These days, glass reticles are the mainstream. It has the advantage of being able to create complex reticles. This is a method in which the glass surface is etched using chemicals. The etched part is illuminated by the reflected High luminance LED. Non illuminated parts in a glass reticle are formed by chrome evaporation. Reticles other than wire reticles and fiber dot reticles are glass reticles.
The mainstream of reticles nowadays is glass reticle. Manufacturers who can actually make wire reticles are only 1 or 2 companies including us as it requires superb technique of a superior craftsperson. Under a microscope, an artisan places a 6micron (=0.006mm) ultra-fine wire and attaches a dot to the center.
Technically we can make a wire reticle with 4micron but it is too thin to be visible. This is a craftsmanship that requires delicate manual work. Because the wire is just placed on the optical axis there is no glass (lens) that obstructs the transmission of light, which prevents the decrease in transmittance. The lines are very fine which is suitable for precision shooting.
Wire reticle can be assembled in most of our SFP models. CH(cross hair), Dot (1/16, 3/32, 1/8, 1/4MOA dot), Di-plex, LR reticles are wire reticles. These are only available in non-illuminated models.
In a Fibre reticle LED light is guided by the fibre and the cut surface of the tip itself is a LED. This manufacturing technique results in the brightest reticle of all three types. These videos to see how bright a fibre dot reticle is. In the video shows FD-1 reticle. https://www.youtube.com/watch?v=bvfclccnXUM&t=19s https://www.youtube.com/watch?v=nHXIuRjmTEk
Fibre reticles FD-1 & FD-2, assembled in FFP : 1-10×24 Shorty, SFP : 1-4×24 / 1-10×24, 2.5-25×42 & 2.5-25×52, are daylight bright, usable throughout the day.
DR-1 dual reticle in the 1-10×24 Shorty FFP scope adopts a fiber center dot in SFP. (Scale in the dual reticle is in FFP.) The SFP fiber dot does not change its size throughout the entire magnification which will benefit shooters. 1-10×24 Shorty FFP scope assembling the fibre centre dot can be used as a dot sight at low magnification. Also as the SFP fibre dot will not increase its size at higher magnification it is suitable as a precise illuminated dot for long range precision shooting at higher magnifications with the use of the scale as well.
However, each reticle has different characteristics so please choose according to your preference.
