The circular beam thermoelectrically cooled (TEC) modules can
be specified to produce an output beam in the between 635 and
830nm and output powers from 0.9mW to 32mW.
The TEC
laser diode module incorporates microprocessor based
temperature control electronics, thermo-electric cooler, heatsink
and fan that enable the
laser diode temperature to be controlled to
a set point temperature between +18ºC to +25ºC, (user adjustable),
and with a stability of ±0.05ºC.
This accurate temperature control, together with user adjustment
of the
laser diode drive current, enables the laser to be tuned to
a region where mode hopping and RMS noise are significantly
reduced or eliminated. Accurate temperature control also produces
excellent wavelength/power stability and cooling the
laser diode to
18ºC significantly increases
laser diode lifetime.
All red, and infrared circular beam TEC
laser diode modules in the
range offer low and high temperature automatic shut-off protection,
analogue and digital modulation capability and safety interlock as
standard.
