專業UV Broad Bandpass Filter廠商

• High transmission in UV range

UV broad bandpass filter is designed to transmit the UV light effectively and blocks the light up to 2000nm. A colored glass U-340 is used as the substrate. The interference film is coated on the U-340 to achieve both the low ripple in passband and the rejection of red leak simultaneously. Standard sizes are 25mm diameter and 50mm x 50mm. Custom size is available on request.
