United Lens Company (ULC) was founded by Fileno DiGregorio and his brother Sabatino DiGregorio in 1916. They started out as a small shop with only $450 in capital and one molding furnace.


In 1934, ULC was incorporated and officially became United Lens Company, Inc.

In 1935, Sabatino left the company to return to his family in Italy.

Anthony Deterando joined the business in 1936 as Vice President.

Shortly after, Fileno’s sons Albert (Al), Richard, Raymond and Ronald all joined the business in 1937.

WWII began in 1939, and ULC was called upon by the U.S. government to supply lens blank elements for critical military instruments being developed.


ULC celebrated their 25th year of business in 1941.

In the late 1940s, we also expanded our molding facility space and added an area to include larger offices and a main stocking room for our finished molded products.


Al became Plant Superintendent in 1950.

Ronald became Assistant Plant Manager in 1957.

Richard DiGregorio was promoted to Plant Manager in 1953.

In 1959, Fileno was designated “Boss of the Year” by the Southbridge Chapter of the National Secretaries Association for his outstanding leadership qualities.


ULC had a devastating fire in 1960 that burned down almost half of the building. Out of pure determination to succeed despite the fire, we were back up and running the next day. Repairs were being made to one side of the building while parts were being made on the other.

In 1963, Fileno met privately in Italy with Pope Paul VI.

Fileno was awarded the “Man of the Year” Award by the Don Orion Home in East Boston in 1964.

Al became Executive Vice President of United Lens in 1965, while Anthony was also promoted to Assistant to the President.

ULC celebrated their 50th year of business in 1966.

In the mid 1960s, we expanded further, adding on additional space to encompass increased cutting abilities and storage for our molding tools. We also added additional warehousing space in a separate building, directly across the street from the main facility.

Fileno received the Honorary Degree of Doctor of Humanities from Franklin Pierce College in Rindge, New Hampshire for “fifty years of civic and philanthropic leadership and benevolence.”

In 1969, ULC made it to the moon! Apollo 11 had landed on the moon, transmitting pictures back to Earth through a lens made from ULC blanks.


ULC began making sagged blanks in 1970.

In 1972, Fileno received both the Distinguished Citizen Award from Governor Sargent of Massachusetts and a Commendation from President Nixon.

We began grinding and polishing flat lenses in 1973, as well as offering thin-film coating services. Fileno also received an Official Citation from the Massachusetts House of Representatives that same year.

A few years later, we expanded again, adding additional space to accommodate our rapidly increasing demand for machined blanks.

Fileno celebrated his 90th birthday with a party thrown inside the plant with all his employees. Fileno was honored by his business associates in the glass industry as well receiving special gifts from Corning Glass Works and SCHOTT Optical Glass, Inc. to mark this important milestone. Among the many cards, telegrams and letters of congratulations were a special citation from former Governor Sargent and a letter from President Ford.

In 1978, UL West opened in Anaheim, CA, stocking fine annealed glass and providing various machining services utilizing the STC, ID saws, CNC edgers and other milling machines.

During 1978, Anthony passed away, Richard got promoted to Vice President and Ronald to Vice President of Sales.

William (Bill) Lannon started work at ULC in 1979 and was quickly promoted from Utility Operator to Coating Technician.


The ULC team mourned the death of their founder, Fileno DiGregorio, who passed away in 1980 at 95 years of age. Al became the President and treasurer of ULC shortly after, with empowered determination to carry on the family business.

The Service Center department opened in 1982 and started offering added machining services to the already existing molded blanking capabilities, as well as an optional machined blank alternative.

In the early 1980s, we began a large expansion which would add on a second and third floor to be used for both additional offices and production space.

UL West closed down in 1983 and all machining services were moved back to the main facility in Southbridge, MA.

ULC acquired Universal Blank Company from Henry DiGregorio.
