Product Description

1. Why choose Sapphire?

Features Extreme Surface Hardness and Chemical Resistance
Transmits Wavelength Ranging from UV to Mid-IR
Thinner and Stronger than Standard Glass windows
AR coating for VIS or IR spectrum range

2. What are 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.

Frequently Asked Questions

Q: Why is sapphire preferred for laser systems? A: Sapphire is chosen for its extreme hardness, high thermal conductivity, and resistance to chemical erosion, making it durable under high-power laser stress.

Q: What is the typical transmission range for sapphire components? A: Sapphire offers a broad transmission range from 0.2µm (UV) to 5.5µm (Mid-IR).

Q: Can I request custom dimensions for the rod lenses? A: Yes, we offer customization for diameters ranging from 0.2mm to 300mm and various custom shapes.

Q: What surface quality standards do you provide? A: We typically provide surface qualities of 40/20 or 60/40, depending on the specific application requirements.

Q: Are AR coatings available for these lenses? A: Yes, we provide Anti-Reflective (AR) coatings for both the visible (VIS) and infrared (IR) spectrum ranges.

Q: How does sapphire compare to standard optical glass in thickness? A: Due to its superior structural strength, sapphire windows can be made much thinner than standard glass while maintaining better durability and transmittance.
