💡Our paper "Dispersion-engineered Floquet-Bloch phonon polaritons for extreme infrared beam control" is accepted! Polaritonic materials are thought to be unusable for light control, but we show that periodic structuring makes these materials actually quite useful. Read here: lnkd.in/d8-GT4QY

Call for data for survey of CCD spectrometers. Do you have a CCD spectrometer? If you do, would you please collect two fluorescent lamp spectra and send me the data in ascii format. One with the 546nm just a little bit below saturation and another at about 1/4 of that intensity. Thank you.
TCD1304 or S11639-01 Why you might choose the TCD1304 over the S11639-01 in most instances. 1) TCD1304DG $18 on Digikey, vs $200 to $450, and not found even on octapart. 2) Response spectrum, S11639-01 left, TCD1304DG right - self explanatory.
Teams from Johns Hopkins University & @bostonu.bsky.social demonstrate a retina imaging technique that digitally refocuses scans after capture. It removes the need for precise alignment, delivering sharper images & faster diagnosis. 👁️ #BiophotonicsDiscovery #Optics Read more: https://bit.ly/4mZ34Kq
The best of 3D-printers is here, by hacking them into lab equipment
Our 6-hands review/perspective: "Hacking 3D printers as laboratory robots" is now on ChemRxiv. In there, we show how many robots you can make by simply modifying a 3D printer. #chemsky 1/n with @sandersays.bsky.social and @supersciencegrl.co.uk chemrxiv.org/engage/chemr...
The culmination of many years work. One of the most advanced light-sheet microscopes in the world! -> A large field of view Snouty light-sheet microscope, with any immersion remote refocus and real-time multi-angle projections! For details see previous posts and here: github.com/amsikking/HT...
I've been tracking low-cost spectrometers on AliExpress, but when I come across these ~$300 spectrophotometers, that closely resembles Ocean Optics' Czerny-Turner optical layout, I am very impressed.
There are so many budget friendly portable spectrometers available, I thought I'd post some photos of when I opened one, an hopocolor HPSC330, to replace the battery and recalibrate it afterwards. It seems to use a crosses Czerny-Turner geometry with a linear CCD

1/3 We just turned a $25 fitness tracker into a water quality monitoring device (Colorx). The results are now published. doi.org/10.3390/s251... This is a follow-up of our ODX paper where we hacked a #fitnesstracker for bacterial growth monitoring. #WaterQuality #Sensors #odx
PIS IN SPACE! Today's video on CubeSats was over a year in the making—and deals with two of my favorite things: Raspberry Pis, and space! Also making a special guest appearance is Gabe from saveitforparts, using SDR to track sats: www.youtube.com/watch?v=qvN3...

HELL YES. Proof of concept for PWM (Pulse Wave Modulation) dimming of an inductive LED using a MOSFET as the gate! This isn’t the final pulse cycle - I’ll tweak that tomorrow, but it’s getting the full brightness and doing the dimming seamlessly! Woohoo!
Printed a new version of the heart that increases the diffusion a little better and distracts from the “two points of light” vibe a bit. (Basically I just moved the LEDs further from the surface and gave them more resin to shine through - does the trick!)
Back for a little while here, I tried this ‘starter pack’ for photonics & optics people: anyone else can follow up to 50 people at the click of a button: go.bsky.app/QrtPj7R. Put your name below and I will add you to the pack.
1/8 🧵 Update on the Pocket #Spectrometer project. Been working on upgrading from the AS7341 to AS7343 sensor. The #AS7341 worked well but only had 9 channels. The #AS7343 offers 12 channels which should be better for #colorimetric analysis. #OpenSource 💡
Our paper, "A gradient atmospheric model reveals enhanced radiative cooling potential and demonstrates the advantages of broadband emitters", is now online in Laser & Photonics Reviews. The work was led by Yeonghoon Jin onlinelibrary.wiley.com/doi/10.1002/... 🧪💡
A Gradient Atmospheric Model Reveals Enhanced Radiative Cooling Potential and Demonstrates the Advantages of Broadband Emitters
We introduced a model for sky-facing radiative cooling that accounts for altitude-dependent temperature and gas composition at specific times and locations on Earth. Our results suggest that radiativ....

Currently preparing 10 #DIYNAFLUOR kits for grade 10 students to assemble as a part of a science outreach program run by my institute. They will use the DIYNAFLOUR to quantify fluorescent nanoparticles they get to synthesize. (Wish I got to do this when I was 15. 😅 🦕)

Hello 💡community, recently I saw a post most likely on LinkedIn comparing different #FDTD softwares, both open source and commercial ones. It’s like a table. If anyone finds it please post it here.
1/14: As a DIY enthusiast who loves #spectrometers and💡, I am excited to share the story of LaoKang, a Chinese maker who turned a #DIY hobby project into a €67 #spectroscopy product. His "Garden Spectrometer" is making spectroscopy accessible by bringing a €1000+ tool for under €67 ($75)🧵👇.
If you are in Europe, get this cute microscope for just €5 at #smythtoys. It has illumination, color filters, multiple lenses, and prepared slides. I'm modifying it with an #ESP-CAM and scanning stage to make automated #diy scanning microscope.
