Cool modules extend laser diode lifetimes
New thermoelectrically cooled laser diode modules offer exceptional wavelength and power stability, greatly increased pointing accuracy and significantly extended laser diode lifetime.
The new range of 635nm circular beam laser diode modules requires an input voltage from 2.7 to 6V at a typical operating current, of 31mA, circularity ratio is typically 1.2:1, beam divergence 0.6mrad, operating temperature from -10 to +50C and a standard flying lead length of 300mm, Hitachi's "MARU beam series" of red laser diodes offers the world's first circular beam with a 1.2 (typical) aspect ratio for laser diodes in the 635nm wavelength band.
The shift from the previous elliptical beam to this circular beam makes it possible to simplify the beam-forming optics required in products such as laser levellers, scanners and fibre checkers, resulting in significant cost savings. Request a free brochure from Photonic Products ...
