Agilent HP 81680A Tunable Light Source (TLS) repair and calibration

The Agilent - HP 81680A Tunable Laser has been discontinued for a long time. This model just like the 81640A, offer two outputs so High Output port and Low SSE port.  Over the years, Simbol developped a solid expertise at this unit repair. We revive over 95% of 81680A and 81682A TLS sent to us if original Agilent seals are intact. We repair these units at fixed rate and it is extremely difficult to state what repair is needed based on alarm on display.  Best is that you send us an email with a problem description and we will give you some feedback on the reported problem and give you an RMA with estimated turn arond time.  We repair at least one Agilent - HP TLS per month. If you need to buy another unit, see our selection of TLS at
