LASER DIODE MODELS AND FOCUSING OPTIONS
At Osela we provide many different focusing options giving you the flexibility to choose the one that best suits your application. The Streamline laser is free focusable externally without removing any optics. From the graphs below, note the beam size and Depth of Focus (DOF) values and then multiply by the K constants for the laser diode model and focus option of choice (A, B, C, D or E).
Example: From the graphs at 400 mm working distance, Focus = 140μm, DOF = 36 mm. Than for Laser Model 660 nm 130 mW the line thickness at focus for OPTION A will be 212um (i.e.140 um x 1.52). Its depth of focus will be 88.92mm (i.e. 36mm x 2.47).
