3.0. Components Description
3.1. Housing
The MK III housing is made of stainless steel, making the equipment suitable for clean
room operations and allowing for easy cleaning. The housing consists of 3 main sections:
1. Chassis - The vertical design allows for more efficient use of counter-top space. The
optical assembly is located in the upper compartment. The top cover is secured by
loosening four quarter-turn, captive, Phillips head fasteners. The power supply and all
the controls and accessories are located in the bottom housing.
2. Lamp Housing - The top cover is secured by four quarter-turn, captive Phillips head
fasteners. Removing it allows access to the bulb, reflector, and the IR filter
assemblies.
3. Bottom Cabinet – The bottom side cover is fastened by six Allen head screws.
Removing it allows access to the power supply for voltage setting. There are no
serviceable parts inside.
The housing compartment features a recessed rear panel with air vents on the top and
sides. These vents provide air access to the cooling fans even if the MK III is operated
while pushed all the way against a wall.
