Fiber Optics


LS-M250 applies direct current type of high efficient metal hallide lamp for light source.
And, mesh intensity control filter for light reduction is applied, make it possible to control intensity from 0% to 100%, without changing color shades.
This is optimum light source for high speed image processing and illumination for line sensor.

LS-M350 is high intensity of illumination type, multiplying 1.5 in comparison to LS-M250 in the past.
By outside control, operation for ON & OFF power supply, arranging intensity, shutter function, 4 filters installation are possible optionally.



  • Hexagonal rod lens is adopted(Intensity of illumination is consistent.) :
    By positioning hexagonal rod lens on lamp's focal point, it is nearly possible to make irregularity of illumination get rid of at the fiber's incoming surface.
  • Twin mirror system is adopted. (Intensity is increased.) :
    By combination of sphere mirror and ellipse mirror, became possible to concentrate all luminous flux, at any cost.
  • Cone plate is adopted. (It is applied for preventing emitting light on center part.) :
    It is possible to concentrate light bundle with small loss at the center. Thus, obtaining small intensity loss and beam bundle with small emission are possible.
