SMA 905 Connector
A precision SMA 905 Connector aligns to the
spectrometers entrance slit and ensures concentricity of the fiber. For
an upgrade fee that includes the cost of the custom connector and labor,
we will replace the standard SMA 905 Connector with a different connector
of your choice. We also offer connector adapters, such as an SMA-to-ST
Adapter and an SMA-to-FC Adapter. Please call for details on custom connectors
and adapters.Fixed
Entrance Slit
 Another option available with NIRQuest
user-configured
spectrometers is selecting the size of the entrance aperture. Entrance slits are
rectangular apertures, 1-mm tall and various widths from 10 m to 200 m,
with the width determining the amount of light entering the bench. Note
that the smallest slit achieves the best optical resolution. (For more on
how your slit choice affects optical resolution,

here.) A slit
is permanent; it only can be changed by our technicians. You can opt
against having a slit, in which case the diameter of the fiber connected
to the spectrometer determines the size of the entrance aperture.

Detectors
In our range of NIRQuest Spectrometers, we offer three
different InGaAs linear array detectors, one 512-element array and two
256-element arrays. The Hamamatsu detectors used in the NIRQuest Optical
Bench are InGaAs photodiode linear arrays with each pixel connected to a
charge amplifier array consists of CMOS transistors. These detectors
deliver high sensitivity and stable operation in the near infrared. The
detectors all include onboard thermoelectric cooling. A thermistor
monitors the array's temperature and a thermoelectric device can cool the
arrays to 35 C below ambient, keeping the array stable to within ?.1 C.
In addition, you can set and monitor the detector's temperature via
software. The detector is included with the price of the NIR Spectrometer.
