Description

BAK4 V.S. BK7 Fiturbo F1025 is equipped with BAK4 Glass, and why is it a better choice? --The higher refractive index rate and the complete, circular shape of the exit pupil will mean more light will be transmitted to the entire field of view. This will mean brighter, color-rich, and sharper edges of your periphery. On the contrary, BK7 glass has lower refractive index rate compared to BAK4 and will produce distortion around the edge of the exit pupil.Roof V.S.
