DOT
   
- LD(Laser Diode) as a light source generates laser beam with a specific angle and wavelength.
- Transmitted laser beam through a lens is collimated and elliptical dot beam.
- An user can adjust the beam size by movement of lens group.
- The lens called a collimator can’t make an ideal collimated beam.
- The collimated beam always have very low divergence angle.
- Because LD emits a beam of different divergence angles of vertical and horizontal direction,
the shape of dot has an elliptical beam shape.
LINE
   
- The single line beam is made from collimated or focused beam by deflection lens or cylinder lens.
- The modules make the fan angle of 10, 15, 30, 45, 60, 90, 120 degree.
CROSS
   
- The cross line beam is made from collimated or focused beam by deflection lens, diffraction lens or two cylinder lens.
- Low power modules (below 5 mW) make the fan angle of 5 or 50 degree, and other modules make the fan angle of 10, 15, 30, 45, 60, 90, 120 degree.
GREEN
   
- This Green laser emit laser beam of 532nm wavelength using DPSS method.
- DPSS(Diode pumped solid state) method means that it use high power 808nm LD(laser diode) as pumping energy source and it emit green laser through DPM composed of Nd:YVO4,KTP.
- Moreover, Because Green laser using DPSS method has singular divergence angle,we must make the collimation beam using collimator.
- It generates stable output power with external PD(Photo diode) feedback. 532nm Green beam is more visible and bright to the human eye.
- So, we can use green laser in the system of measurement, positioning, lighting, alignment, guideline, leveling, machine vision etc.
Adapter & Bracket
   
- Bracket : We have 3 types(B, D, E) of bracket mounting for laser modules.
Please select proper brackets.
- Adapter : Module must be biased by the constant DC voltage(5V or 12V)
LD & LENS
   
- As light source, we use high reliability LD and have various type & output power LDs.
- Lenses are a use for collimator composed of plastic or glass lenses.
