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.


Image directing film for aviation 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.

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 Heads-up Displays 

Luminit diffusers are actively engaged in commercial and aerospace display markets and include such ground-breaking products as Direction Turning Film designed to enhance the viewing angle, brightness and efficiency of displays used in avionics and in consumer electronics. Luminit is also an industry leader in advanced holographic technologies for Heads-Up Displays (HUDs) and Head Mounted Displays (HMDs). Luminit also supplies its Light Shaping Diffusers in a variety of angles on non-birefringent and other specialty substrates for use in 3D systems utilized for computer graphics, signage and gaming applications. Rolls or rigid substrates for high volume operations or the film can be cut to size.
