Abstract
In this paper, chemical etching experiments were carried out on two K9 glasses with trailing indent cracks (TICs). The surface morphology of etched TICs and the optical properties of the glass with etched TICs are analyzed firstly. The results show that the transmissivity of the glass with TICs initially decreases and then increases with the increase of etching time. Conversely, the reflectivity initially increases and then decreases. This can be attributed to morphological evolution of TICs during chemical etching. Then, based on the fact that TICs are a series of spaced cracks, a simulation model is developed for determining the optical properties of the glass with etched TICs. The model is validated experimentally. It is found that the model is effective when the light wavelength is large and the TICs are uniformly distributed. This research contributes to improving the optical properties of polished optical glasses by chemical etching.
