Artwork assistance is available upon request.Diffraction grating glasses transform light waves into colorful spectral light.Our expert team will get right to work and produce your custom diffraction glasses in 7-10 business days - not including shipping time. Design Your GlassesĪdd a touch of professionalism to your course or organization with custom images, colors, messaging, and other branding. These custom diffraction glasses feature holographic diffraction grating embossed with a micro-prismatic surface, and the lenses are available in your choice of wavelengths: 13,500 line/inch, 1,000 line/mm, and 500 line/mm. This is the first time, for the best of the authors knowledge, that RL emission and RSB are reported for a glass-ceramic system.Although diffraction grating is a scientific tool, our incredible glasses are an absolute blast for curious folks of all ages. The Parisi overlap parameter was determined for all samples, for excitation below and above the EFE th. With a full line of high-quality, holographic lenses, you can turn any party, event, lightshow, or even classroom lessons into the most memorable visual experience around. Moreover, the phenomenon of Replica Symmetry Breaking (RSB), characteristic of a photonic-phase-transition, was detected by measuring the intensity fluctuations of the RL emission. Customer Service 800.821.5122 If you’re looking for a brand new way to explore the world, it’s time to get your hands on a pair of diffraction glasses from. Our 500 line/mm holographic diffraction glasses are ideal for education purposes, where students can view the color spectrum in a new and unique way. These amplify any light and all color more than other diffraction lenses, making them ideal for studying gas light tubes and diffraction gratings. Put on our holographic diffraction glasses and you’ll be able to study and analyze light Experience an axis of colors as you view the color spectrum of any light source. The enhanced performance is attributed to the residence-time growth of photons inside the sample and the higher quantum efficiency of Nd 3+ incorporated within the microcrystals, where radiative losses are reduced. Plastic Diffraction Glasses for Education Our diffraction grating lenses are the perfect glasses for educational purposes since they’re 30 more efficient than most other diffraction lenses. The RL performance was clearly enhanced for the sample with the highest crystallinity degree whose energy fluence excitation threshold (EFE th) was 0.25 mJ/mm 2. The Random Laser (RL) was excited at 808 nm, in resonance with the Nd 3+ transition 4I 9/2 →, and emitted at 1068 nm (transition 4F 3/2 → 4I 11/2). Powders with grains having average size of 2 µm were prepared by griding the GCs samples. Photoluminescence (PL) enhancement of 500% relative to the parent glasses was observed for samples with a higher crystallinity degree (annealed during 5 h). The partial crystallization of the parent glasses was verified by X-ray diffraction. laser-structured in photoresist and glass but lack precision in phase. ![]() ![]() Glass samples were fabricated by conventional melt-quenching technique and the GCs were obtained by carefully devitrifying the parent glasses at 830 ☌ for different time intervals. for Optical Sciences, University of Toronto, 10 Kings College Road, Toronto. We investigated the random lasing process and Replica Symmetry Breaking (RSB) phenomenon in neodymium ions (Nd 3+) doped lead-germanate glass-ceramics (GCs) containing MgO. ![]()
