The applications of vacuum coating CVD electric furnace in optics are as follows:
1. Preparation of high-quality optical thin films:
Anti reflection film: CVD technology prepares thin films with anti reflection effects by precisely controlling the thickness and refractive index of materials. For example, depositing an anti reflection film on the surface of optical components such as camera lenses and glasses can reduce reflected light, improve transmittance, and significantly enhance imaging quality.
High reflectivity film: used in devices such as lasers and astronomical telescopes, typically designed with multiple layers of film to enhance reflectivity. CVD technology can provide uniform and dense thin films that meet the requirements of high reflectivity, while combined with ion beam assisted deposition (IAD) process, it can enhance the stability of the film at high power.
Wave Plate Film: CVD technology can prepare high-quality wave plate films for controlling the polarization state of light, which have important applications in optical communication, optical sensing, and other fields.
2. Manufacturing optical components:
Optical lenses: In the manufacturing of optical lenses, CVD technology can deposit functional film layers such as anti reflective and reflective coatings to improve the optical performance of the lens, reduce reflection and glare, and make imaging clearer.
Filter: including bandpass filter, long wave pass and short wave pass filter, widely used in spectrometers, microscopes and communication systems. CVD technology achieves filtering effects by selectively transmitting specific wavelengths, meeting the needs of different optical applications.
3. Implement special optical functions:
Color filter: By precisely controlling the number of layers, thickness, and refractive index of the film, CVD technology can be used to prepare color filters for display devices, optical sensors, and other fields, achieving precise color control and display.
Beam splitter and dichroic mirror: CVD technology can prepare beam splitters and dichroic mirrors with specific splitting ratios, which are used in optical experiments, laser systems, and other fields to achieve precise beam splitting and wavelength selection of light.
