UV Diffusion Plate "UFD"

UV Diffusion Plate "UFD"

"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.

[Development Product] Reflective Diffuser Plate 'R-LSD'

[Development Product] Reflective Diffuser Plate 'R-LSD'

For FA use and inspection lighting, screens, etc.! Diffusion effects can be expected without directly exposing the light source.

"R-LSD" is a reflective diffusion plate that utilizes the characteristics of a lens diffusion plate (LSD) to diffuse reflected light with a targeted light distribution. It is suitable for situations where transmissive diffusion plates cannot be used, for lighting where the light source needs to be concealed, and for screen-like applications. It can be expected to reduce laser speckle and provide a diffusion effect without directly exposing the light source. 【Features】 ■ Lens diffusion plate: Utilizes the characteristics of LSD ■ Diffuses light with a targeted distribution of reflected light ■ Sample provision consultations available ■ Reduces laser speckle and can be expected to provide a diffusion effect without directly exposing the light source *For more details, please refer to the related link page or feel free to contact us.

Elimination of lighting unevenness by the lens function diffusion plate of the LED.

Elimination of lighting unevenness by the lens function diffusion plate of the LED.

Irradiation within a certain range! Achieving efficient lighting with minimal energy loss.

"Lens Diffuser: LSD (Light Shaping Diffusers)" transfers fine holographic irregularities onto the surface of a thin film, which diffuses incident light at a constant angle due to its refractive properties, utilizing the interference patterns of the hologram as a micro-lens array. In this column, we will introduce a method for eliminating lighting unevenness using lens function diffusers, which effectively addresses the shortcomings of LED lighting devices, such as "color aberration caused by lenses." Please take a moment to read it. [Contents] ■ Elimination of lighting unevenness using lens function diffusers *For more details, please refer to the PDF document or feel free to contact us.

Function and Features of the LED Lens Diffuser

Function and Features of the LED Lens Diffuser

There are many benefits such as reducing the number of LEDs, saving power, miniaturization, and lowering installation and running costs!

This column discusses the functions and features of lens diffusion plates. By using lens diffusion plates, there are numerous benefits such as the adoption of low-output LED chips, reduction in the number of LEDs, energy savings, miniaturization, and lower initial and running costs. We introduce this with photos showing lens diffusion plates that diffuse light at 5 degrees in front of light sources with uneven illumination. Please take a moment to read it.

LED oval diffusion lens diffuser

LED oval diffusion lens diffuser

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.

Lambertian diffuser

Lambertian diffuser

A completely diffusing glass diffusion plate! The light that comes out shows almost the same light distribution.

The "Lamberts Diffuser" is a product that creates uniform lighting. Due to the internal structure of the glass treated by heat, it scatters light, achieving complete diffuse light despite having a low transmittance. Additionally, it has flat spectral transmittance characteristics from the visible range to the near-infrared range, and has a proven track record in applications such as reducing speckle in laser light and screen use. 【Features】 ■ Almost completely diffuse surface for both reflection and transmission ■ Compatible with Φ100mm (custom order) (other sizes available upon consultation) ■ Good heat resistance due to glass base ■ Diffusion angle of 115° (FWHM) at 632.8nm (measured by our company) *For details, please refer to the catalog available for download below "PDF Download."
