Why Choose sapphire crystal?

Today Sapphire is still a Stone of Wisdom, a royal stone of learning, mental acuity and psychic activation, a seeker after spiritual truth. Its pure Blue Ray brings order and healing to the mind, lending strength and focus, and an ability to see beneath surface appearances to underlying truths and to utilize that knowledge.

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm
