This BRIGHTLINE 532 mm Alignment Laser will work well on a variety of machines, and on dark surrfaces shows up better than the common Red line. -- The 5 mW Green line shows four to five times more visable to the human eye than an equally Powered Red line. -- The output power is 5 mW; 100º fan angle. -- Expected life 3,000 - 5,000 hours. -- Projection type (dot/line/cross): Dot. -- Package includes: Alignment Laser mounted in a block, Mounting bracket and power supply. This light can also be powerd by direct 3.0 VDC (300 - 800 mA draw). -- Laser beam thickness at aperture is 3 mm with a divergence of 0.1 mm for every meter of beam length. This is a focus adjustable laser with an operating temperature of 15C - 35C.

This BRIGHTLINE 635 Mm Alignment Laser will work well on a variety of machines. It is ideal for any aplication where a highly visible line projected onto a surface is needed. -- The output power is 5 mW; 100º fan angle. -- Expected life 3,000 - 5,000 hours. -- Projection type is a line and is focus adjustable. -- Package includes: Alignment Laser mounted in a block with mounting bracket and a direct 3.0 VDC (300 - 800 mA draw) power supply. -- Line straightness better than 0.1% over full length, line divergence (beam diameter) will expand 0.3 mm for every 1 meter increase in distance from the Laser to the target surface. The beam diameter at the aperture is 4.0 mm. -- Operating temperature is -10°C to +40°C.
