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 Optical Prisms? The optical prisms are vital optical glass components after grinding and polishing. They are present in our daily life and are used in various devices such as cameras. When light passes through a prism, the prism changes direction depending on the geometry and refractive index of the material. This property allows…
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…
An optical window is a flat, transparent optics that allows light to pass through without altering its wavelength or direction. It is primarily used to isolate different environments while protecting sensitive optical systems. You can choose the window that suits you based on the transmission characteristics of the material and the usage environment. T The…
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…
The lens definition The optical lens is usually made of common materials such as glass, BK7, quartz, and sapphire. Their function is to change the direction of the light through refraction or reflection. Therefore, they can achieve image focusing, magnification, or correcting optical aberrations, etc. You may not have seen it, but it is an…
What is a TIR lens? TIR Lens (Total Internal Reflection Lens) are specially designed optical lens that use the phenomenon of total internal reflection of light within the lens and between the inner surface and the outer surface. This enables precise control of light, such as focusing, collimation, or uniform illumination. It is commonly used…
Understanding current trends in optical components is crucial for modern applications. These trends significantly impact various industries, driving innovation and efficiency. The global advanced optics market, for instance, is projected to grow from USD 301.70 billion in 2024 to USD 707.70 billion by 2034, reflecting an annual growth rate of 8.9%. This growth highlights the increasing…
