Frequently Asked Questions (FAQ)
Q: What substrate materials are used for these optical filters?
Silicon (Si) and Germanium (Ge) substrates are utilized depending on the specific optical wavelength range and requirements of the filter.
Q: What size ranges are available for the filters listed?
Our standard size capabilities range from Φ0.1 mm to 300 mm, allowing us to support both micro-optics and large-aperture applications.
Q: What is the significance of the "Tavg" value in the specifications?
"Tavg" represents the average transmission percentage within the specified passband. Our stock filters guarantee average transmission rates of ≥80%, ≥85%, or ≥93% depending on the model.
Q: Can I request a custom spectral range or custom cut-off areas?
Yes. If the current stock items do not meet your exact requirements, we offer custom optical coating designs. Please contact our team to discuss your target specifications.
Q: How can I view the spectrogram for a specific filter?
You can click on the image thumbnail in the "Spectrogram" column of the product table to view the full spectral transmission graph.
