The students’ understanding of the equivalent air layer of planar optical element becomes easier and the related calculation is more convenient. While emphasizing the practicability and effectiveness of knowledge and skills, students' ability to acquire knowledge and use it flexibly can be greatly improved.", issn = "23495219", journal = "IJIRES", keywords = "Optical Instrument, Flat Optical Element, Equivalent Air Layer, Reflecting Prism", month = "January", number = "1", pages = "11-15", title = "{E}quivalent {A}ir {L}ayer in {O}ptical {S}ystem and {T}eaching {A}pplication", volume = "9", year = "2022", }
