Osram Infrared Mini midled can produce a narrow angle and strong infrared beam

Osram Photoelectric Semiconductor Infrared Mini midled height is only 0.9mm, but this small device can produce a narrow angle and strong infrared beam. Using its radiation intensity of 60 milliwatts per sphere (Steradian, MW/SR) per 100 ma (MA), performance can easily outperform other equivalent devices. The surface is then understated, and is particularly suited to the limited space used as proximity sensors and light filters.

In many sensor applications, the important factor is not only the light power of the transmitter, but also the light in the narrow high power beam that is wide shot or concentrated. The Half-width value illustrates this feature. The intensity of radiation (in per spherical watt) refers to the optical power of the stereo angle, defined as the intensity of the beam emitted.

The great advantage of the new Mini midled is that its half angle is 17°, which produces a narrow beam and has a MW/SR radiation intensity at 100mA. This performance is achieved because the product utilizes a metal-treated reflector integrated into the device to concentrate light. This new LED, although very small in size, has only 2.3 x 1.95 x 0.9 mm, but its output power is quite high.

The Mini midled is the second surface of the Osram photoelectric semiconductor in the form of a three-dimensional circuit board forming (molded interconnected Device, abbreviated MID). This new packaging technology allows OSRAM semiconductors to reduce the height of the new infrared launcher to less than a millimeter, but ensures that it can be processed in a generic manner.

Small but powerful infrared emitting diodes with a wavelength of 850nm, such as the slim narrow beam Mini midled, can be a great boon for space-constrained applications that require high emission intensity. The usual applications include a light shield, smart phone, and an optical touch screen.

No mutual interference noise

Osram Photoelectric Semiconductor marketing manager Bianka Schnabel has a deep expectation for the new Mini Launcher: "This slim mini midled is particularly suitable for use in smart phones and similar devices as proximity sensors because it takes up a small amount of space but provides powerful power." Because of its exquisite design, it can also be the first mate to reduce the noise of light interference, do not need to use the light shielding, so that designers can be more relaxed. ”

The proximity sensor combines the transmitter with the detector, which illuminates the approaching object, and the detector receives the light reflected from the object. In order to function properly, it is important that the light emitted from the transmitter should not be sent directly to the detector (this is known as the noise of mutual interference). This behavior usually occurs when the device is not fitted with a metallized reflector. But if there is a Mini midled, there is no need to use masking, the overall design will be simpler.

The surface without metallization is black, so the Mini midled can be adhered to on the smartphone lid without abrupt appearance.
