High power laser optical components and measurement technology

High power laser optical components and measurement technology

In recent years, the development of high-power laser, deep ultraviolet/X-ray and other fields not only expands the choice of optical materials, but also puts forward the processing requirements of extremely precise surface and ultra-smooth surface for optical components. Therefore, it is very important to seek a breakthrough in new coating technology and realize dense and accurate film layer.

The Function of Optical Lens and the Law of Imaging

The Function of Optical Lens and the Law of Imaging

The function and imaging law of optical lens. The lens is an optical element made of transparent material, and its surface is a part of spherical surface. The lens consists of several lenses. There are two kinds of plastic lenses and glass lenses. The lens is made of a transparent material. Made of optical elements that affect the curvature of the light wavefront. It is a device that can converge or disperse light, and the resulting image has real and virtual images.

Introduction to the elimination of chromatic aberration in optical glass

Introduction to the elimination of chromatic aberration in optical glass

Achromatic (APOchromatic): It is conceivable that if the refractive index of a material can be arbitrarily controlled as a function of wavelength, then we can design a lens with no chromatic aberration at all. Unfortunately, the dispersion of the material cannot be controlled arbitrarily. We take a step back and imagine that if the visible light band can be divided into two intervals, blue-green and green-red, and these two intervals can be applied separately with achromatic technology, the secondary spectrum can be basically eliminated.

Judgment and Test Method of Wear Resistance of Abrasive Layer in Film Production

Judgment and Test Method of Wear Resistance of Abrasive Layer in Film Production

The material of the anti-fouling film in the optical glass coating is mainly fluoride. There are two processing methods, one is soaking method, the other is vacuum coating, and the most common method is vacuum coating. The most common method is vacuum coating. When the antireflective film layer is completed, the fluoride may be plated on the reflective film using an evaporation process.

Optical coating process

Optical coating process

The optical coating is realized in a high vacuum coating chamber. Traditional optical coating processes require elevated substrate temperatures (typically around 300°C), while more advanced techniques, such as ion-assisted deposition (IAD), can be carried out at room temperature. The IAD process can not only produce films with better physical properties than the regular coating process, but it can also be applied to substrates made of plastic.
