K11908-010K

Two-color detector K11908-010K Two InGaAs PIN PD with different spectral response are arranged one above the other to cover a broad wavelength range The K11908-010K incorporates an InGaAs PIN photodiode (cutoff wavelength: λc=1.7 μm) mounted over a long wavelength type InGaAs PIN photodiode (λc=2.55 μm), along the same optical axis. The spectral response covered from 0.9 μm to 2.55 μm as wide range and delivers low noise. Features InGaAs (λc=1.7 μm) mounted over InGaAs (λc=2.55 μm) along the same optical axis Wide spectral response range: 0.9 to 2.55 μm Low noise, low dark current Applications Radiation thermometer Spectroscopy Optical measurement equipment Structure Parameter Window material Package Photosensitive area Symbol - - Condition InGaAs (λc=1.7 μm) InGaAs (λc=2.55 μm) Specification Borosilicate glass 4-pin TO-5 2.4 × 2.4 φ1.0 Unit - mm Absolute maximum ratings Parameter Reverse voltage Operating temperature Storage temperature Symbol VR max Topr Tstg Condition InGaAs (λc=1.7 μm), Ta=25 °C InGaAs (λc=2.55 μm), Ta=25 °C Value 2 1 -40 to +70 -55 to +85 Unit V °C °C Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality.
