| "Classic optics programs use "ray tracing" as a way to prove an optical design. Individual light rays are geometrically plotted at every refracting and reflecting surface. In an ideal world, each and every ray launched from a point of no dimension would travel through the optical system and end at a point likewise of no dimension. Sadly, the real world does not allow this ideal, and so the point becomes a spot of some dimension. The better the design, the smaller the spot."
Mel Decker went to work
for Harold Newman at Sage Instruments in 1960. Sage was then
doing custom medical instrumentation. In 1967, Sage was sold to
a larger organization whose interests were not in the optical
area. Mel began to form the idea of going independent. The
people who sell research microscopes are an impressive group and
the opportunity to work with them was appealing.
Finally, in 1970, with
Harold's encouragement Opti Quip was born. The purpose, then and
since, has been to offer accessories to improve the performance
of the research microscope.
Opti Quip's first
product, the Model 220, was an advanced unit to take time-lapse
and high-speed movies through either an inverted or upright
microscope. To be used with this unit was the Model 335 infrared
incubator, making use of a focused beam of infrared heat,
controlled by a miniature temperature probe.
In 1972 Opti-Quip
offered its first power supplies for a variety of mercury and
xenon lamps. These power supplies required a large variety of
sockets to fit the various lamphouse/lamp combinations.
Improvements were continuous, but the large variety remained a
problem.
In 1984 a second
generation of power supplies was launched. The Model 1500 could
handle the requirements of five different arc lamps. The 1500
showed the superiority of a new 150 watt xenon lamp from Osram,
more intense, more stable, ozone free, and with a 2000 hour life
expectancy.
At this same time, most
major microscope manufacturers decided to discontinue their
large lamphouses, which this 150 watt lamp required. Opti Quip
therefore decided to design and produce a lamphouse that would
run cool, fit every make of microscope, and have a universal
lamp mounting system that would not require a separate special
socket for each and every lamp. The result was the Model 770.
Now with the help of two lamp length adaptors and six separate
trigger wires, a variety of lamps can be used and switched
without the need for separate and expensive sockets.
Lamphouses need good
optics to transmit as much light as possible from the lamp being
used. Opti Quip has developed three different types of optics
for our lamphouses; one for general use, a quartz, and a special
type for multiple band pass fluorescence.
A third generation of
power supplies was introduced in 1992. The Model 1600 utilizes
the latest electronic technology in a high speed (30 KHz)
switching power supply. Ripple in output current, which equates
to ripple in light output, has been reduced to less than one
tenth of one percent. Stability has been greatly increased with
the added ability to maintain long-term light output by means of
light output feedback. Pulse power capability allows the
momentary increase of light up to a twenty times normal
illumination. A companion to the 1600 is the OQ Model 1700 power
supply. This model runs the XBO 250 watt arc lamp with the same
kind of ripple and stability. Each of these supplies weighs only
8 ½ pounds. The Model 1600 draws a mere 3 amps from a 110-volt
circuit.
Currently, advancements
in techniques for using fluorescence in genetics research have
created a need to switch easily among a variety of fluorescent
cubes and to do bright field work at the same time. This need
has led Opti Quip into developing these switching mechanisms and
the epi-illuminators that are used with them. |
