    Frequently Asked Questions
    Q1: What substrate materials are used for these wide bandpass filters?
    A1: We utilize a variety of premium substrate materials depending on the transmission range, including Sapphire, D263T glass, Glass Ceramic, Silicon (Si), Germanium (Ge), Quartz, JGS3, and Zinc Selenide (ZnSe).
    Q2: What dimensions and sizes are available for the filters?
    A2: Our standard size range spans from Φ0.1 mm up to 300 mm. Custom dimensions, shapes, and thicknesses can also be manufactured to meet your specific optical design needs.
    Q3: How do the "50% Cut on Left" and "50% Cut on Right" values define the filter's performance?
    A3: These values represent the cut-on and cut-off wavelengths where the transmission drops to exactly 50% of the peak value, defining the boundaries of the bandpass transmission range.
    Q4: Can I request a custom wide bandpass filter if my required specification is not listed?
    A4: Yes. The listed items represent our standard stock. If you need custom wavelengths, specific blocking (OD values), or alternative substrates, please contact us directly for custom optical coatings.
    Q5: Are spectrograms and transmission curves available for these filters?
    A5: Yes, detailed spectrograms are available for all products. You can click on the spectrogram column image in the table to view the full transmission and blocking curve data.
