Types of Insulating Glass in Optical Elements
Optical element insulating glass has a special ability to absorb, transmit, and reflect light and heat. The use of this glass in exterior windows and glass curtain walls for buildings can achieve significant energy savings. Commonly used thermal insulation glass includes heat-absorbing glass, coated glass, and insulating glass. How does heat-absorbing glass work? Heat-absorbing glass … Continue reading
Messier 106 Revealed
Tony Hallas provides another amazing image. This one shows Messier 106 (NGC 4258), which is found in the constellation Canes Venatici. M106 is located about 22 to 25 million light-years away from Earth. The photo was taken with over 10 hours of exposure in California, using Chroma Technology’s 27102 H-alpha, Luminance, Red, Green, and Blue (HaLRGB) astronomy filter … Continue reading
DIY Quantum Relays – Part 2
Quantum Relays are an exciting technology, enabling long-haul quantum communication without the need for trusted-node intermediaries. They also expand the algorithmic repertoire available for distributed quantum computing. In this workshop, Dr. Martin Felle explores some of the schemes for building a quantum relay, including the necessary components and sub-systems. In addition, he will discuss some … Continue reading
News from the NIST Post-Quantum Crypto Process
To counter the quantum threat, which will break current asymmetric cryptography, the National Institute of Standards and Technology (NIST) has launched a process to select and standardize new resilient algorithms (Post Cryptography Standardisation). The open selection process started in 2017, with a first round of 69 proposed algorithms, which were presented, analyzed, and attacked by … Continue reading
How to Clean Customized Optical Components
Although you may only clean your eyeglasses by simply wiping them with a cloth, that is not a suitable method to clean delicate, customized optical components. Optical manufacturers generally use ultrasonic cleaning, but many users do not have such sophisticated equipment. However, proper cleaning methods can improve the performance and longevity of your components. Handling … Continue reading
