Photonic Products has developed a line of compact and affordable laser modules generating an accurate line or cross at 635 or 650 nm with uniform intensity distribution. The laser modules measure just 29 mm long with a diameter of 8 mm and are efficient and reliable. They are ideal for the most demanding industrial and medical applications where space is at a premium, such as machine vision, targeting, alignment and handheld instrumentation. These laser diode modules generate either a 70-degree full angle cross or a 58- or 88-degree full angle line, all factory focused at 1000-mm. The focus can be set to other distances on request. At either 650 635 nm, these compact laser diode modules offer output powers of 0.9 or 4 mW, with power stability of less than 5 percent. Operating voltage is from 3 to 6 V DC at an operating current of 30 mA typ (0.9mW) or 40mA typ (4mW). Operating temperature range is -10 to +40 degrees C. The modules consist of a brass housing, a laser diode, drive circuit and beam-shaping optics. Electrical connections are made via external flying leads. All modules have static, surge and reverse polarity circuit protection.
