– selective photodiodes

7h used in measurement and control of all parts of the spectrum
7h in blue and ultraviolet for water purification, burner control,
hh ozone monitoring and laser detectors
7h enables daylight sensors in the visible range
Photosensivity (A / W) 7h lane departure warning systems and safety engineering systems
hh in the infrared
Wavelength (nm) Comparision of Epigap‘s selective PD vs. BPX 65

Advantages

7h high spectral sensitivity across different wavelength ranges
7h integrated optical filters, no additional filters necessary
7h very good signal-to-noise-ratio
7h signal / noise - ratio low dark currents
7h high linearity of photocurrent
7h high temperature stability and low degradation of sensitivity
