Description The MXA-256-X detector is a hybrid focal plane Indium Gallium Arsenide PIN photodiode array with wavelength response ranging from 800 nm to 1700 Multiplexed InGaAs PIN Photodiode Array MXA-256-X 800 - 1700 nm nm. The array has 256 elements IN A NEW LIGHT. configured in a linear orientation with standard pixel height of 0.5 mm. A buffered multiplexer provides individual CMOS amplifiers for each photodiode. The integrating amplifier maintains zero volt bias across each InGaAs photodiode, minimizing dark current and low frequency noise and allowing for longer exposure times with increased sensitivity. A static shift register scanning circuit sequentially selects sample-and-hold integrator output voltages which are proportional to input optical power. On-chip Features correlated double sampling removes • 256 multiplexed elements integrator offsets and further • High resolution (50 micron pitch) suppresses low frequency noise. The • Exposure times 10 micro sec. - 10 sec. array is available in a 28 pin dual-in-line • Wide dynamic range (14-bit) package. Included in the assembly are • Correlated double sampling a single-stage thermoelectric cooler, • 800 - 1700 nm response silicon multiplexer, bias resistor and bypass capacitors. EVERYTHING Applications • Fiber optics, WDM monitor • NIR spectroscopy • NIR imaging • NIR astronomy • Far-field analysis MXA-256-X InGaAs Array Array MXA-256-X InGaAs PARAMETER CONDITIONS MXA-256-X 256 Number of elements 0.5 mm Pixel height 0.05 mm Pixel pitch 28 pin with 1-stageTE Cooler Package ±5pA "5pA Dark Current Response Typical @1550 nm 65 mV/pJ (0.97A/W onto 15 pF) Minimum@1550 nm 60 mV/pJ 800 to 1700 nm Wavelength response Response uniformity ±10% "10% @1550 nm Grade A 2% Grade A==none; none;Grade GradeB B≤ "2% Pixel dropouts 1.8fC Noise equivalent charge Full well capacity 100 KHz readout 15000ee- (150V (150µVonto onto15 15 pF) pF) 15000 Read noise NEP(pW/Hz (pW/Hz)1/2) @25˚C NEP @25 °C Optical range11 Optical Dynamic Dynamic range @ 2525˚C °C Dark voltage Dark voltage raterate 25°C @ 25˚C Dark voltage Dark voltage raterate 5°C @ 5˚C t = 1 msec 0.15 t = 100 msec 0.025 Tint <10ms Typical for 25˚C, Vn = 400µV t# 10msec -5˚C, VN = 150µV 42 dB(>13 dB (>14 bits) bits) 39 Typical pixel 0.6 V/sec Maximum pixel 6.0 V/sec Typical pixel 0.1 V/sec Maximum pixel 1.0 V/sec 10 KHz to 500KHz Pixel readout rate TE cooler (One stage) 400M e- (4V onto 15 pF) Hot side temperature 27°C Tmax=64°C @ 1.8A,8V T=45°C @ 0.85A, 5V(Nominal) -40°C to 70°C Storage Case operating temperature range No cooler With cooling Note 1: Optical Dynamic Range defined as: 10Vmaxlog(-Vdark/Vnoise) Vmax = 1.8 volts Vref = 3.5 volt 0° to 40°C -5°to 70°C Typical Performance Specifications at 25o C Standard Deviation of Dark Drift (V) (N=9, Tint=100ms) 8.0E-4 6.0E-4 4.0E-4 2.0E-4 0.0E-4 1 17 33 49 65 81 97 113 129 145 161 177 193 209 225 241 Pixel Number Responsivity 1.2 1 0.8 0.6 A/W 0.4 0.2 0 0.8 1.0 1.2 1.4 1.6 1.8 1E+0 1E+1 Wavelength (nm) (µm) 1300 NEP(W/√Hz) 1E-12 1E-13 1E-14 1E-15 1E-4 1E-3 1E-2 1E-1 Exposure Time (sec) Dark Current (pA) 4 2 0 -2 -4 0 80 160 Pixel Number 240 MXA-256-X MXA-256-X Multiplexed Array Schematic Diagram Note: Timing information as per PerkinElmer Optoelectronics MB Series Multiplexers Mechanical Specifications PIN # 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PIN OUT TABLE FUNCTION PIN # φ SH2 28 N/C 27 T.E.
