Diffusers for Laser Systems

Luminit Glass-on-Glass Light Shaping Diffusers are particularly applicable to laser, biomedical instrumentation and other high temperature/power applications, as well as UV applications requiring high transmission efficiency at UV wavelengths. Glass-on-Glass LSDs are available in three versions:

  1. Ultra-high Temperature/Power LSDs -- Pure glass diffusers up to 2”x2” in size that can diffuse from 0.5° to 15° while operating at temperatures up to 500°C with a laser damage threshold of 8J/cm².

  2. High-temperature LSD – A glass diffuser up to 2”x2” in size that can diffuse from 0.5° to 50° with operating temperatures up to 200°C.

  3. Hybrid glass LSD – This version can be made up to 20”x20” in size and with a wide range of angles from 1° to 80° circular as well as at many elliptical angles. It can also be produced on a wide range of optical glass substrates.

These Glass-on-Glass Light Shaping Diffusers offer transmission efficiency of 88 to 92% depending on angle in the visible light range. They are also available on silica UV53 substrate, which has transmission efficiency of 70% at 190nm.

Diffusers for Machine Vision Applications

Machine vision applications range from barcode scanners to sophisticated automated optical inspection systems to detect and measure defects on a wide variety of surfaces—from silicon wafers to champagne bottles—during and after their manufacture. Elliptical Light Shaping Diffusers supply the uniformity required for detailed line scan metrology applications. Following are some of these applications:

  • Bar Code Scanners

  • Wafer Inspection

  • Die Bonders

  • PCB Inspection

  • Photocopier scanners

  • Biomedical Applications

  • Ring Lights

Diffusers for Bio-Medical Instrumentation

Today’s medical instrumentation incorporates a variety of light from fluorescent sources, UV sources, lasers, and LEDs for applications from general lighting to laser surgery and everything in between. Following is a list of biomedical equipment that has utilized Luminit Light Shaping Diffusers:

  • Blood Analyzers

  • MRI Scanners

  • Bacteria ID Systems

  • Eye Screeners

  • X-ray Tomography Systems

  • Laser Cosmetic Surgery

  • Biological Imaging Systems

  • Teeth Whitening Systems

  • Cellulite Reduction Systems

  • Laser Eye Surgery

Diffusion for High-Brightness Projectors

The arc lamps and lasers used in today’s high-brightness projectors generate a lot of heat, which precludes the use of polymer-based diffusers. Luminit’s high-temperature Glass-on-Glass Light Shaping Diffusers can withstand heat up to 500°C and provide the same benefits as polymer-based LSDs within a narrower range of angles. They are also used in high power laser systems because they have high laser damage thresholds – 8J/cm². 

 

Diffusers for Light Guides and Light Pipes

Lumiitoffers a unique injection molded format of its Light Shaping Diffuser for Light Pipe and Light Guide applications.  Incorporating our precise micro-structure diffusers on one or both ends of the light pipe allows color mixing and beam angle control for more uniform and homogenized results. Available in both circular and elliptical beam profiles, Luminit light guide/pipe diffusers can be simulated before the mold is created to determine optimal beam patterns.

Features include:

  • Luminit’s patented holographically mastered nano-structures provide very high transmission (85 to 92%) for maximum light output

  • Choose from a number of symmetrical and asymmetrical beam angles to create a light pipe/guide that shapes the output beam

  • Light pipes/guides can be designed with mechanical tabs or clips for faster, lower-cost “snap-together” assembly

  • Non-yellowing material available for outdoor use as well as flame-retardant material to meet UL/CE flame retardant ratings

  • Simulation of diffusion/ray tracing available to predict optimal patterns
