Optical Design of a Laser Scanning System Stable Against Wavelength and Temperature Variations Kim, Da Ae; Lee, Jong-Ung;
The characteristics of an optical system vary depending on wavelength and ambient temperature. Based on the thin-lens approximation, we investigate the conditions for stabilizing an optical system against wavelength and temperature variations at the same time. The conditions are applied to designing a laser scanning system consisting of two lenses. The change in the effective focal length of the scanning system against wavelength and temperature variations is very small, as expected.
