Global Thin-Film Optical Filters Market Growth 2025-2031

The global Thin-Film Optical Filters market size is predicted to grow from US$ 230 million in 2025 to US$ 325 million in 2031; it is expected to grow at a CAGR of 5.9% from 2025 to 2031.

Thin-film optical filters are made by depositing alternating thin layers of materials with special optical properties onto a substrate, such as optical-grade glass. As light makes its way through the optical filter, its direction changes as it passes from one layer to the next, resulting in internal interference. This is due to the differences between the refractive indices of the materials in the dielectric thin-film coating. The configuration of the layers results in an optical filter that manipulates different wavelengths of light in different ways. Depending on the wavelength and type of optical filter, light can be reflected off of the filter, transmitted through it, or absorbed by it.

The global key manufacturers of thin-film optical filters include Edmund Optics, Chroma Technology, Alluxa, and Semrock (IDEX), etc. Global top four players hold a share over 20 percent. North and Europe are key producers of thin-film optical filters, both has a share over 50%.

In terms of products, Dichroic Filters is the largest segment, with a share about 34%, while in terms of application, Biomedical and Life Sciences is the largest application, occupying for a share over 50%.
