Frequently Asked Questions (FAQ)
What substrate materials are available for these bandpass filters?
We offer standard bandpass filters with Quartz and Silicon (Si) substrate materials, designed to ensure high performance across different spectral ranges.
What dimensions and sizes are available?
Our stock items support sizes ranging from Φ0.1 mm to 300 mm. Custom dimensions can also be tailored to match your specific optical configuration.
Can I customize the center wavelength (CWL) and bandwidth (HPB)?
Yes. If our stock specifications (e.g., CWL, HPB) do not meet your exact requirements, please contact us directly to request custom optical coatings.
What is the blocking range capability of these filters?
Our bandpass filters feature wide blocking ranges, spanning from 400 nm up to 11000 nm, to effectively suppress out-of-band noise.
How can I view the spectral transmission curves?
You can view the detailed spectrogram for each filter model by clicking on the thumbnail images in the "Spectrogram" column of our product table.
