What surface roughness and flatness tolerances are guaranteed for the 4-inch quartz glass substrate?
The substrate is specified with a surface roughness of Ra <0.5 nm and flatness of <5 µm. These values are directly stated in the product specifications for the 4-inch (100 mm) quartz glass format, ensuring a high-quality optical surface suitable for demanding applications.
What is the thickness tolerance for the 500 µm quartz glass substrate and how does it impact optical path consistency?
The typical thickness is 500 µm with a tolerance of ±25 µm. This tight tolerance minimizes variation in optical path length across substrates, which is critical for interferometric setups and multi-substrate stacking where consistent phase delay is required.
What surface quality standard (Scratch/Dig) is specified for this quartz glass substrate and why is it important?
The substrate conforms to a Scratch/Dig specification of 40/20 per the product data. This standard defines the maximum allowable scratch width and dig diameter, ensuring low scatter and high optical clarity, which is essential for UV and precision optical applications.
Atomfair quartz glass substrate (SKU AF-WF-S-GLAS-04IN-G058) in 4-inch diameter with 500 um thickness provides Ra <0.5 nm surface roughness, <5 um flatness, and Scratch/Dig 40/20 surface quality, making it suitable for thin film deposition and optical applications. The ±25 um thickness tolerance is a consideration for thickness-sensitive processes.
Positive
- Ultra-smooth surface: Ra <0.5 nm roughness enables high-quality thin film growth and minimizes scattering in optical applications.
- Tight flatness and surface quality: Flatness <5 um and Scratch/Dig 40/20 ensure reliable performance in precision optical setups.
Trade-offs
- Thickness tolerance of ±25 um: The specified thickness tolerance may require screening for applications demanding tighter thickness uniformity, such as resonant cavity or interferometric devices.
