Optical Windows are flat, parallel optical components designed to transmit light while isolating sensitive internal components from harsh external environments (dust, moisture, pressure, or temperature). Our optical windows deliver exceptional high transmittance, low reflection, and superior surface accuracy, serving as critical protective barriers in precision optical systems. The materials are including: N-BK7 / K9 Glass,Sapphire (Al₂O₃),Calcium Fluoride (CaF₂),Magnesium Fluoride (MgF₂)
