Product Overview:

CM Series has been additionally fitted with anamorphic optics which reduce beam divergence. Thanks to this effect, despite the same power, the laser is even several times more visible to the human eye. Besides the fact that this series uses the strongest laser diodes available on the market at a given wavelength range, the beam is additionally improved so that its visibility is strengthened and the smallest posiible dot can be formed at large distances. Microcontroller driving the laser module is responsible both for soft start of the laser diode and the regulation of temperature by using a thermocouple. In addition, in the event when adequate heat dissipation of the module is not ensured, the system protects the diode from overheating, and when the temperature of the diode exceeds 40 degrees Celsius, it prevents further current flow through the diode and goes into alarm mode. With a separate analogue part of the laser diode power supply, the laser is able to modulate the beam in accordance with the analogue input signal (0 - 5V) even at frequency of up to 80 kHz. The diode along with the entire optical system is mounted in a stylish housing which ensures both protection and cooling. To enable continuous work of the module, for example in a laser projector, it must be placed on an aluminum plate which allows for heat dissipation (thermal grease significantly improves the cooling of the module). It is a solution that not only saves space in the projector cabinet, but also reduces the level from which the beam is emitted. This is aimed at meeting the demands of customers who more often than not look for compact high-power modules.
