L40(150)A-IPL sensor for gel measurements. This sensor is specially designed for measuring pulses from gel coupled IPL dermatological sources. It allows a widely divergent gel coupled beam to go through the unit without back reflections. The sensor has a 22x22mm aperture that can also sample larger sized sources and can measure energy from 100mJ to 2000J. It has the high damage threshold LP2 absorber and covers the spectral range from 0.5 to 1.3µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.
