Ordering Information
• Minimum order quantity: 10 units
Need fewer than 10? We understand that’s not always possible, get in touch and we’ll see what we can do.
• Looking for a complete laser module?
The CF3 is a bare component for OEM integration. If you need a ready-to-use module with electronics, software control, full connectivity, and no moving parts, you might want to take a look at our standard laser products:
→ ATLAS 1550 — C-band narrow linewidth tunable laser module
→ COMET — C-band swept source laser module
→ POLARIS — frequency-stabilized single-frequency laser module
