Laser Components is promoting what it calls the smallest laser modules available worldwide, available from stock in several wavelengths.
The drive electronics are integrated and the complete modules are barely larger than the laser diode itself, enabling simple connection into any system.
The smallest laser module measuring ø3.3mm is a 650nm dot laser, available either in a plastic or a metal housing. The plastic version has a maximum output power of less than 0.9mW, whereas the metal housing has an output power of less than 3.0mW.
For larger diameters between 6.2mm and 10.5mm, wavelengths other than 650nm are also available. In addition to the red at 635nm, there are also versions available at 780nm and 850nm, both of which are not visible to the human eye.
