FAQ - Frequently Asked Questions
Q1: What substrate materials are available for these bandpass filters?
We offer bandpass filters on a variety of high-performance substrates including Sapphire, Silicon (Si), Germanium (Ge), Quartz, K9 Glass, BF33, and D263T to suit different wavelength ranges and thermal requirements.
Q2: What sizes can you manufacture for these optical filters?
Our standard manufacturing capability supports optical filter sizes ranging from diameters of Φ0.1 mm up to 300 mm, catering to both micro-optics and large-scale optical systems.
Q3: Can I request a custom Center Wavelength (CWL) or Half Peak Bandwidth (HPB)?
Yes. While the table shows our current stock items, we specialize in custom optical coatings. If you require specific CWL, HPB, or blocking ranges, please contact us for a customized solution.
Q4: What is the typical peak transmission (Tp) for these filters?
Most of our bandpass filters achieve high peak transmission rates of ≥80% or ≥90%, depending on the specific design, substrate material, and target wavelength range.
Q5: What blocking range options do you provide?
Our filters feature wide out-of-band blocking ranges, typically extending from UV up to far-infrared (e.g., 400 nm to 30000 nm), ensuring excellent signal-to-noise ratios for your optical systems.
