Hey, I'm Fernando Ramiro Manzano, and this is our optical lab.
The first thing you can see in an optical lab is an optical table,
Here, various optical setups are interconnected. We will discuss them later.
Then on the right, you can see a water installation for cooling high power equipment.
Next, an old spectrometer used for extracting valuable optical elements.
This big box provides an uninterruptible power supply for the lab.
Then, our bench used for sample proparations, electronic adjustments, as well as a microscope for first inspections.
We preserve and repair ancient discrete power electronics for lasers.
Here, there's a second optical table. And now let's focus on the storage shelves.
Here, we storage different samples as well as different electrical probe tips, and cables, always present in physics labs.
Here, there's temporal storage of optical elements and different microscope objectives.
We have a catalog of optical lenses, as well as several optical filters.
There're several shelves for old and new equipment
Protection glasses for absorbing different spectral regions or let’s say, “colour ranges”
From time to time, we storage small parts of the setups.
Here there're tools, as well as screw sets.
And now our LEGO
A collection of opto-mechanical pieces such as cage plates, tubes, kinematic munts, positioners, rotation stages, different posts, posts holders, clamps, bases, etc.
We have different kind of mirrors, including focusing mirrors.
The optics must be cleaned carefully with their appropriate cleaning tools.
This is the shelf of optical fiber tools, patches and reels.
And now let's focus on the optical table.
Here we prepare, condition, measure and acquire various light phenomena.
We use different light sources, such as lasers that can be focused on micro-
or nano-metric samples.
In fact, we establish a precise nano-metrical control of the samples, objectives or electrical probes.
For a broadband illumination, we can use the supercontinuum source, that is like a white laser.
This light can be prepared and conditioned to extract its spectral components or let’s say “colours”
by using diffraction gratings in the visible near-
and the mid-Infrared. They are similar to prisms, but in reflection.
The gratings are the core of a commercial spectrometer. In any case,
and depending on the experiment, the signal is prepared and conditioned accordingly.
For example, the light can be polarized, phase-modulated, chopped, its beam profile selected or even made to interfere with itself.
Many times the commercially available devices do not fulfil our conditions. Thus, we create new ones that fit exactly our requirements.
Last but not least, the sample is observed and positioned using different camera systems and its signals are collected from different angles.
This allows us to acquire, for instance, light reflection, transmission, scattering and emission.
And then we arrive at the same point on the table where we started.
And now let's take a look to the connected
devices to the optical table: computer screens, lock-in amplifiers for isolating the
the desired modulated signal, light drivers and controllers, oscilloscope for acquiring time-domain signals, other light drivers on signal conditioners, one important device, the temperature controller and behind the array detector controllers, the computer.
Now let's put on or wear all the predictions switch off the lights, and rock'n'roll.
So, I hope that you enjoyed this visit,
So, see you.
