Colored Glass Filters
COLORED GLASS FILTERS
Multiband Calibration Filters (V, HY)
V10 and V11 contain neodymium, and HY1, holmium. All three exhibit outstanding absorption at specific wavelengths.
The filters are used for wavelength calibration and V10 as a dual-color-type filter.
Application: Wavelength calibration
Images: HY1 / V11
