TECHSPEC® Multi-Element Inner Apertures provide complete control over beam shape and size in optical systems. Aperture diameters are available from 1mm to 15mm for applications that requiring small to large beam sizing. TECHSPEC® Multi-Element Inner Apertures feature a dull matte finish to reduce internal stray light and reflections. For optimal placement of the aperture within the system, use TECHSPEC® Multi-Element Spacer Rings and Spacer Tubes for precision positioning.
Note: The TECHSPEC® Multi-Element Inner Aperture Plate Kit (#11-187) offers our full range of aperture diameters at a reduced price.
