Zoom

A filter that transmits a specific wavelength in the UV range and cuts the visible range. It is used to select UV wavelength from a light emission or select a specific wavelength from multiwavelengths.

◦It is widely used in fluorescence imaging or selecion of only 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, or to cut off the brightness of the visible light and increase the sensibility of the UV light.

▶We can provide custom product not specifically mentioned on-line or in our catalog to your specifications, please contact our Sales Division with your specific requests.
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶The absorption wavelength range can not be used with high power laser and high energy pulsed laser.
▶There is no coating on both surfaces of the filter and there is a transmission loss of about 10%.
