 +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]]...

 +...and then we imaged it in the SEM.

 +==== Optical Imaging (2026-07-31) ====

 +
 +Very professional setup for optical imaging of a random test wafer sample using our [[equipment:hitec-600-53:start|HITEC 600-53 Optical Microscope]].

 +What seems to be a test pattern in the corner of a CMOS image sensor chip. It was from a Canon EOS 4D MKII, a DSLR camera from 2008.
 +
 +First image is optical microscope ([[equipment:hitec-600-53:start|HITEC 600-53]]), second image is SEM ([[equipment:zeiss-dsm-962:start|Zeiss DSM 962]]).  There is a lot of dirt on the SEM picture because someone (...) forgot to clean the sample before imaging...

 +Here you can see the microlens array ontop of the bayer pattern (red, green, and blue filters) of the sensor.

 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.
