Optics designed and built in-house, since 1961.
SIGHTRON JAPAN was founded in 1961 as Tasco Japan. Today SIGHTRON designs and produces its optical instruments in-house — riflescopes, binoculars and telescopes such as the SJH-75UF.
Many optical makers exist today, but very few produce in-house. Most outsource manufacturing, or outsource everything from design to production.
SIGHTRON is one of the few optical makers in the world that keeps the entire process — from development and design through to sales — in-house.
SIGHTRON JAPAN works with established names in optics and precision equipment.
