The Camera Quark unit is a powered Fabry-Perot etalon
that is placed between your lens and DSLR camera using the included Canon or Nikon adapter.
This technique uses a broadband Fabry-Perot etalon
to provide the calibration spectrum; the etalon is stabilized by referencing it to an atomic transition using standard laser spectroscopy methods.
These modules feature a monolithically integrated laser modulator chip, integrated Fabry-Perot Etalon
filter and two photodiodes, low dispersion penalty, low modulation voltage and low power consumption.
The feedback loop incorporates a tuned Fabry-Perot etalon
to provide a sharp optical frequency reference that maintains a high degree of absolute wavelength stability.
The Combo Quark unit is a powered Fabry-Perot etalon
that is placed between your diagonal and eyepiece to produce high-contrast views of the Sun's dynamic chromosphere.
In order to realise a frequency standard conforming to the above specification, we have identified that it is essential to use the Force-insensitive Fabry-Perot etalon
for portable optical local oscillator providing optical source for high-stability.
28 nanometers) using the Fabry-Perot etalon
in the Netherlands presented a singlechip CMOS microspectrometer containing an array of 16 addressable fixed-cavity Fabry-Perot etalons
, photodetectors, and circuits for read-out, multiplexing, and driving an ISS sensor bus.
In August 2001, Spectra-Physics introduced a new line of miniature Fabry-Perot etalons
to ensure optical wavelength accuracy and stability in telecommunications components.
We are using newly refined techniques of two-dimensional spectroscopy that rely on tunable, narrowband filters known as Fabry-Perot etalons
