  • diffusers for high powered lasers

  • 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 Light Shaping Diffusers are available in three versions:

    1. Ultra-high Temperature/Power Light Shaping Diffusers®-- 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 diffuser – 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 Light Shaping Diffuser®– 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.

  • diffuser for bar code scanner

  • 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

  • laser diffuser for bio medical equipment

  • 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

  • diffuser to reduce speckle on a laser projector

  • 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 Light Shaping Diffusers® 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

  • Diffusers for Light Guides and Light Pipes

    Luminit offers a unique injection molded format of its Light Shaping Diffuser® for light guide optics. 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

 round tip display film

Round Tip Display Film

Luminit Round-Tip Display (RTD) Film is designed to increase the brightness of displays by making use of  refracted and reflected light to recycle otherwise wasted light and direct more light toward the viewer. The RTD film can provide a brightness gain of 30% to 40% in a display. The round tips are more rugged than sharp tip prisms which can break off in use causing contamination in the display.
direction turning film for displays

Direction Turning Film

Direction Turning Film (DTF) is a transparent optical component that takes the image created by a flat panel display and directs it by 20° up, down, left or right to attain an optimal angle for the viewer. Incorporating DTF into a display is easy. It can be used either within the display under the LCD or on top of the LCD in the display. DTF may also be incorporated in double-sided film with the DTF on one side and a Luminit Light Shaping Diffuser® or Round Tip Prism brightness enhancer. Direction Turning Film is an effective replacement for 3M's Vikuiti™ Image Directing Film II (IDF II).

 

LCD display brightening film

 

LCD Display Brightness Film

Our Display Brightness Film (DBF) is a light management film that increases the brightness of LCD screens. Used in automotive touchscreens, avionics displays, smartphones and other portable devices, this display enhancing film has a prismatic structure and utilizes the principle of refraction and total internal reflection to redirect light. The result is brighter and more efficient displays. 

 

diffusers for smartphones and IR sensors

Diffusers for IR Sensors 

Luminit’s IR (Infrared) Direction Turning Film (DTF) is highly effective when used with narrow-band IR LED sensor applications such as in consumer electronics. An asymmetrical, prismatic film mastered using grayscale lithography, IR DTF film imparts a 10° shift in the angle of an IR 810nm LED light source and is specifically designed to work with Osram’s IR OSLUX SFH 4780S LED. IR DTF helps engineers and product designers overcome the challenge of having the LED and the sensor located next to each other. The DTF directs the light more accurately toward the target (e.g., the eye) and back to the sensor to collect data.
