We have many advanced testing instruments, which can detect the size, thickness, flatness, surface shape, appearance, profile, optical splitting, etc., of high-precision optical components. We use quadratic element projectors, contourgraphs, and coordinate measuring machines to inspect the contours of our products. We employ ZYGO interferometers and laser interferometers for surface testing and utilize spectrometers and the Carry 7000 versatile spectrophotometer spectrophotometer for spectral testing, and other reliability tests to verify the major projects effectively. The accuracy of the relevant high-precision instruments is at least the micron level, and even higher can detect the nanometer level.
