Autofluorescent LEDs
Autofluorescent LEDs

These are LED from the Iphone Lamp showing autofluorescent. A microscope with 10x/0.3 objective, a VIS LED lamp (420-700nm) and a filter set EX BP 400-440, BS 465, EM 470-900 were used to generate the autofluorescent. The image is a mosaic of 15 individual images with the following dimension: a. Scaling per pixel : 0.721x0.721um b. Image size: 1936x1460 pixels 1.40x1.05mm

Laser Induced Damage
Laser Induced Damage

Laser induced damage in a thin-film stack produced by focused short pulse, NIR beam. Multiple layers have been ablated, and the textures in different regions present different materials in various stages of ablation. The overall damage shape is an imprint of the beam profile of the laser, which had irregular shapes and hot spots in its low-intensity periphery. Image acquired using differential interference contrast microscopy (Leica Polarizing Microscope, 50x objective).

An Incarnadine Sky
An Incarnadine Sky

This is a photo taken at the top floor at Centre for Nano Science and Engineering department, IISc, on 2nd December 2020. On this day at around 6 in the evening, the sun set early and the clouds were neither too dense nor light such that the twilight from the Sun got scattered in all directions in a longer red wavelength due to numerous clouds. The lower wavelengths don't scatter as much as the red. This pic was taken using a high resolution Redmi Note 7 Pro smartphone camera.

Colored Light Drawing
Colored Light Drawing

Inspired by Picasso’s famous ‘Light Drawings’, the colored light drawing is performed using a moving white LED captured in a long exposure image. While the LED is white, colors are achieved using the prototype of the dynamic phase-coded camera, originally designed to encode motion-color cues in dynamic scene acquisition to achieve non-homogenous blind image deblurring (as presented in Elmalem, et al., "Motion deblurring using spatiotemporal phase aperture coding," Optica 7, 1332-1340 (2020)). Example to Picasso's famous ‘Light Drawings’ (our inspiration to the photo)- https://www.life.com/arts-entertainment/behind-the-picture-picasso-draws-with-light/ Link to our paper describing the dynamic phase-coded camera- https://doi.org/10.1364/OPTICA.399533 The image was taken in our lab at TAU.

Laser engraving DIC
Laser engraving DIC

Laser engraving on a cellphone chip observed using DIC contrast technique in reflected light. I used a 50x/0.8 objective. The colors observed in the image are not the colors of the piece itself but the interference colors where the tones yellows, orange and red are coincident with zones with residual stress.

Evolution of Vacuum Tubes
Evolution of Vacuum Tubes

X-ray image depicting a snapshot of the evolution of vacuum electron tubes. Left to right: a 1922 Western Electric 216A; a 1936 RCA 6F7; and a 1942 Sylvania 6SL7GT. Vacuum tubes brought the dawn of the age of electronics in the early twentieth century before they were replaced by transistors after the 1950s. Today, most types of vacuum tubes have been substituted by transistors or semiconductor devices. Image taken with an X-ray system (ZEISS Xradia Context).
