Technical Knowledge

We already know that the transmittance is related to the refractive index of the coating, but not about its thickness. However, if we can work

According to the basic theory of electromagnetism, transmission and reflection for different media are mentioned. If it is vertically incident from medium N1 to N2

The optical film is realized in a high vacuum coating cavity. The conventional coating process requires increasing the substrate temperature (usually about 300 ℃); More

Optical coating refers to the process of coating a layer (or multiple layers) of metal (or medium) film on the surface of optical parts. The

Glass coating is to coat one or more layers of metal films or metal compounds on the surface of glass to change the optical properties

1. Related concepts of cold reflection Cold reflection is a common stray light effect in cooled infrared system. The cooled infrared detector usually works at

Understanding optical parameters In the design and production process of components or systems, the use of optical parameter specifications can make the components or systems

From the optical path, it is obvious that the angle of 45 ° angle needs to be carefully controlled in order to meet the requirements

The application of thin film and optical devices in our daily life; For example, glasses, digital cameras, various household appliances, or anti-counterfeiting technology on banknotes
