Optoswitches, optical hybrids, custom assemblies, photodiodes, phototransistors, IR
emitters, and photoconductive cells for industrial, commercial, and consumer electron-
ics applications.

PerkinElmer Optoelectronics has the distinction of being one of the foremost manufacturers in
optoelectronics. Founded in 1947, PerkinElmer offers its customers over 35 years experience
in the development and application of optoelectronic devices. The product line is one of the
broadest in the industry, including a variety of standard catalog products as well as custom
design and manufacturing capabilities. Approximately 75% of the products shipped are cus-
tom designed and tested to serve the needs of specific OEM applications.

Three basic objectives guide PerkinElmer's activities - Service, Quality, and Technology.
Our outstanding engineering staff, coupled with the implementation of modern material control
and manufacturing techniques, plus our commitment to quality, has gained PerkinElmer "certi-
fied" status with many major customers. Products are often shipped directly to manufacturing
lines without need for incoming QC at the customer's facility. PerkinElmer's products are verti-
cally integrated, from the growing of LED crystals, silicon die fabrication, package design, reli-
ability qualification, to assembly. Vertical integration is your assurance of consistent quality.

Recognizing the need for low-cost manufacturing to serve world markets, PerkinElmer
expanded its manufacturing/assembly operations into the Far East more than 20 years ago.
The combination of strong technology in processing at the St. Louis headquarters and low-
cost assembly operations in the Far East has allowed PerkinElmer to effectively serve all
markets, worldwide. PerkinElmer provides optical sensors, IR emitters and subassemblies for
such diverse applications as street light controls, cameras, smoke alarms, business
machines, automotive sensors, and medical equipment.

Custom and Semi-Custom Devices

Upon request, and where sufficient quantities are involved,
PerkinElmer Optoelectronics will test standard parts to your
unique set of specifications. The advantage of testing parts
under actual operating conditions is predictable performance in
the application.

PerkinElmer offers a broad line of standard photodiodes in a
wide variety of packages and sensitivities. Nevertheless, some
applications demand a totally custom device. Recognizing this
real need, PerkinElmer's engineering, research, and sales
departments are geared for working with the customer from
initial concept through design, prototype, and volume production.

A custom design usually required the commitment of valuable
resources. PerkinElmer reviews requests for custom devices on
a case by case basis and reserves the right to decide if the
business potential warrants the undertaking of such a project.
The customer may be asked to share in the expense of
development.

PerkinElmer has designed and fabricated custom products for
many companies. PerkinElmer's staff can work closely with the
customer and protect proprietary information. A custom design

Your inquiries to PerkinElmer should include electrical,
environmental, and mechanical requirements. Also, information
on anticipated volumes, price objectives, and lead times is
helpful since these often determine the choices of design and
tooling.
