tự chuẩn trực
Definition
- Noun:
- Autocollimator: A precise optical instrument used to measure small angular deviations by projecting a collimated beam of light onto a reflector and observing the reflected beam's return path. It is fundamental in metrology for aligning components and testing the flatness of surfaces.
Usage Examples
- Noun:
- Kỹ sư sử dụng tự chuẩn trực để kiểm tra độ phẳng của bề mặt gương. (The engineer uses an autocollimator to check the flatness of the mirror surface.)
- Tự chuẩn trực là thiết bị không thể thiếu trong phòng thí nghiệm quang học. (The autocollimator is an indispensable device in the optics laboratory.)
Advanced Usage
- The term is a compound noun in Vietnamese, directly equivalent to the English technical term "autocollimator." Its usage is almost exclusively confined to technical fields such as optical engineering, precision mechanics, and scientific metrology.
