¡ñ High transmission in UV range and visible range has been reflected to reduce the image noise because of VIS light.
¡ñ Coatings made on UV fused silica for the heat-resistance and steady work. |

|
| This type of UV filter, also called UV Cold Mirror, highly transmit the UV light but reflect the visible light. No special treatment is made, so parts of NIR light allow transmitting. With heat-resistance fused silica substrate, it is perfect used for equipments like UV silk-screen device, UV illuminating equipment, UV welding equipments and other equipments working with only UV light. |
