Everything you need to know about our Company

The Company

In 2010, DFVasconcellos launched the new factory. The entire production process has been logically designed in order to further improve the quality of our products.
The modern factory replaces the previous plant of São Paulo with greater efficiency, whose process no longer supported the market demands.
It is in the city of Valença, state of Rio de Janeiro, between three of the main Brazilian markets, Sao Paulo and Belo Horizonte and Rio de Janeiro, and close to the main ports essential for export.
For the installation of the factory, the company invested several hours in training local staff, combining the great experience of former employees with the will to overcome, which is the local characteristic.
All of this makes DFVasconcellos fit for new challenges without ever losing focus on the quality of its products, the high technology and the ability to invent that have always been part of its history.

Valença – A strategic place

Located in the state of Rio de Janeiro, Valença was the city chosen by DFVasconcellos for its headquarters after the former factory in Indianapolis, Sao Paulo was decommissioned.
Valença offers a strategic position as it is located between 3 of the main consumer markets (Sao Paulo, Rio de Janeiro and Belo Horizonte) and close to the main Brazilian ports.
The city has 2 colleges and great government incentive for its full growth.


DFVasconcellos inaugurated the new factory and company headquarters on July 1, in Valença, Rio de Janeiro.
Founded in 1941 years ago and a pioneer in the optical sector in Brazil, DFV owns about 60% of the national market of microscopes directed to the medical-hospital area.
On July 1, 2010, the company arrives in Valença, Rio de Janeiro, inaugurating a new phase of its business with the start of operations of its modern factory.
Logically designed, the new unit will further improve the quality of the products that D.F.Vasconcellos develops and the services it provides.
Generating, in this first moment, 150 direct jobs in the region, the new installation is born betting on the future with the expansion of new markets and repressed demands.
With an investment estimated at R $ 10 million, the new D.F.Vasconcellos factory has a highly specialized workforce.
The choice of the city of Valença to build the new facility was motivated by the fact that the city has a strong affinity for industrial activity, as it housed one of the largest weaving centers in Brazil, as well as having a large supply of higher education institutions.
Another important factor determining our decision is the development vision of the Rio de Janeiro State Government, which meets our growth and modernization plans,” says DFVasconcellos management.
With a visionary spirit, DFVasconcellos is attentive to the possibility of developing products linked to new markets, such as robotics, thermo-optics, electronics and others.
Thus, the construction of the new factory corroborates the company’s new plans, which include increased exports of its products.
DFVasconcellos serves the largest offices and hospitals in Brazil in the demands of microsurgery and its technology is also present in 66 other countries.
DFVasconcellos’s massive business is underpinned by three pillars: optics, precision mechanics and electronics; and the company’s success is directly linked to its technology directed to the medical-hospital area present throughout the Brazilian territory.

DFV Profile

A pioneer in the country’s optical sector, DFVasconcellos stands out for its active participation in the development of the microsurgery field in Brazil.
Currently, more than 60,000 surgical microscopes produced by DFVasconcellos are installed in hospitals and outpatient clinics in Brazil and 66 other countries.
With a new administration, the company’s new plans include enhancement to better serve the demanding microsurgery market, supplying this segment in Brazil and worldwide.
DFVasconcellos products are essential in microsurgery in various medical specialties: Neurosurgery, Gynecology, Dentistry, Ophthalmology, Otorhinolaryngology and Veterinary.
Founded in April 1941, the company began its activities by developing military-grade equipment such as shore-ship observing instruments, night vision equipment and even trench observation instruments – DFVasconcellos technology was also used in homing missiles.
Later, the company specialized in the production of cameras, telescopes and microscopes, among others.
From the late 1970s until the mid-1980s, the company developed carburetors for the auto parts market.
With the advent of electronic injection in the auto industry, carburetor manufacturing has lost ground in D.F.Vasconcellos’ product hall, which is now devoted to the optical industry. For this, it absorbed and developed technology from precision mechanics.
