850nm High Power VCSEL: Manufactured by ACE PHOTONICS for Precision Sensing Applications
At Ace Photonics Co., Ltd., we develop and fabricate high-performance semiconductor lasers with a strong focus on VCSEL technology. Our product portfolio covers the 750–1550 nm spectral range, and our website highlights capabilities across VCSEL die, VCSEL packages, VCSEL modules, and custom OEM solutions. For customers looking for a reliable manufacturer of 850nm High Power VCSEL products, this matters because supplier capability is often just as important as the laser specification itself.
We can provide 850nm-3mW single-mode VCSEL solutions for precision sensing and related optoelectronic applications. On our VCSEL Die page, we list 850nm 3mW VCSEL options in die, TO, customized, and non-magnetic packaging formats, giving customers more flexibility when moving from prototype design to product integration.
For sensing applications, the real value of a VCSEL is not only its output power. Beam quality, mode stability, wavelength control, package structure, and electrical efficiency all affect final system performance. Based on this product’s datasheet, our 850 nm single-mode device delivers 3 mW typical optical output under CW operation at 25°C, with single-mode emission centered at 850 nm, a symmetrical Gaussian beam profile, and stable divergence behavior in a TO46 package.
Why We Focus on 850nm High Power VCSEL Solutions
The 850 nm wavelength remains one of the most practical and commercially useful bands in VCSEL design. It is widely applicable in sensing systems and industrial optical platforms where stable near-infrared emission, mature process capability, and efficient integration are important. Our website also presents VCSEL technology as a strong fit for applications such as 3D sensing, LiDAR, medical instrumentation, optical communication networks, quantum sensing, and chip-scale quantum magnetometers, which reflects our broader development direction as a manufacturer.
From a manufacturer’s perspective, 850nm High Power VCSEL does not simply mean chasing a bigger output number. In many real customer projects, what matters more is delivering usable optical power with stable beam quality and a practical package. That is exactly why a 850nm-3mW Single-Mode VCSEL is a valuable offering in our product line.
What We Offer in This 850nm-3mW Single-Mode VCSEL
According to the datasheet, this device combines several features that are especially important for precision sensing:

TO46 package
For customers, these are not just numbers in a table. They describe a VCSEL that is designed to provide clean, stable, and practical optical output for real systems.
Why Single-Mode Output Matters to Our Customers
As a manufacturer, we know many customers are not only looking for an 850 nm emitter. They are looking for a source that is easier to design around.
That is where single-mode performance matters. In this product, the datasheet highlights single-mode emission, a symmetrical Gaussian beam profile, and stable divergence behavior. These features are especially helpful in systems where optical alignment, signal repeatability, and measurement quality depend on beam consistency.
A cleaner mode can reduce optical design complexity and help improve downstream performance. For customers working on high-precision sensing, that often matters more than simply choosing a laser with a larger but less controlled output.
Our Manufacturing Strength Behind the Product
At Ace Photonics, we position ourselves as more than a trading company. Our website states that we specialize in the development and fabrication of high-performance semiconductor lasers, especially VCSELs and VECSELs, and that our team brings 20+ years of VCSEL R&D experience. We also highlight technical strengths in vertical resonant cavity structure, current confinement, thermal management, polarization control, wavelength control, and array/integration technology.
This matters because customers sourcing a 850nm High Power VCSEL often want more than a standard part. They want a manufacturer that understands the physics, the chip design, the packaging, and the application environment. Our website also notes that we can customize epitaxial and device structure designs according to customer application requirements and support customized VCSEL design from wafer to packaging.
Why TO46 Packaging Still Matters
This product uses a TO46 package, and from a manufacturing and integration standpoint, that remains a practical choice for many sensing applications. Compared with bare die handling, TO-can packaging can make assembly easier, improve mechanical stability, and help customers shorten the path to system validation.
Our VCSEL Die page also makes it clear that we support multiple packaging directions, including die, TO, customized, and non-magnetic packaging. That gives customers more room to choose the format that best fits their optical design, thermal requirements, and system architecture.
Applications We See for This Product
According to the datasheet, this 850 nm single-mode VCSEL is suitable for:
Gas sensors
High-precision depth sensors
Industrial speed and distance sensors
These applications align well with our broader VCSEL development direction. On our website, we also discuss VCSEL use in sensing-heavy areas such as 3D sensing, quantum sensing, and medical instrumentation, showing that we build products with real application environments in mind.
From our perspective as a manufacturer, this is important. A good product is not defined only by its lab performance. It also needs to fit how customers actually build and deploy sensing systems.
Customization Is Part of Our Value
One of the practical strengths of this product is flexibility. The datasheet states that alternative wavelengths, chip dimensions, and emitter patterns are available on request. That means customers are not limited to a one-size-fits-all solution when their application needs something more specific.
This is consistent with how we position Ace Photonics overall. Our website emphasizes custom development based on application requirements and notes our experience supporting specialized environments and advanced packaging needs. For OEM and R&D customers, that makes a real difference when moving from evaluation to full project development.
Why Buyers Choose a Manufacturer-Led Partner
When a customer searches for 850nm High Power VCSEL or 850nm-3mW Single-Mode VCSEL, they are often asking two questions at the same time:
Can this product meet my system target?
Can this supplier actually support my project?
As a manufacturer, we believe both questions should be answered clearly. Our role is not only to provide a datasheet, but also to support customers with product understanding, packaging options, customization paths, and application-oriented development. That is why putting the manufacturer perspective up front is useful for procurement teams and engineering teams alike.
Final Thoughts
At Ace Photonics Co., Ltd., we see a 850nm-3mW Single-Mode VCSEL as more than a single product spec. It represents a practical solution for customers who need a stable, clean, and integration-friendly laser source for sensing applications.
With 3 mW typical CW output at 25°C, single-mode 850 nm emission, a symmetrical Gaussian beam profile, 25 dB typical SMSR, 15° typical divergence, and TO46 packaging, this product is well positioned for gas sensing, high-precision depth sensing, and industrial speed or distance sensing. Just as importantly, it is backed by our broader manufacturing and customization capability across VCSEL die and packaging solutions.
For customers looking for a manufacturer rather than just a reseller, that combination of product performance and engineering capability is what makes Ace Photonics relevant.
