Meeting the Metrology Needs of Laser Optics and
Inrad, two PPGI companies
Quality, of course, is important to everyone.
Metrology serves as a way of quantifying the
parameters of a part and verifying quality.
As a manufacturer of fine optics, responsibility
for testing a component or assembly to specific
criteria lies with us. We take this responsibility
seriously, starting from the beginning of the
quotation process where specifications are studied
from both manufacturing and metrology viewpoints.
The goal of this process is a high-quality
component or assembly that meets or exceeds all
specifications at the final inspection step.
Staffed by optic professionals, our Quality
Assurance department uses a variety of
metrology tools to measure performance of Laser
Optics manufactured components and assemblies.
Frequently, these tools permit in-process testing.
Our inspection system is in accordance with
MIL-I-45208.
Metrology tools used at Laser Optics, summarized
in the table below, allow us to verify our
production processes and maintain the high level
of quality associated with our name. As shown in
the table, Laser Optics uses many different
instruments that have been acquired over a lengthy
period of time. We firmly believe that there are
no quick fixes to providing quality optics whether
in equipment or in experienced and well-trained
manufacturing professionals. The accuracy listed
in the table is typical.
When deemed appropriate, qualified outside vendors
are used to augment our inspection capabilities.
Metrology is a core competency at Laser Optics and
an essential element of our
manufacturing philosophy. Areas of expertise
extend to the routine verification of
mechanical dimensions, inspection of surfaces,
environmental durability, spectral
characterization, and x-ray and laser tests of
crystalline optics.
