SKU: SCISDEX6M

The Sciencetech SCISDEX6M features a 6mm diameter sensor with a sapphire window, 8-12 V/W sensitivity and 7x10-9 noise-equivalent power. It comes with separate 6ft output and power cables. The power connector is DB9 female with Sciencetech universal pinout for connection to the SCIPWRMOD power and measuring system. Compatible with EOS PS-1 power supply or EOS LIA/PS-1 lock-in/power supply. Package: 2" dia. x 1" long with 1" dia. face mount and 1/4-20 side mount. Power requirements are ±8 volts to ±24 volts at ±8mA max. A sapphire window allows essentially flat response (±3%) 400nm-4µm. Electrical output is 10V/W (±20%) from DC to -3dB at typically 1.8Hz.

Sciencetech's thermopile detector is inherently flat in response from 100nm to >100µm but is window limited. It is useful for solar radiation measurements at power densities of 70-150mW/cm2. Thermopile detectors may be sensitive to temperature fluctuations and/or radiation from cell phones.

Window Option
A variety of windows are available besides the standard sapphire. The available options are sapphire, germanium, silicon, CaF2, BaF2, and KBr. Please speak to a Sciencetech representative so that our detector can best suit your needs.

Calibarion Options
Calibrate at specified wavelength(s): (±1% traceable 632.8nm) $243
±5% for each other selected wavelength 300nm - 5µm (±2%) $448
All = 100nm intervals from 300nm to 5µm with ±5% accuracy. $4976

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 and switches on rear of 1" longer packaging.

Sensitivity
Measured (and calibrated) in a 0.1 Hz bandwidth at 22°C using a 632.8nm source chopped at 0.25 Hz with 50/50% duty cycle. On board jumper converts sensitivity from total power to power density. Sensor area is 28.3mm2. Damage threshold => 500mW/cm2 , 140mW total power.
