What is an Optical coating? An optical coating, also called film coating, is used to the surface of substrates to adjust the reflection, transmission, or absorption of light. The optical coating may be a single layer or multiple thin layers materal. And the materal can be the mental or other dielectric coatings. By carefully designing…
What are Aspherical Lenses? Aspherical lenses are optical components with a non-spherical surface curvature, meaning its radius of curvature changes across the lens surface. This unique design addresses a critical limitation of spherical lenses: optical aberrations. The advantage of aspherical lenses is that they can correct spherical aberration. Spherical aberration is an optical effect that…
What is a colored filter? The Colored optical filter is an optical component made of optical glass or dyed glass materials. It achieves spectral regulation by selectively absorbing or transmitting specific wavelengths of light. Unlike coated filters, the filtering performance of colored filters stems from the composition of the material itself, thus possessing excellent stability…
