About Us

NITTO OPTICAL is able to produce various optical parts such as multi-layer mirrors from the ultraviolet to infrared ranges.

NITTO OPTICAL can fabricate mirrors and beam splitters for ring laser gyros used for balance control of air planes and rockets, and also high precision cube (cubes for alignment) prisms used for heading reference equipment as parts for injection direction control in thruster for rocket balance control.

NITTO OPTICAL is also able to produce ultra-precision reflection corner cube prisms for satellite tracking systems. The accuracy of beam deviation can be achieved less than 0.5 arc seconds.

Furthermore, NITTO OPTICAL can also provide large flat window glasses of Φ600-1,500mm size, surface accuracy of 1/2λ or less and parallelism angle of one minute or less for Schlieren instruments of wind tunnel tests.
