 +We found a (dead) ladybug in the lab (our cleanroom conditions are impeccable) and imaged it under the SEM. Look at its eyes!

 +Looking at a (sandpaper-)decapped chip under an optical microscope. The chip is positioned using the [[projects:micromanipulator:start|Open Micro-Manipulator]], which gives very convenient X/Y and focus control.

 +==== Plate Capacitor on Glass Slide (2026-09-05) ==== 
 +{{:gallery:20260905_plate_capacitor_measurement.jpg?600|}} 
 + 
 +A plate capacitor on a glass slide, as it is being measures in our wafer probing station. 
 + 
 +The capacitor is made from multiple layers of thin-film coating (Al and SiO₂) produced in our [[equipment:edwards-306:start|Edwards AUTO 306 Coating System]]. A lot more details about this experiment have been presented in our talk [[https://media.ccc.de/v/2026-733-vacuum-deposition-systems-and-you|Vacuum Deposition Systems and You]] at MRMCD26.

 +{{:equipment:edwards-306:20260827_fixture_plate_in_sputter.jpg?600|}} 
 + 
 +We got a new fixturing system for our vacuum coaters! It fits in both of our [[equipment:edwards-306:start|Edwards AUTO 306 Coating Systems]]. 
 +

 +Here it is after first getting coated with chromium.

 +==== Toilet Paper Imaging (2026-08-01) ==== 
 +{{:gallery:20260731_toilet_paper_sputtering.jpg?600|}} 
 + 
 +First we sputtered a tiny sample of toilet paper with chromium in our [[equipment:edwards-306:start|Edwards AUTO 306 Coating System]]...

 +==== Optical Imaging (2026-07-31) ==== 
 +{{:gallery:20260731_optical_imaging.jpg?600|}} 
 + 
 +Very professional setup for optical imaging of a random test wafer sample using our [[equipment:hitec-600-53:start|HITEC 600-53 Optical Microscope]].

 As part of our [[projects:optics:start|laser optics endeavours]], we attempted coupling light from a laser diode directly into a single-mode 635nm optical fiber. For alignment, we used the [[https://openflexure.org/projects/deltastage/|OpenFlexure Delta Stage]] (bottom left of the picture). As part of our [[projects:optics:start|laser optics endeavours]], we attempted coupling light from a laser diode directly into a single-mode 635nm optical fiber.
