Princeton Optronics Inc. (Mercerville, NJ) has introduced a VCSEL-based miniature line generator. The wavelength of the line generator is in the 820- 840nm range, has a 20mW CW power output, a fan angle of 80 degrees, line uniformity of 75-85%, a 1/e2 linewidth of 2.5mm at a distance of 50 cm. The size of the line generator is 4x6x5mm. Such products can be made using Princeton Optronics VCSELs at wavelengths from red to 1064nm, with output power up to several hundred mW. The line generators are used in applications such as machine vision, consumer electronics and instrumentation.
