PerkinElmer

PerkinElmer is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PerkinElmer rather than just read about it. In short: PerkinElmer, Inc., previously styled Perkin-Elmer, is an American global corporation that was founded in 1937 and originally focused on precision optics. Over the years it went into and out of several different businesses via acquisitions and divestitures; these included defense products, semiconductors, computer systems, and others.

Key takeaways

  • PerkinElmer belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect PerkinElmer to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of PerkinElmer from memory before moving on to harder problems.

Reference excerpt

PerkinElmer, Inc., previously styled Perkin-Elmer, is an American global corporation that was founded in 1937 and originally focused on precision optics. Over the years it went into and out of several different businesses via acquisitions and divestitures; these included defense products, semiconductors, computer systems, and others. By the 21st century, PerkinElmer was focused in the business areas of diagnostics, life science research, food, environmental and industrial testing. Its capabilities include detection, imaging, informatics, and service. It produced analytical instruments, genetic testing and diagnostic tools, medical imaging components, software, instruments, and consumables for multiple end markets. PerkinElmer was part of the S&P 500 Index and operated in 190 countries. Over its history, PerkinElmer has been split in two twice. In 1999, PerkinElmer merged with EG&G, with the ongoing Analytical Instruments Division of Perkin-Elmer keeping that name, while the life sciences division of the company became the separate PE Corporation. In 2022, a split of PerkinElmer resulted in one part, comprising applied, food and enterprise services businesses, being sold to the private equity firm New Mountain Capital for $2.45 billion and thus no longer being public but kept the PerkinElmer name. The other part, comprising life sciences and diagnostics businesses, remained public but required a new name, which in 2023 was announced as Revvity, Inc.

History

Founding Richard Perkin was attending the Pratt Institute in Brooklyn to study chemical engineering, but left after a year to try his hand on Wall Street. Still interested in the sciences, he gave public lectures on various topics. Charles Elmer ran a firm that supplied court reporters and was nearing retirement when he attended one of Perkin's lectures on astronomy being held at the Brooklyn Institute of Arts and Sciences. The two struck up a friendship over their shared interest in astronomy, and eventually came up with the idea of starting a firm to produce precision optics. Perkin raised US$15,000 from his relatives, while Elmer added US$5,000, and the firm was initially set up as a partnership on 19 April 1937. Initially, they worked from a small office in Manhattan, but soon opened a production facility in Jersey City. They incorporated the growing firm on 13 December 1939. A further move to Glenbrook in Connecticut in 1941 was quickly followed by another move to Norwalk, Connecticut, where the company remained until 2000. The opening of World War II led to significant expansion as the company produced optics for range finders, bombsights, and reconnaissance systems. This work led to the U.S. Navy awarding them the first "E" for Excellence award in 1942.

Perkin-Elmer retained a strong presence in the military field through the 1960s and at the same time was significantly involved with OAO-3 a 36-inch Ultra Violet Space Telescope and Skylab. They contributed to the Apollo program by development of a CO2 sensor that was, however, supplanted by a Coleman Instruments product. PE at the Norwalk plant also conducted one of the first researches into computer-digital enhancement of scanned images, contracted for application to the Corona spy satellite, film imagery. They were a primary supplier of the optical systems used in many reconnaissance platforms, first in aircraft and high-altitude balloons, and then in reconnaissance satellites. A significant advance was 1955's Transverse Panoramic Camera, which took images on 12 by 14 ft (3.7 by 4.3 m) wide frames that provided single-frame images from horizon to horizon from an aircraft flying at 40,000 ft altitude. Such systems remained a major part of the company's income, capped by the installation of laser retroreflectors on the Moon as part of the Apollo 11 mission. Elmer died at age 83 in 1954, and the company began trading shares over the counter. The company was listed on the New York Stock Exchange on 13 December 1960. Perkin remained as president and CEO until June 1961, when Robert Lewis, previously of Argus Camera and Sylvania Electric Products, took over these roles. Perkin remained the chairman of the board until his death in 1969.

Semiconductor manufacturing In 1967, the U.S. Air Force asked Perkin-Elmer to produce an all-optical "masking" system for semiconductor fabrication. Previous systems used a pattern, the "mask", which was pressed onto the surface of the silicon wafer as part of the photolithography process. Small bits of dirt or photoresist would stick the mask and ruin the patterning for subsequent chips, and it was not uncommon for the vast majority of the chips from a given wafer to malfunction. The Air Force, which by the late 1960s was highly reliant on integrated circuits, desired a more reliable system. Perkin-Elmer responded with the Microprojector, which was essentially a large photocopier system. The mask was placed in a holder and never touched the surface of the chip. Instead, the image was projected onto the surface. Making this work required a complex 16-element lens system that focussed a narrow range of wavelengths of light onto the mask. The remainder of the light from the 1,000 watt mercury-vapor lamp was filtered out. PE also developed a micro-densitometer in 1967 that scanned micro-chips for quality control Harold Hemstreet was convinced that the concept could be simplified, and Abe Offner began the development of a system using mirrors instead of lenses, which did not suffer from the multispectral focussing problems of lenses. The result of this research was the Projection Scanning Aligner, or Micralign, which made chip making an assembly-line task and improved the number of working chips from perhaps 10% to 70% overnight. Chip prices plummeted as a result, with examples like the MOS 6502 selling for about US$20 while the previous generation of designs like the Motorola 6800 sold for around US$250. The Micralign was so successful that Perkin-Elmer became the largest single vendor in the chip space in three years. In spite of this success, the company was largely a has-been by the 1980s due to their late response to the introduction of the stepping aligner, which allowed a single small mask to be stepped across the wafer, rather than requiring a single large mask covering the entire wafer. The company never regained their lead, and sold the division to The Silicon Valley Group.

Worked examples

Example 1 — a first encounter with PerkinElmer

Start with the simplest possible case. Write down what PerkinElmer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PerkinElmer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PerkinElmer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PerkinElmer

In research
PerkinElmer appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses PerkinElmer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
PerkinElmer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Waltham, Massachusetts, Companies formerly listed on the New York Stock Exchange, Defunct computer companies of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for PerkinElmer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
