NITTOH KOGAKU K.K.

Using advanced plastic molding technologies and high quality coating technologies cultivated through our lens molding operations, and using an integrated assembly and production system, Nittoh also manufactures various precision devices. When manufacturing waterproof cases and cradles for cameras, we use the same high quality manufacturing technologies that we use for the camera bodies.
We also have the systems in place to guarantee performance of our products. We have established inspection systems using advanced equipment such as water pressure testing equipment to test waterproofing up to 45 atmospheres, and temperature testers to test heat and cold resistance.
