Laser Diodes
Surface-emitting VCSEL
IMM Photonics offers high-performance VCSEL solutions optimized for demanding applications in oxygen sensor technology and modern high-speed telecommunications. The VCSEL laser diodes are available in wavelengths of 850 nm and 760 nm and deliver stable output powers from 0.5 mW to 1.5 mW. They feature a round Gaussian beam, fixed polarization alignment (polarization-locked), and excellent spectral stability.
Precise beam quality in reliable TO packages
VCSEL variants with or without integrated photodiodes are available for maximum precision. This enables real-time optical feedback for reliable power control and advanced sensor technologies. The hermetically sealed TO housings, the precise alignment of the chips, and the particularly stable emission guarantee consistent performance — even under harsh environmental conditions.
Optimized for demanding applications
Our VCSEL laser diodes are used in optical sensor technology, distance and speed measurement (ToF), industrial automation, life science analysis, and oxygen measurement (O₂ sensor technology), among other areas. Thanks to their compact design and high efficiency, IMM Photonics VCSELs are the ideal laser light source for precise, durable, and cost-efficient systems.
Customized VCSEL modules – from concept to series production
In addition to our standard solutions, we offer customized VCSEL modules with rapid prototyping and scalable production. As an experienced European VCSEL manufacturer, we combine optical, mechanical, and electronic expertise under one roof. This enables us to create customized, market-ready solutions that meet the highest technical requirements.

What are the advantages of using VCSEL lasers?
Vertical-cavity surface-emitting lasers (VCSELs) offer compact design, high energy efficiency, and excellent beam quality. Unlike edge-emitting lasers, VCSELs emit light perpendicular to the wafer surface, enabling scalable series production and superior optical performance. Their symmetrical Gaussian profile and low divergence make them indispensable for precise sensing, LiDAR applications, and high-speed data transmission.
How do VCSEL modules from IMM Photonics meet your specific application requirements?
Whether optical encoders, sensors, LiDAR systems, oxygen measurement, or short-range data links – you need light sources that are fast, stable, and easy to integrate. Bandwidth for high-speed communication, spectral stability for accurate measurements, and robust housings for demanding environments are crucial.
IMM Photonics’ VCSEL modules are precisely designed to meet these requirements. They combine high-performance VCSEL technology with application-optimized design, high vertical integration, and industry-standard packaging. In this way, they bridge the gap between technological capability and practical feasibility—and transform technical challenges into measurable competitive advantages.
