ZWB3 filter UG3 UV bandpass glass for 253.7nm 254nm 10-300mm
Product Description
The Custom ZWB3 Filter for UV Devices is an optical glass component designed for ultraviolet devices, UV lamps, inspection tools, detection systems, and OEM optical projects. It is made of K9 glass or optical glass and can be applied when a customized UV filtering optical component is needed.
This ZWB3 filter is provided with the available diameter from 10mm to 300mm. Custom sizes are also possible to produce according to customer’s drawings or project requirements. It is suitable for UV devices manufacturers, optical system integrators, laboratory equipment suppliers, and industrial inspection solutions providers.
For optical assembly, the ZWB3 filter is made with dimension tolerance control. Its diameter tolerance is ±0.1, its focal length tolerance is ±1%, and its center thickness tolerance is ±0.01. The 1/4 flatness ensures the stable installation in optical housings, UV modules, and custom mechanical constructions.
Its transparent aperture is more than 98%, ensuring the large usable optical area for UV filtering. Its surface quality can be supplied in 60/40 and 40/20 according to project requirements. These surface quality options allow the customers to find the right balance between optical quality, appearance, and production cost.
Coating can be customized according to the customer’s requirements. According to its final design, the ZWB3 filter can be used as a UV pass filter, black optical glass filter, UV bandpass filter, or customized optical glass component for ultraviolet systems.
For the buyers requiring a custom ZWB3 filter with K9 glass or optical glass material, flexible diameter option, precision tolerance control, high transparent aperture, and coating customization, this product provides a good solution for UV equipment production and optical system integration.
