Frequently Asked Questions
Q: What substrate material is used for these bandpass filters?
These bandpass filters utilize Germanium (Ge) as the substrate material, which is highly suitable for infrared spectrum applications.
Q: What dimensions and sizes are available for the stock filters?
We offer a wide range of sizes for these filters, spanning from Φ0.1 mm up to 300 mm.
Q: What is the transmission performance (Tavg) in the passband?
The average transmission (Tavg) within the specified bandpass range is ≥85%.
Q: What is the blocking range and out-of-band transmission level?
The cut-off area except for the passband ranges from 1000 to 5500 nm, with an average out-of-band transmission (Tavg) of less than 1% (<1%).
Q: Can I request a custom bandpass filter if the stock items do not match my requirements?
Yes, if you require specific dimensions, substrates, or different wavelength ranges, please contact us directly to request custom fabrication.
