This article takes a look at Edmund Optics’ latest move to expand its spectroscopy lineup. They’ve added Fiber-Coupled Gas Cells and Gas Flow Cells from Wavelength References.
These reference tools, which are NIST-traceable, aim to make wavelength calibration easier for demanding spectroscopy and laser applications. They’re also available quickly and fit right into most optical setups.
Advancing Spectroscopy With Robust Gas Cell Calibration
Wavelength calibration is pretty much the backbone of any spectroscopy or laser measurement system. Even a small drift in wavelength can throw off results or mess with long-term stability studies.
Edmund Optics saw this gap and added Fiber-Coupled Gas Cells and Gas Flow Cells from Wavelength References to their product line. These devices give users a straightforward, NIST-traceable way to keep wavelength accuracy on point across all sorts of optical platforms.
NIST-Traceable Calibration for Fast, Repeatable Results
The new gas cells use NIST-traceable reference standards. That means the spectral lines you see are locked to internationally accepted wavelength values.
This matters for regulatory and quality assurance reasons—and honestly, it just makes data comparison between labs or over time way more reliable.
Since the spectral features are stable and well known, users can:
Fiber-Coupled vs. Flow Cells: Flexible Options for Different Systems
No two optical systems are exactly alike, so calibration hardware needs to keep up with different setups. That’s why these new gas cells come in both fiber-based and flow-based versions.
Fiber-Coupled Gas Cells: Compact, Plug-and-Play Stability
Fiber-Coupled Gas Cells use sealed reference gases to produce predictable, stable calibration peaks. Their compact, plug-and-play design means you can drop them into fiber-based spectrometers and laser systems without a bunch of rework.
Some highlights:
This setup is great if you want simplicity and reliability. Once it’s in, you can pretty much leave it as a permanent reference and cut down on downtime and recalibration.
Gas Flow Cells: Continuous Gas Movement and Greater Flexibility
If you need more flexibility for calibration or measurement, Gas Flow Cells let you move gas continuously through the cell. That allows you to use different gases, mixtures, or pressures—super handy for more configurable systems.
Flow Cells work well when:
You can pair the continuous flow design with existing gas handling setups. This makes these cells a solid fit for industrial, semiconductor, or R&D environments where things change a lot.
Built for Laboratory, Production, and R&D Demands
Calibration tools often end up in places where equipment gets reconfigured, moved, or used around the clock. The new gas cells are built to handle all that.
Rugged Housings and Reinforced Interfaces
Both Fiber-Coupled Gas Cells and Gas Flow Cells come with rugged housings and reinforced interfaces that stand up to repeated use. Mechanical strength matters here—it affects beam alignment, coupling efficiency, and long-term stability.
Configuration choices include:
Global Access: In-Stock Availability and Technical Support
It’s not just about the tech specs—access and support can make or break a calibration strategy. Edmund Optics leans on its global infrastructure to make sure you can get these gas cells and the help you need, wherever you are.
Marketplace Scale Backed by Engineering Expertise
Edmund Optics makes Fiber-Coupled Gas Cells and Gas Flow Cells from Wavelength References available for immediate purchase. They ship fast, worldwide, right from the marketplace.
Their catalog doesn’t stop there. You’ll find over 34,000 in-stock optical products—lenses, filters, imaging systems, and more precision components than you might expect.
Some extra perks:
If you need more than just off-the-shelf parts, Edmund Optics’ Advanced Manufacturing division can help. They handle custom and volume production of precision optical and imaging components.
Multiple design centers and factories around the world back their custom work. You can build out complete, calibrated optical systems—prototype to full-scale—using their consistent ecosystem and support team.
