16 bit P-9710 radiometer with 5fA offset can be used.
The cosine corrected RW-3704-4 detector covers the spectral range from 800 to 1100nm. The K-RW3704-SD spectral irradiance calibration is recommended where user menu selectable calibration points are provided every 10nm to adjust the calibration to an LED peak wavelength.
The 4-channel X1-1 meter features, CW, dose, run/stop, offset, auto/manual range and peak hold modes of operation. Other standard features include USB interface, backlit LCD and it is compatible with all other Gigahertz-Optik single and multi-sensor (up to 4) light detector heads.
Optional S-X1 software supports full computer control of all meter functions and data processing.
The four-channel X1-1 radiometer can simultaneously process and display readings for up to four different Gigahertz-Optik detector heads using the X1-Z03 detector mux box.
