Sapphire Lenses are suitable for high power, high-pressure applications, and vacuum or corrosive atmospheres. The material is extremely hard and resistant to attack by strong acids. It has high compressive strength, a high melting point, and excellent thermal conductivity. Transmission range is from 150 nm to 5 µm.
Sapphire Lenses
Series optical grade sapphire lenses are manufactured from optical grade grown sapphire. Monocrystalline sapphire is slightly birefringent. The lenses are available in positive and negative configurations. Typical applications include:
