Feature Stories - Story12: Optical Technology

RICOH's special stories to present a new value beneficial to the world.

Ricoh Managed Document Services help improve your core-business productivity.

Working with documents: viewing them, signing off on them, receiving and inspecting them. It can get complicated and time-consuming. If documents ? both print and electronic ? are not managed in a centralized way, employees can waste far too much time searching for or recreating information that already exists. Is your enterprise being held back by this kind of productivity drain? Ricoh Managed Document Services (MDS) can help.

Besides dramatically reducing operating and management costs, Ricoh MDS gives your employees rapid access to your information resources, empowering them to process information more efficiently. By relieving you of the burden of document management, Ricoh frees you up to focus on your core business. As a result, productivity is enhanced.

Ricoh’s technical strengths are built on the tradition of “optical technology” the company has continued since its foundation.

The "Ricoh" name comes from the "Ri" of "Riken" and "Coh", written with the character for light.
"Riken" is the name of an institute of physical and chemical research, founded in Japan in 1917 to carry out research in fields such as physics, chemistry, engineering, biology, and medicine*1. Ricoh was founded in 1936 as "Riken Kankoshi Co., Ltd.", in order to sell the photosensitive paper developed by Riken.
Its name was later changed to "Riken Optical Co., Ltd.", and then, with further expansions in the range of products and services, the name was changed again in 1963, to the current name, "Ricoh Company, Ltd."

Ricoh's "optical technology", which began with photosensitive paper, have gone on to include lenses, mirrors, lasers, and other optical components, as well as copiers and multifunction printers, printers, fax machines. These optical technologies have become the foundation of Ricoh's technical strengths, applied to fields such as office solutions, printing, imaging, and devices, creating a wide range of products and services.

Controlling Total Light ?Free-Form Mirrors and Precision Molding Technology?

The PJ WX4130/WX4130N ultra-short-throw projector was launched in 2011. This is the product that Ricoh's optical technologies have created. The PJ WX4130/WX4130N can project a large 48 inch image onto a screen or wall from a distance of just 11.7cm.
This ultra-short-throw projector, designed with an emphasis on short focal distance, contains an optical mechanism which uses a special curved plastic mirror called a free-form mirror. We at Ricoh use our own unique precision molding technologies*1 and processing technologies to create the high precision plastic mirrors that make it possible for this projector to display large images at close distances, without distortion.

Creating Light with Semiconductors ?Laser Light Source (VCSEL) and Light Control Technology (VCSEL Controller)?

Production printing has the increasingly diverse printing needs of the commercial print market. The ultimate in "optical technology" is seen in Ricoh's production printers as well. Ricoh has developed the first-emitting semiconductor called VCSEL(Vertical Cavity Surface Emitting Laser) and its controller, that enabled precise and high-density laser writing using 40 beams in a space of 1mm2.
This mechanism is applied to the RICOH Pro C751EX/C651EX, making characters and fine lines clearer, and offering a high resolution of 4800dpi, for even clearer image reproduction. This is why we can provide printing environments requiring high image quality and high speed.

With long years of research and development in "optical technology" as the core, we at Ricoh provide new value to the customers through products and services.
