The LO setting is safer for testing and is also used for low energy
applications such as polymide passivation removal with UV. Ask your
New Wave Research sales engineer or representative for application
guidelines and useful techniques.
The output wavelength emitted by the laser is selected using the
wavelength selector switch located on the remote control box. Select the
output wavelength by turning the wavelenght selector knob to the
corresponding LED indicator:
LED Indicator Wavelength
Red 1064 nm (IR)
Green 532 nm
Blue 355 nm or 266 nm (UV)
NUV (near ultraviolet) objective lenses must be used to
transmit UV (355nm) energy. NIR (near infrared) objectives
lenses must be used to transmit IR energy. Green light can
pass through standard, NIR or NUV lenses.
Do not use standard objective lenses with IR or UV wavelengths.
These wavelengths may damage the standard lenses.
Spot Marker
The spot marker highlights the area which will be irradiated
by the laser pulse. The spot marker and laser both travel
through the same X-Y aperture, thus adjusting the aperture
determines the shape and size of the area to be irradiated.
To achieve the best cut definition, focus the microscope so
that the aperture edges are in sharp focus.

The 150W white light external spot marker is controlled by the
ON/OFF switch located on the spot marker chassis. A potentiometer
allows variable control of the intensity. If the spot marker power cord
is plugged into the outlet on the back of the laser power supply, then
the spot marker may be turned ON and OFF using the “Marker”
switch on the remote control box.
Note: The image of the spot marker is more visible when the
microscope’s background lamp is reduced in intensity. Also,
the microscope illuminator has a sliding aperture control.
Reducing the aperture tends to increase the depth of the
