Whether in industrial manufacturing, medical technology or the automotive sector – lasers enable precise distance measurements, high-accuracy material processing, and also open up new possibilities in medical applications.

From June 24 to 27, 2025, ams OSRAM will showcase its latest laser innovations at the Laser World of Photonics trade fair in Munich, at booth 332 in hall A2.

Optical sensing for robotics and automation
Lasers play a key role in high-precision distance measurement and object detection in both robotics and automation. VCSEL-based (Vertical-Cavity Surface-Emitting Laser) products such as the BIDOS® P3435 Q BELAGO 1.2 Dot Projector and the BIDOS® P2433 Q V105Q121A 850 Flood Illuminator, are used in 3D sensing. The dot projector, operating at a wavelength of 940 nanometers, generates a precise dot pattern that is captured by a near-infrared (NIR) image sensor and enables the calculation of a 3D map — an essential element in technologies such as Active Stereo Vision (ASV) and Structured Light (SL). These 3D maps provide robots with high-resolution spatial awareness of their environment. The 850-nanometer Flood Illuminator, in turn, enables uniform illumination to deliver accurate distance measurements in Time-of-Flight (ToF) applications — a key requirement in Automated Guided Vehicles (AGVs).

Along with laser sources, ams OSRAM also provides a range of compatible sensors, such as image sensors for ASV and SL camera systems, and direct Time-of-Flight (dToF) sensor modules that integrate one VCSEL and several photodiodes in one package. In addition to smart sensors, the company offers a diverse portfolio of emitters and photodetectors, giving developers greater flexibility in system design.

The versatility of laser diodes: cyan, green, and blue in action
Cyan laser diodes with a wavelength of 488 nanometers play a key role in medical diagnostics, as they effectively stimulate fluorescent dyes. This technology enables the precise analysis of biological samples, such as in DNA sequencing. The PLT5 488HB_EP cyan laser diode, delivering an output power of 300 milliwatts, is up to five times brighter than its predecessors, significantly increasing both its efficiency and range of applications. With precise and stable wavelength control of +/- 2 nanometers, this diode enhances the visibility of fine details in fluorescence microscopy, simplifying the study of cellular structures. In addition, it expands the color spectrum available for stage or stadium lighting.

Green laser diodes are considered to be particularly powerful when it comes to applications requiring high visual perception and precise light guidance. Their wavelength lies within the most sensitive range of the human visual system, making them ideal for measurement tasks under daylight conditions or in bright ambient environments. In construction surveying, they enable precise laser leveling and accurate measurements. In distance measurement and target acquisition, such as barcode scanning in logistics, green lasers also deliver fast and accurate results. In the entertainment and projection industries, they create brilliant and attention-grabbing lighting effects — ideal for clubs, stages, and concerts. The PLT5 520HB_P green laser diode, with its 520-nanometer wavelength, stands out due to its compact form factor and 130 milliwatts of optical output — up to 18 percent more than its predecessor — as well as its increased efficiency for these high-performance applications.

Blue lasers offer versatile capabilities across a range of applications. Thanks to their conversion capabilities, blue laser diodes can generate high-power white light as well as a wide range of other colors, including red, green, and orange, significantly expanding the scope of this technology's applications. The PLPT9 450LC_E blue laser diode, operating at 455 nanometers, combines a compact design with high optical power of 5.5 watts. Its high power density makes it ideal for microscopy, large-scale projections, and material processing such as laser engraving. Blue lasers are also popular in metrology and stage lighting, where they offer a strong blue beam with high optical performance.

In addition to laser technology, ams OSRAM is also presenting the latest generation of its infrared LEDs OSLON® Black, SFH 4715B and SFH 4716B. Featuring reliable and efficient IR:6 technology on a 1 mm² chip, these infrared LEDs deliver a typical radiant power output of 1050 milliwatts and up to 26 percent more brightness compared to their predecessors. This performance boost enhances the capabilities of optical systems, making the OSLON® Black series ideal for a wide range of industrial automation and safety applications — in both industrial and consumer environments.

Laser technologies in detail: infrared and color lasers with VCSEL and EEL
The broad laser technology portfolio from ams OSRAM is key to the performance and flexibility of the products showcased at the Laser World of Photonics in Munich.

Lasers from ams OSRAM cover a wide range of wavelengths, spanning from the visible light spectrum (400 to 700 nanometers) to the light spectrum invisible to the human eye (above 700 nanometers). This diversity enables the design of high-performance solutions for a variety of applications.

The ams OSRAM laser portfolio is built on two core technologies: VCSEL and EEL (Edge-Emitting Laser). VCSELs emit light perpendicular to the surface of the semiconductor and are particularly suitable for 3D sensing in mobile devices, industrial systems, and automotive applications. EELs emit light along the edge of the semiconductor and are ideal for applications requiring high intensity or continuous operation — such as material processing, lighting, or LiDAR systems.

From robotics to medical technology, the laser portfolio from ams OSRAM offers precise and efficient solutions for complex challenges. Continuous development and innovation in laser technology secure the company’s leading position in this important technology field.

ams OSRAM holds over 2,000 active patent assets in the field of laser diodes worldwide, maintaining an unrivaled leadership position within this industry*.
