To distribute light uniformly, optical diffusers are utilized in a range of applications. Using optical diffusers can help you hide a light source or get rid of the image of its filament, increase the angular range over which a signal transmitted through the air can be detected, uniformize the appearance of a viewing screen, and spread light from a source into a specific angle, among other things.
Alfa Chemistry creates cost-effective, premium optical diffusers specifically for each customer. Our optical design team makes use of the knowledge to produce products for our customers that perform at the highest level. Our optical diffusers are available in a range of shapes and package arrangements, and they are produced to sub-micron tolerances.
Our Customization Capabilities
Alfa Chemistry can provide our clients with various diffuser kinds to suit their needs. These consist of:
- Newton-resistant glass with a slightly etched surface: It deforms sufficiently when put on another optical plane to avoid interference.
- Flash opal diffuser: It produces light with a Lambert distribution-like brightness that is not influenced by the angle of observation.
- Ground glass diffusers: Customers have the choice between UV fused silica from Alfa Chemistry (which ranges in wavelength from 175 nm to 2200 nm depending on the thickness of the substrate) and borosilicate (which has one side that diffuses to a level that controls the scattering angle) (310 nm to 2700 nm).
- Plastic screen diffusers: This is a lighter, more adaptable, and more affordable alternative. For the purpose of answering specific, tailored queries, these can be carved into more intricate shapes.
Each type of diffuser has unique benefits and restrictions. In addition, we provide one-of-a-kind diffusers for specialized uses not covered by our catalog. Contact our specialists if you need assistance selecting a diffuser for your application.

Custom UV Ground Glass Diffusers
Custom UV ground glass diffusers can disperse light up to a 10° angle. Focusing and improving uniform illumination in UV lighting systems are their two main applications. Custom UV-grade fused silica hair glass diffusers are available that can operate in UV down to 175nm. Custom UV-grade fused silica frit diffusers can be made in any thickness and enormous diameters up to 300 mm in diameter. In order to satisfy your unique requirements for a custom UV grade diffuser, they can be created in any custom size and shape.
