uv bandpass filter ZWB1 ZWB2 ZWB3 10-300mm
Product Description
The Custom ZWB UV Bandpass Filter Glass is designed for ultraviolet optical applications where controlled UV transmission and reliable optical quality are required. Made from K9 glass or optical glass, it provides a stable material platform for UV lamps, optical instruments, inspection systems, fluorescence equipment, and industrial optical assemblies.
This UV bandpass filter is available in diameters from 10mm to 300mm, with customized sizes available for different installation structures. It is suitable for customers who need a custom optical filter for equipment development, UV system integration, optical testing, or OEM production.
The product features a transparent aperture of more than 98%, helping maintain usable optical area and practical transmission performance. For projects that require different appearance and optical quality levels, surface options include 60/40 and 40/20.
Precision processing is one of the key advantages of this ZWB filter. The filter supports 1/4 flatness, ±0.1 diameter tolerance, ±1% focal length tolerance, and ±0.01 center thickness tolerance. These specifications make it suitable for optical systems that require stable assembly, accurate positioning, and consistent component quality.
Coating can be made according to customer requirements. Depending on the final application, this UV bandpass filter can be used as a UV pass filter, ZWB optical glass filter, black glass UV filter, or customized optical component for ultraviolet systems.
For buyers looking for a custom UV bandpass filter with K9 glass or optical glass material, flexible diameter options, high transparent aperture, precision tolerance, and custom coating service, this ZWB UV filter provides a practical solution for professional optical and industrial projects.
