Masuyama = Ohi Optical Manufacturing

Let me write up the summary of the legendary company history and background.

[Masuyama] is originally the name of the founder. A current owner is still Mr.Masuyama, so the founder’s philosophy continues to be alive and all are still fully produced in Japan. Deeply concentrating on Japanese production. That’s the excellent company policy.

For inventing low-power ultra wide field eyepieces in 1943. Probably this might be the origin of today’s Masuyama brand super wide.

Meanwhile, Ohi Optical Manufacturing Co., Ltd.(OOM), which is the name of company. As Nikon serious fan might be aware, [Ohi] is the name of the location inside Tokyo, which is well known as Nikon’s home ground. Let’s say like Rochester of Kodak? and Jena of Carl Zeiss?? maybe something like that.

So more than half century ago, OOM started the business besides “Nippon Kogaku Kogyo Co., Ltd (an original name of Nikon) to provide eyepieces to Nikon. It seems to have been very close relationship each other.

A following is one example. This was the award from Nikon for inventing eyepieces to the founder – Ichiharu Masuyama in 1946.

Since then, they have been making high quality optical products including various eyepieces. Current Japanese Abbe Ortho eyepieces are known as OOM production too.

These were Ohi Optical Abbe Ortho Hutech used to carry

Also they, as OEM, made so many number of eyepieces under various brands so far.

Masuyama philosophy still exists in the products. This is to summarize current super-wide Masuyama brand eyepieces.
