Frequently Asked Questions
Q1
Which substrate materials are used for these optical filters?
Silicon (Si) and Germanium (Ge) substrates are used, depending on the specific filter model and its wavelength requirements.
Q2
What dimensions and sizes are available for the filters?
Our standard stock filters are available in size ranges from Φ0.1 mm to 300 mm.
Q3
What is the typical average transmission (Tavg) performance?
Depending on the specific filter design, the average transmission (Tavg) is highly optimized, reaching values of ≥80%, ≥85%, or even ≥93%.
Q4
How effective is the out-of-band blocking for these filters?
These filters feature precise cut-off areas with average transmission (Tavg) values under 1% or 2% in the blocked ranges to ensure maximum performance.
Q5
Are custom filter designs or non-stock sizes available?
Yes. If you cannot find the specific dimensions or optical properties you need in our stock list, please contact us directly for custom configurations.
