Morita's prism to the world !

First Established in Toyohashi City in 1951 "Morita Optical Lens Mfg. Co., Ltd."Since the beginning, we have mainly manufactured "polo prism" and "declination", which are the main parts of optical products such as microscopes, binoculars, and telescopes.We have been manufacturing of products part that you may have touched at least once in your life time.Eventually, due to the evolution of optical products, we started making the porro prism "dach prism".Furthermore, in the manufacturing process, in addition to grinding and polishing, we have established processing technology for thin film coating, prism cementing, and also black painting to prevent ghosts.In this way, Utilizing the manufacturing technology cultivated over many years, we are currently providing advanced microfabrication technology in a wide range of optical equipment fields such as surveying instruments, medical care, communications, and semiconductor manufacturing.While contributing to the development of the japanese optical industry, we will expand the market to overseas.

Conflict minerals response policy

4 minerals mined (tantalum,tin, tungsten, gold)in the democratic republic of the congo and its neighboring countries,those "conflict minerals". we care about they are contributes to the funding of armed groups, conflicts, human rights violations, and also the Environmental destruction.With the cooperation of our procurement partners, our policy is not using "conflict minerals" mined and mediated by armed groups.

Our products

As a manufacturer specializing in optical parts processing that
"bends light and also separates light".

Morita is a manufacturer specializing in processing optical parts specializing in prisms and plane mirrors.
Aiming to be an optical component supply partner that supports the development of the medical, optical, communication, and surveying industries.We continue to take on the challenge of producing high-quality, high-precision optical parts.

Here's some of our product processing results.
We could also manufacture custom products from one lot, so please feel free to contact us after referring to the specifications of similar products.

Micro Prism

less than 5.0mm of polished surface (effective diameter dimensions) product.We aim to contribute to the evolution of the high-capacity and high-speed communication industry by using optical fibers.Also aiming to contribute by downsizing the optical elements that correspond to the miniaturization and high performance of medical equipment such as endoscopes.

Beam Splitter

It's an optical component that divides incident light into two types of light, transmitted light and reflected light, at a predetermined division ratio.It is coated with a dielectric multilayer or metal film that is optimal for the purpose, such as the division ratio.

Mirror

We are accepting the manufacture of thin mirrors, flat mirrors, prism type mirrors, etc.We could vapor deposit the silver, aluminum, enhanced reflective aluminum, and dielectric multilayer are on the glass surface that has been polished with high precision by us.

Right Angle Prism

We would make 45 ° right angle prisms of optical glass such as BK7 it size from 5.0 to 100 mm.

Declination Prism

To deviate the optical axis in any direction we manufacture penta prisms, pecan prisms, rhomboid prisms, and wedge prisms.

Roof Prism / Dach Prism

We could manufacture of the roof prisms with high-precision knife edge processing such as amici prisms and schmidt prisms.

Prism Special type

In addition to prisms such as porro prisms and corner cubes, we also manufacture multiple cemented prism.

Substrate/Window/Filter

We manufacture parallel plane substrates with a parallelism of 5 seconds and optical flats with a surface accuracy of λ / 20.

Production process

Thorough quality assurance system
with integrated build-to-order manufacturing.

Thorough quality assurance and production system to establish product provision that satisfies customers.
We carry out integrated build-to-order manufacturing processes from material arrangement to outer shape processing, polishing, vapor deposition, cementing, cutting, and black painting.

1

Material procurement: Optical Glass

Procurement of BK7, Bak4, synthetic quartz, crystal.Float glass, blue plate, white plate, which are mainly used as substrate glass materials and also we handle other high-refractive materials.We have direct transactions with material manufacturers, and also support glass production lot management (pot management).

2

Grinding

In grinding, the outer shape is processed according to the shape of the prism or mirror to be manufactured.
These roughing processes can be roughly divided into machining and processing by handrails by skilled workers.
It is possible to process multiple shapes such as cylindrical type, right angle type, declination type, and also hexagonal type.

3

Polishing

In the polishing process, optical prisms and mirrors are processed to the product specification accuracy.
With oscar polishing machines, double-sided polishing machines, lapping machine polishing machines, etc., it is possible to handle polishing from extremely small prisms of 1 mm or less to 100 mm size product. from trial product to mass production.

4

Coating

We have skills of a vapor deposition process that can be applied to various prisms such as AR (anti-reflection film), metal film mirrors, half mirrors, and dielectric multilayer such as dichroic mirrors.
Special coats such as a phase coat that reduces the phase shift and also a magic mirror (hybrid coat) in which different coats are layered also correspond.

5

Cementing

Not only 2 pieces PBS cementing but also cement multiple prisms such as 3 pieces cementing available.
Mainly performing epoxy and UV cementing.
It is also possible to cement air gaps and bond fixing brackets to parts such as prisms.

6

Slicing

The size can be cut from 1 to 150 mm and the thickness can be cut up to 20 mm.
With a diamond blade cutting, chipping can be suppressed to 0.1 mm or less.

7

Black Painting

We perform black painting and groove painting such as anti-reflection, anti-ghosting, and protective film processing.
