Basic (standard shroud)
By default, and if no other option is chosen, the attoDRY800 cryostat is delivered with
the basic vacuum shroud. It constitutes a geometry which is almost identical to what
hundreds of labs worldwide have been using for decades with their flow cryostats.
Designed for room temperature optics, the sample sits on a manually adjustable holder
at a typ. minimum working distance of about 3.5 mm. In addition to 88x M6 breadboard
mounting holes on a 12.5 mm grid, it also features a 30 mm and 60 mm cage system
threads and adapters.
LT
version
LT-APO objective
HV
version
RT
version
Our unique LT-APO low temperature objectives with high numerical apertures allow to
maximize the collection efficiency over a broad wavelength range when optical signals
are weak such as from single photon sources. Since sample and objective are both cold,
this configuration also maximizes the overall stability of the setup. In the standard
configuration, the sample sits on an xy positioner stack with optional scanner, while
a z-positioner on the objective mount serves for focussing motion.
LT
version
Photonic Probe Station
HV
version
RT
version
Photonic Integrated Circuits (PIC) are hot candidates for becoming the key components of the
next generation of optical and quantum communication systems. The Photonic Probe Station
vacuum shroud allows for integration of two optical lensed-fiber probes from the side for
coupling light into planar waveguides, and a free-beam confocal top access for nano photonic
device characterization. In addition, the vacuum shroud offers side access with an additional
room temperature objective from the outside.
