The company’s green laser diode modules are said to be ideal for spectroscopy, particle measurement, interferometry, holography, robotic control, and flow visualization. The model 2501 is a fixed-focus CW diode pumped laser diode module with a beam divergence of <1.2 mrad. The laser housing measures 11 mm in diameter and 37.39 mm in length. The front of the module has been designed with threads so additional optics can be easily added. The model 2503 has a beam divergence of <0.8 mrad. The laser housing measures 12 mm in diameter with a length of 47.4 mm. Both modules require 3 V DC with operating current around 300 mA. BEA Lasers, Inc.
