WebApr 13, 2024 · Optics, not wavelength, determine the effective range. How does the distance between the sensor and the sensing object be taken as a factor in selection of wavelength? More power will give you longer range, but optical power is limited by safety. Using NIR (or better, IR) wavelengths will enable you to use more power while remaining eye-safe. Edit WebOptical astronomy, so called because it uses familiar ‘optical’ elements such as lenses and mirrors, and sometimes referred to as visible-light astronomy, is astronomy that is concerned with measuring visible light. This corresponds to electromagnetic waves with wavelengths of 380 to 750 nanometres.
