Frequently Asked Questions (FAQ)
What substrate materials are used for these bandpass filters?
These stock bandpass filters utilize Germanium (Ge) as the substrate material, which is ideal for infrared applications.
What is the size range available for these filters?
We offer custom size capabilities ranging from Φ0.1 mm up to 300 mm to meet various optical system requirements.
What is the average transmission (Tavg) of the filters in the passband?
The filters feature a high average transmission (Tavg) of ≥85% within the designated bandpass region.
What is the typical out-of-band transmission performance?
The average transmission (Tavg) in the cut-off area except for the passband is kept below 1% (<1) to ensure excellent blocking efficiency.
Can I request a custom size or wavelength range not listed in the table?
Yes. The table represents our current stock items. If you require custom specifications, sizes, or different spectral ranges, please contact us directly for custom fabrication options.
