Lenses

Wide range of high precision products are made possible by a strong engineering background

Optical Element Machining Technology is a processing technology built up in the manufacturing of Ricoh Camera, replacement lenses and lenses for a copying machine. These technologies were developed further onto the application toward LSU (Laser Scanning Unit) , Optical Engine for PJ (Projector) , and projection lens units with a higher quality standard attained.
We have met strict requirements for high precision, especially on lenses for LSU by developing and manufacturing our own tooling and machinery in-house, combined together with years of know-how.Our further progressing to achieving extremely high precision of f-theta lens, Toriclens, cylindrical lens, and mirrors, has permitted a wide variety of applications of LSU in specialty field, such as medical equipment, commercial printing machines, and printers for photographic laboratory.
Moreover, along with the establishment of business division for Optical Engine used in projectors and other projection lens units, we have been focusing on manufacture of large diameter lens, in-house production of cross-prisms, and the processing of various planer polishing. Our proven cases with customers and years of practical experiences have enabled us to handle various requirements over a wide range.
Having a strong engineering background, RINS continues to supply lenses of an even higher quality that virtually enhances the features described in customers' technical drawings. This can be achieved, because RINS fully understands the characteristics of customers' products and its application, and would develop them fully in optical element processing.

Processing Examples

f-theta lens Diameter:φ300 or less
Toric lens For scanning direction :R300 or less, For processing direction :R150 or less
Cylindrical Lens At R300 or less, L(Length) is 140 or less.At R150 or less,L may be up to 510.
Spherical lens Up to around φ300 is available.
Glass Molded Lens Large diameter (φ43) has been achieved.
Cross-prisms □21, □26, □32, □38, □45

Cemented lenses, and combinations of diverse lens surfaces can also be done

Various optical materials, quartz, fluorite, and special materials such as Ge, can also be supported.
