BIXBY OPTICAL FAQ

BIXBY'S HIGH-HIDING DIFFUSERS

What is a high-hiding diffuser?

High-hiding diffusers are designed to hide LED hotpots to generate a more uniform appearance. This is often accomplished through fillers that create a more opaque diffuser to mask the view of LED hotspots, however, this can slightly limit the lighting output. Bixby’s diffuser technology does not use fillers or laminates. The high-hiding ability derives from the multi-faceted surface which masks the hotspots while allowing full light transmittance.   

What diffusion angles are available?

Our standard product line angles include 80° circular, 60° circular, 20° circular, 10° circular, and an 80°x 50° elliptical output. We can also customize our diffusers to nearly any desired angle upon request thanks to our patented facet-design technology.

What sizes of LED light diffusers are available?

Depending on the customer’s unique design characteristics, Bixby’s cast extrusion lines can produce both sheet and roll goods at a range of thicknesses and widths. Thicker sheet constructions can be die-cut to accommodate custom dimensions and thinner designs can be slit internally to a specified width. Contact one of our technical experts today to learn more about which of our capabilities matches best with your design criteria.

Are you able to manufacture custom angles outside of your listed products?

Yes, Bixby’s facet design technology can be tailored directly to your needs to match almost any photometric output. This includes circular, elliptical, top-hat, and asymmetric distributions as well as custom shapes depending on the characteristics of the incoming light source.

How can I cut Bixby’s diffuser? Do I need special tools?

Depending on the diffuser material and desired thickness, cutting Bixby’s diffusers is fairly simple. Thick constructions can be die-cut and thinner constructions can be cut easily with scissors or shears.

Are Bixby diffusers waterproof?

Yes, materials such as polycarbonate, acrylic, and polyester are resistant to water.

Can Bixby LED diffuser micro facet patterns flake or delaminate over time?

No. Bixby’s light-shaping elements are incorporated directly into the bulk sheet or film material. This serves to improve durability in rigorous service environments subject to mechanical stress, UV radiation, humidity, and exposure to chemicals or cleaning products.

Are Bixby diffusers RoHS compliant?

Bixby extrudes one of the broadest portfolios of materials in the extrusion industry. We work in collaboration with our strong network of supplier relationships to implement materials that meet our customer’s needs and provide the proper certifications.
