Frequently Asked Questions (FAQ)
Q: What is the substrate material used for these filters?
These dual-band bandpass filters utilize Germanium (Ge) as the substrate material, which offers excellent transmission properties in the infrared spectrum.
Q: Can I request custom sizes for the filters?
Yes, we support custom size specifications ranging from Φ0.1 mm up to 300 mm. Please contact us to specify your dimension requirements.
Q: What is the average transmission (Tavg) in the passband?
The average transmission (Tavg) for our stock dual-band bandpass filters is ≥85% within the specified passband ranges.
Q: What is the typical blocking/cut-off performance?
The filters provide high out-of-band blocking with an average transmission (Tavg) of less than 1% (<1%) across the cut-off range of 1000nm to 5500nm.
