FAQs about ITO/FTO Coated Glass
Can you produce filters with specific wavelength ranges or bandwidths?
Yes. We design and coat filters according to your exact specifications — including central wavelength (CWL), full width at half maximum (FWHM), and transmission/reflection requirements.
What coating technologies are available?
We use advanced thin-film coating processes such as Ion-Assisted Deposition (IAD) and hard oxide coatings, ensuring high durability, stable performance, and excellent adhesion.
What substrate materials do you use for filters?
Common materials include borosilicate glass, fused silica, BK7, D263T, sapphire, and quartz. Each material can be selected based on optical performance, thermal stability, or mechanical strength.
What surface quality and flatness can you achieve?
Our optical filters meet up to λ/10 flatness and 10–5 surface quality (scratch-dig) depending on design and material requirements.
How can I request a quotation or sample?
Simply send us your filter specifications (wavelength range, size, coating type, quantity) via our contact form or email, and our engineering team will respond with a detailed quotation.
