General Operating Procedures
The following sections present some guidelines for operating the OMM-6810B
with the OMH-6727B. More detailed instructions are found in the OMM-6810B
Instruction Manual. Remote operation is discussed in Chapter 4.
Warm-up and Environmental Considerations
The main unit and Optical Measurement Head should operate at an ambient
temperature between 10 and 35
°
C and a relative humidity less than 70%.
Storage temperatures should be between -40 and +70
°
C, To achieve rated
stability, let both devices warm up for at least one hour.
Beam Alignment Considerations
The OMH-6727B is designed to provide a simple operating format. The beam
from the source should be directed perpendicular to the face of the 6727B and
directly into its aperture. Be sure the entrance angle does not exceed the
specified
±
10
°
from perpendicular.
Be aware that certain lasers emit a significant amount of non-lasing radiation.
This radiation can cause erroneous measurements if the source is placed too
close to the measurement head. The innovative ILX Optical Measurement Head
offers easy access for many different source types:
