Description
Product Introduction & Engineering Value
The JDS Uniphase 2114B-30SLT is a dedicated laser power supply associated with 30 mW argon-laser systems used in KLA-Tencor semiconductor inspection platforms. Service documentation identifies it on Surfscan 6200, 6220, 6400, and 6420, as well as SP1-family equipment.
This is not a generic AC/DC replacement. The supply is part of a tightly matched laser subsystem, so output characteristics, interlocks, cabling, and equipment compatibility need to be checked before substitution. Repair and replacement services specifically list the 2114B-30SLT as a laser power-supply assembly.

Field Application & the “Trench” Experience
A typical failure scenario would occur on an older wafer-inspection system where the laser no longer reaches its required operating condition. The machine may report a laser fault, fail initialization, or produce unstable optical output. The maintenance engineer traces the fault to the dedicated power supply and finds the installed assembly marked 2114B-30SLT.
The important lesson is simple: do not replace the supply merely because its input voltage matches another industrial power supply. The laser supply is part of the optical subsystem. Startup behavior, current regulation, protection circuits, interlocks, and output characteristics matter.
Typical applications include:
- KLA-Tencor Surfscan 6200/6220 laser inspection systems
- KLA-Tencor Surfscan 6400/6420 platforms
- SP1-family semiconductor wafer inspection equipment
The 2114B-30SLT is specifically documented in service references for these types of inspection platforms.
Transparency SOP: QA & Testing
For New Surplus or Refurbished inventory, the useful QA sequence is:
- Part-number verification — Confirm the label reads 2114B-30SLT or the documented alternate 2114B30SLT.
- Electrical inspection — Examine input terminals, connectors, wiring, cooling components, and enclosure condition.
- Controlled power-up — Apply the correct AC input under appropriate laboratory/service conditions.
- Output evaluation — Test the supply using the manufacturer’s or qualified service procedure rather than connecting an unknown replacement directly to a production laser.
- System compatibility check — Verify the target KLA/JDSU equipment model and laser assembly before shipment.
- Final condition report — Record whether the unit is New Surplus, Refurbished, Repaired, or Tested Used.
Specialized service companies currently advertise both tested and refurbished versions of the 2114B-30SLT, with repair services also available.
The Veteran’s Tech Trap Guide
⚠️ Trap #1 — Confusing the power supply with the laser itself.
The 2114B-30SLT is the laser power supply, not the complete argon laser assembly. Replacement documentation should identify both components separately.
⚠️ Trap #2 — Ignoring the machine model.
The same part number can appear across related inspection platforms, but that does not automatically make every connector, firmware/configuration, or installation arrangement identical.
PRO TIP: Before removing the failed unit, photograph the nameplate and all connectors. Record the KLA system model and the laser assembly part number. This makes cross-checking a replacement much safer.
⚠️ Trap #3 — Treating a 30 mW laser supply as an ordinary bench power supply.
This assembly is designed for a specialized laser system. Improper testing or substitution can damage the laser or create a hazardous operating condition. Use the appropriate service procedure and laser-safety controls.
Dynamic FAQ
Q: What is JDS Uniphase 2114B-30SLT?
It is a specialized 30 mW argon-laser power supply used in semiconductor inspection equipment.
Q: What input power does the 2114B-30SLT require?
A published equipment reference specifies AC 200–220/230–240 V, 13 A, 50/60 Hz.
Q: Which equipment uses this power supply?
Service references identify it with KLA-Tencor Surfscan 6200, 6220, 6400, and 6420 systems and selected SP1-family systems.
Q: Is 2114B30SLT the same part number?
Yes. 2114B30SLT is listed as an alternate formatting of 2114B-30SLT by service and parts references.
Q: Can I use a generic 30 mW laser power supply as a replacement?
No—not without engineering validation. Output characteristics, interfaces, protection circuitry, interlocks, and the target laser assembly must all be compatible.
Q: What should I verify when purchasing New Surplus 2114B-30SLT?
Confirm the exact part number, electrical rating, physical condition, target KLA/JDSU system, and whether the seller is offering genuinely unused surplus or a refurbished/tested unit. Warranty terms should also be stated separately; service providers currently advertise 12-month coverage on some repaired/refurbished units.
