A filter that transmit a specific wavelength at the UV range and cut the visible range.
It is used to select UV wavelength from a light emission or select a specific wavelength from multiwavelength.
It is widely used in fluorescence imaging or select only a UV exposure from a visible light.
UTVAF-36U is used for selecting the emitted light of the I line (365nm).
Use the filter in a short wavelength detector and cut off the brightness of the visible light can increase the sensibility of the UV light.
