Viewing device with means for reducing the illumination intensity |
摘要 |
The invention concerns an optical viewing device which incorporates a spectral filter to partially reduce the intensity or wavelength(s) of light transmitted to a specific region of a specimen which may be a human eye. The reduction in light intensity or wavelength may be variable across the filter and may be accomplished in an intensity-dependent or a wavelength-dependent manner. |
