With fiber optics ambient (day)light can be collected and directed to an illuminated daytime reticle. Many reticle illumination and pattern options are available. Mid Range/Tactical Illuminated Reticle Dayscope. With any illuminated low-light reticle, it is essential that its brightness can be adjusted. There is no need for other optical elements to focus light behind a reticle. These areas of photoresist and no photoresist reproduce the pattern on the reticle. Usually, only the center of the reticle is illuminated. Many binoculars have a range finding reticle (scale) superimposed upon the view. The stepper passes light through the reticle, forming an image of the reticle pattern. The choice of red dot reticle size depends on the user needs. The MC-10-80 has an anodized aluminium housing, and has a similar black reticle. Reticle clamp cleanliness is therefore required to be maintained. The width of the trunk is measured as so many units of the reticle scale. The analog stick is used to control the reticle. Total station instruments do not have stadia lines marked on the reticle.
