Specifications for Sciencetech SCIEL420BJ-0 (windowless)
pyroelectric repetitive pulse energy sensor:

 

Spectral range 100nm - 1mm.
Element size 2.7 x 2.7 mm.
Maximum incident energy density 1.0e-3 Joule
Maximum peak absorbed power 1.0e+6 Watts (1ns pulse width)
Responsivity 25 V/W, 5Hz-6kHz (typical 3dB points)
NEP 5.2e-8 Watts (1Hz bandwidth)
Pulse energy sensitivity 1V peak/uJ +/- 50%
(1nS-5uS pulse width)
NEE 1.6e-11 Joules (1Hz bandwidth)
Output pulse decay TC 26 uSec
 (typical)
Output pulse polarity Negative
Tested repetition rate 1kHz

 

It is expected that pulse widths much shorter than specified above will be detected with the same sensitivity but this has not been tested.

Power connections DB-9 Pins 1 - 5 no connection
+V In Pin 6
-V In Pin 7
Common Pin 8
Case GND Pin 9

 

Power cable: 6 ft. with DB-9F connector.

Output cable: 6 ft. with BNC connector.

 

Package: 2" diameter black anodized aluminum, 1" high.

 

 

Window Option

A variety of windows are available besides the standard quartz or fused silica. The available options are sapphire (180nm - 4500nm), germanium (2000nm - 14000nm), silicon (1200nm - 7000nm), CaF2 (170nm - 7800nm), BaF2 (300nm - 9500nm), and KBr (210nm-28000nm). Please speak to a Sciencetech representative so that our detector can best suit your needs.

 

Lockin Module

Piggyback synchronous detector board is added internally to head. Accepts external reference OR performs homodyne detection on signal equal to or greater than 0.1% of full scale. Unity gain, TC=0.1/1.0sec. Additional power requirement: ±8 volts to ±24 volts at ±5mA max. BNC reference connector + switches on rear of 1" longer packaging.
