Replacement & Compatibility FAQ
Q: Can I replace the 2214-30SLQTC with a Melles Griot 05-LHP-151?
A: In most bench and laboratory setups, yes — both are 632.8 nm, 0.5 mW, single-mode He-Ne modules. Verify mechanical mounting and power supply compatibility before substitution.
Q: Is the 2214-30SLQTC still in production?
A: JDSU (now Viavi Solutions) has discontinued many legacy He-Ne laser lines. Konmask.com sources new-old-stock (NOS) and refurbished units. Contact us for current availability.
Q: What power supply does the 2214-30SLQTC require?
A: A regulated He-Ne power supply providing ~1,200–1,500 V starting voltage and ~3.5–5 mA ballast current. Do not operate without a proper ballast — this will damage the tube.
Q: Do you provide a warranty?
A: Yes. We offer a 90-day functional warranty on all units shipped. Extended warranty and service contracts available on request.
Q: Can you source multiple units for a production run?
A: Yes. Contact us with your BOM quantity and schedule. We can consolidate sourcing across multiple equivalent models if needed.
