Features

N-BK7 Substrates

N-BK7 is a relatively hard Borosilicate glass that offers good scratch resistance with a very low level of inclusions. For more information, refer to the optical material technical note.

High Reflectance of EAG.1

Ideal for use with ultrashort pulse lasers, EAG.1 coated high reflectance beamsteering mirror gives R>99% 600-1000 nm at 0 deg AOI, Rp>98.5% 580-1000 nm and Rs>99% 540-1000 nm at 45 deg AOI.

Near Zero GDD of EAG.1

Careful thin film coating design and advanced coating processes result in minimum effect on pulse dispersion. The absolute value of GDD is an astounding less than 5 fs2 from 550 to 1050 nm.
