Improved Transmittance of Optical Glasses
E-FDS1-W

E-FDS1-WOur glass type E-FDS1 (nd=1.92286、νd=20.88) which have been widely used, now have been improved to「E-FDS1-W」of its transmission. Although the transmittance has been improved, the composition and the combination of raw materials has not been changed. So the other characteristics stay the same.
