Because it has a high transmittance in the deep ultraviolet range, it can eliminate light unevenness and achieve uniform light.
By applying a special treatment to the surface, a fine structure is created, allowing light emitted from the light source to be diffused without waste, thereby eliminating light unevenness and achieving uniform illumination. Since synthetic quartz glass is used as the material, it is compatible with deep ultraviolet wavelengths, has a high transmittance, and is extremely resistant to thermal effects, making it suitable for a wide range of applications beyond lighting. 【Features】 - Forms fine unevenness on the surface of quartz glass to diffuse transmitted light - High light transmittance (from deep ultraviolet to infrared) - Excellent heat resistance 【Usage Scenarios】 - Surface sterilization, uniform lighting, analysis/testing equipment, medical applications, image processing equipment, light source devices, etc.
"Eliminates uneven UV light irradiation" Controls the spread angle in the ultraviolet range (200nm and above) for diffusion! Excellent transmittance even in high-temperature environments 'UV Diffusion Plate: UFD'
The "UFD" is a UV diffusion plate that can be used in the ultraviolet range. It can eliminate uneven illumination from UV (200nm and above) light sources. Due to the structure formed on the surface of synthetic quartz, it distributes light at angles of 5°, 15°, and 25° (FWHM) when parallel light is incident, efficiently spreading the illumination over a specified range. Additionally, you can use it while maintaining the weather resistance of synthetic quartz. 【Features】 ■ Usable in the UV range ■ Quartz-based with excellent heat resistance ■ Compatible with sizes of 150mm x 150mm (custom order) (larger sizes available upon consultation) ■ Diffusion angles at 240nm: 5°, 15°, 25° (FWHM) *Based on our simulations *For more details, please refer to the PDF document or feel free to contact us.

It is widely used as a light source for line CCD in the inspection of liquid crystal glass substrates!
For example, when arranging multiple LED light sources in a one-dimensional line for line CCD lighting, it is obvious that diffusing them in a circular manner is inefficient. By diffusing the light in an elliptical shape, we achieve efficient illumination. In this column, we introduce an example using a red laser marker as the light source, employing a super-elliptical diffusion plate that diffuses at 60 degrees on the horizontal axis and only 1 degree on the vertical axis to create a line light source, along with accompanying photos. We hope you will take a moment to read it. [Contents] ■ Lens diffusion plate that diffuses in an elliptical shape *For more details, please refer to the PDF document or feel free to contact us.
