VCSEL - standard and customized solutions
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.

VCSEL technology
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.
Your requirement, our solution
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 close this gap and turn challenges into competitive advantages.
