Q1: What substrate materials are available for these wide bandpass filters?
We offer a variety of substrate options based on the target wavelength ranges, including Sapphire, Silicon (Si), Germanium (Ge), Quartz, JGS3, Glass Ceramic, and D263T.
Q2: Can the size and dimensions of the filters be customized?
Yes, our standard size range is from Φ0.1 mm to Φ300 mm. Custom dimensions, shapes, and thicknesses can be engineered to fit your specific optical system requirements.
Q3: What does the "WBP" prefix represent in the product codes?
"WBP" stands for Wide Bandpass Filter. It indicates that the filter is designed to transmit a broad spectral band while blocking out-of-band wavelengths on both the shorter and longer sides.
Q4: What are the typical transmission and blocking levels of these filters?
Most of our filters feature high average transmission (Tavg ≥ 80% to ≥ 90%) in the passband and deep blocking levels down to Tavg < 1% or < 0.1% in the rejection bands.
Q5: How can I request custom spectrogram data or custom specifications?
If you require specific coating designs, angle of incidence (AOI) adjustments, or detailed spectrogram curves, please use the "contact us" link to get in touch with our technical team.
