Rod lenses are mainly used in Sensors, light guides, and endoscopes, laser systems. Sunday can make polishing either the end faces or the cylindrical faces depending on customer's using.
Sunday can provide cylinder lens with positive or negative focal length,shape can be plano convex,plano concave,double convex,double concave,meniscus,achromatic or custom shape.
1. Why choose the sapphire?
Thinner and Stronger than Standard Glass Windows
Transmits Wavelengths Ranging From UV to Mid-Infrared
Features Extreme Surface Hardness and Chemical Resistance
2. What is sapphire windows
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.
