Purpose: 
Anti reflective coating: 
Titanium pentoxide is often used as an anti reflective coating due to its high refractive index and good transparency. By coating a thin layer of Ti3O5 on the surface of glass or plastic, light reflection can be significantly reduced and transmittance can be improved, which has important applications in optical devices such as eyeglass lenses and camera lenses. 
Mirror coating: 
Ti3O5 is also widely used in mirror coatings. Its high reflectivity makes it an ideal material for mirrors in telescopes and laser systems. By depositing a layer of Ti3O5 on the mirror surface, the reflection efficiency and durability of the mirror surface can be improved. 
Filter coating: 
Filter is a key component in optical systems, used to selectively filter light of specific wavelengths. The unique optical properties of titanium pentoxide make it an ideal material for manufacturing optical filters, especially in multi-layer interference filters where the Ti3O5 layer can precisely regulate the transmission and reflection characteristics of light. 
Mechanical properties: 
The hardness and wear resistance of titanium pentoxide are also excellent. Its Vickers hardness is about 700 HV, making it perform well in high stress and high wear environments. Therefore, Ti3O5 is widely used in the field of protective coatings that require high wear resistance. 
Optical properties: 
Titanium pentoxide exhibits excellent optical properties, with a refractive index of approximately 2.4, making it an ideal choice for various optical applications. In terms of transparency, Ti3O5 exhibits good transparency in the visible and near-infrared spectral ranges, especially in the wavelength range of 400 nm to 700 nm.
