Sight Glass Stress Test
A really quick blog here. The introduction of the iPhone 6 lead to a flurry of questions about Sapphire vs Gorilla Glass as the main screen surface. We did a related test where a sapphire window was impacted by a … Continued
Laser Window
Lately we’ve been busy with building sapphire laser windows for the industry. Second to only diamonds in mechanical strength sapphire is the choice for not-so-easy-on-it applications. Sapphire laser windows are scratch resistant, have a wide transmission spectrum of light, (from 200nm to 6µm) and … Continued
Laser Window for High Pressure Steam Application
The world we live in is at ambient temperature. We have things to deal with it if temperature gets out of control. Heaters or air conditioners, depending on the season. The world of engineering is not like that. Temperatures in … Continued
Soda Lime Glass Transmission Curve
We compared how much energy is transmitted through a soda lime glass vs. sapphire. In a nutshell, soda lime glass is better than sapphire, transmitting more of visible light in the 475 – 590 nanometers spectrum. This spectrum covers the … Continued
Impact Test of a Laser Window Made of Sapphire Bonded to a Stainless Steel Housing
Summary Test samples simulating sapphire laser windows were subjected to an impact test where a steel ball was dropped onto the test sample. The impact test of a laser window made of sapphire demonstrates that the sapphire was cracked upon … Continued
Laser Windows Made of Sapphire
Laser windows are simple devices. Their sole function is to let the light pass through an impenetrable wall. Impenetrable for everything but the light, that is. The light passing through a laser window has a particular energy, and a particular … Continued
