Plasma Light Sources with Liquid Light Guide Chapter 2: Safety Safety Chapter 2 The lamp comes with a switching power supply compatible with voltages from 100 to 240 VAC. There is no need to change the fuse when selecting your regional voltage. If the user needs to change the fuse located below the AC plug on the back of the unit, see section 6.1.
Description Chapter 3 3.1. Overview Thorlabs’ HPLS300 series plasma light sources combine the best features of solid-state electronics and full spectrum plasma emitters. The Luxim ® Light Emitting Plasma (LEP)™ bulb module uses a ceramic resonant cavity to efficiently couple power from a solid-state power amplifier into a high-intensity discharge vessel. This technique results in the long life of the bulb module (6000 hours typical operating time before the optical power output at given driving current drops to 50% of the initial intensity) and produces a complete color spectrum.
Typical Output Spectrum of the HPLS343/345 The HPLS343 and HPLS345 light sources provide a full color spectrum from 350 nm to 800 nm. Figure 2 shows a typical output spectrum of an HPLS343 and HPLS345 light source, measured at the output tip of the liquid light guide.

The light source also has four slots, located at the four bottom corners. As shown in Figure 4, by using Thorlabs table clamp CL6 or CL8, together with one of Thorlabs' baseplates, one can securely mount the plasma light source onto the surface of an optical table or breadboard with 1/4"-20 or M6 threaded mounting holes.

We highly recommend using the LLGs featuring the yellow marking ring with these light sources, though all of Thorlabs’ standard liquid light guides are compatible, taking core diameter into consideration. When using an LLG that does not have the marking ring, there is the risk that the light guide may not be inserted to the proper depth during installation.
With these collimation adapters, users can easily couple the white light output from an HPLS343 or HPLS345 light source to either the epi-illumination or the trans-illumination port of the compatible microscopes above. The broadband spectrum, high brightness, and high color rendering index of these light sources makes them ideal for both fluorescence and bright field microscopy.
Plasma Light Sources with Liquid Light Guide Chapter 5: Operation Operation Chapter 5 SHOCK WARNING High voltage inside. To avoid electrical shock, before powering unit, make sure that the protective conductor of the 3-conductor power cord is correctly connected to the protective earth contact of the socket outlet.
During tuning, the intensity percentage display on the LCD screen will change accordingly. The HPLS343 and HPLS345 light sources feature an intensity tuning function with a range of 0.1% to 100%, with a setting resolution of 0.1%. The tuning knob is functional regardless the state of the shutter (closed or open).
Plasma Light Sources with Liquid Light Guide Chapter 5: Operation 5.5.1. External Shutter Operation The shutter can be controlled via the “SHUTTER CONTROL” port on the back panel. The female BNC port accepts a 5 V CMOS signal. A low logic state will open the shutter and a high logic state will close the shutter. Port Name Connector Signal Type...
Plasma Light Sources with Liquid Light Guide Chapter 5: Operation 5.5.4. Signal Train Figure 10 gives an example of the signal train in the HPLS300 series light source, when set to external control mode. When the “ANALOG IN” signal changes, the light source actually does nothing until a “TRIGGER IN” pulse arrives. Then at the falling edge of the trigger, the light source will start to tune its light intensity according to the “ANALOG IN”...
Plasma Light Sources with Liquid Light Guide Chapter 5: Operation 5.6. Operation Modes The HPLS300 series features three different operation modes: open loop, closed loop, and Eco mode. The light source is set to open loop mode before shipping. The operation mode can only be changed via the software GUI or the command lines as described in Chapter 8.
Plasma Light Sources with Liquid Light Guide Chapter 5: Operation 5.7. Stability and Noise Figure 13 and Figure 14 present detailed light intensity measurements performed for sources operating in open and closed loop modes for 48 hours. The closed loop mode data also applies to operation in Eco mode. Measurements taken before the LLG record only the variation of the intensity emitted by the bulb.
Warning and Errors The HPLS343 and HPLS345 light sources have two different types of malfunction states: warning and error. Warning refers to a state of minor malfunction. The light source is still operational under a state of warning, but it may not perform as expected or according to specifications.
50% of the initial value. It is not an absolute measurement of bulb lifetime. The actual lifetime of each bulb module may vary from unit to unit. Thorlabs provides a one year warranty on the bulb modules. Page 16...
