Provides better Accuracy +-f measurement. High quality optics ensures sharp spectral images while precision machining and fitting allows for precise rotation and accurate measurement. The turntable is mounted on heavy bearing and both telescope and collimator mounted on pillars made from solid metal blocks for added ruggedness and durability. Streamlined body to avoid crevices around fittings.
Has a heavy, sturdy, stable cast metal base, with scratch resistant epoxy-coating. The instrument is mounted on a baseboard,
which easily slides into a polished hardwood case.
