PRECAUTIONS
WARNING!
LIFE SUPPORT APPLICATIONS POLICY
MegaPlus cameras are not authorized for and should not be used within life support
systems without the specific written consent of Redlake MASD, Inc.
NON-CRITICAL MEDICAL APPLICATIONS
MegaPlus cameras must be grounded to building earth ground while operating. This
camera has passed IEC 601 class B standards.
The voltage drop on the camera’s power return line must be less than 0.5 Volts DC.
Use a heavier gauge power cable to reduce the voltage drop below 0.5 Volts DC. Fo
r
medical applications, any power supply connected to the camera must meet IEC 601
specifications.
CAUTION:
A
laser beam focused on the sensor, either directly or by reflection, can cause
permanent damage to the sensor. Any laser powerful enough to produce
localized heating at the surface of the sensor will cause damage, even if the
camera power is off. A sensor damaged by laser light is NOT covered by the
warranty.
OPERATING TEMPERATURE
The MegaPlus camera is designed to operate satisfactorily in an environment where the ambient
temperature is between 0° and 35°C (32° and 95°F), with no water condensation present.
STORAGE TEMPERATURE
Do not store the equipment in an area where the temperature will drop below –25°C (-13°F) or
exceed 80°C (176°F). Do not allow moisture to condense on the system.
SHIPPING
When shipping, use a carton that protects the camera from shock and moisture, similar to the
carton in which the unit was originally delivered. Do not ship the equipment in a cargo area
where the temperature will drop below -25°C (-13°F) or exceed 80°C (176°F). Do not allow
moisture to condense on the system.

1. INTRODUCTION
1.1 Introduction
The MegaPlus Camera is a high-resolution solid-state camera designed for scientific and
industrial imaging applications. The system consists of a DC powered Camera Head with a 68
pin digital interface. There are no manual user controls on the camera, however the camera is
operated by commands sent through a serial communication link. The Camera works with either
an RS232 or RS422 serial communications command input.
The operation of the MegaPlus Camera is very similar to the operation of a 35mm film camera. In
a film camera, the film is exposed by opening the shutter for a specific amount of time. The
shutter then closes and the film is advanced to the next frame. In the MegaPlus Camera, a built-
in electromechanical shutter is used the same way. The shutter opens exposing the sensor, and
then closes while the image captured by the sensor is sent to a frame store device. The shutter
in the MegaPlus Camera can be controlled internally or externally.
The Camera Head features a high-resolution Charge-Coupled-Device (CCD) array containing
1,317 (H) x 1,035 (V) light sensitive elements (pixels). These pixels are 6.8 microns square and
have a center-to-center spacing of 6.8 microns (100% fill ratio). Using a high quality lens with the
MegaPlus Camera will produce the best possible resolution.
The equal horizontal and vertical geometry simplify measurements taken with the camera. The
benefit of having a 100% fill ratio is reduced aliasing, improved subpixel accuracy, and a 100%
light sensitive area. The Camera output has an 8-bit digital video output containing 256 levels of
gray for each pixel. Exposure is adjustable from 1 millisecond to 100 seconds in 1-millisecond
increments using the internal exposure control. Exposure times from 1 millisecond to the longest
time practical can be had by using an external exposure control signal.
The camera can be triggered asynchronously to capture high-speed events. Separate exposure
and readout cycles can be achieved by using a pulsed illumination light source such as a strobe.
An external strobe flash unit can be synchronized through a BNC connector on the rear panel of
the camera. This dramatically improves picture quality when the object being photographed is in
motion.
The MegaPlus Camera is ruggedly designed and can accommodate moderate amounts of shock
and vibration. Gaskets protect the camera’s interior components from dust, contaminants and
EMI.
