Colored Glass Filters
COLORED GLASS FILTERS
UV filter (UV series)
UV filters are longpass filters that cut off the wavelength light shorter than a specific wavelength as much as possible, while transmitting the longer wavelength light as much as possible, within UV wavelength range.
Application: Medical
