功能

• A filter that transmits specific wavelengths in the ultraviolet region and cuts the visible region.
• It can be used to extract ultraviolet light from white light or to extract necessary ultraviolet light from multiple wavelengths of light.
• Use this function when you want to irradiate ultraviolet light but not visible light for fluorescence observation.
• UTVAF-36U can be used to extract the i-line (365 nm) of a mercury lamp.
• By inserting a filter into the detector in the short wavelength range, you can block high-intensity visible light and increase sensitivity in the ultraviolet wavelength range.
• A narrowband bandpass filter (VPF) is also available.
• A high transmittance interference filter (YIF) is also available.
• * Cannot be used for high-power laser or high-energy pulse laser in the absorption wavelength range.
• * Anti-reflection coat is not applied on both sides.
• * Reflected light from the front and back causes a transmittance loss of about 10%.
