    Frequently Asked Questions

    1. What is the meaning of CWL and HPB in the product list?

    CWL stands for Center Wavelength, which is the peak transmission wavelength of the bandpass filter. HPB (Half Pass Band), also commonly known as FWHM (Full Width at Half Maximum), refers to the spectral bandwidth at half of the maximum transmission level.

    2. Which substrate materials are used for these bandpass filters?

    We manufacture filters using a variety of high-quality substrate materials depending on the optical wavelength requirements, including Sapphire, K9 Glass, White Glass, D263T, Quartz, Silicon (Si), and Germanium (Ge).

    3. Can I request custom sizes for the filters?

    Yes. While our standard sizes range widely, we can customize the dimensions of our bandpass filters from Φ0.1 mm up to 300 mm to fit your specific optical systems and instruments.

    4. What is the purpose of the blocking range parameter?

    The blocking range defines the interval of wavelengths that are effectively blocked or attenuated by the filter. Deep blocking ensures a high signal-to-noise ratio by preventing unwanted out-of-band light from reaching the detector.

    5. How can I obtain the specific spectrogram for a filter?

    Standard spectrogram previews are available in the product table. If you require high-resolution measurement data or batch-specific test curves, please contact our support team.
