The OS37-CF/OS37-60CF Series infrared thermocouples
for high-emissivity targets (non-metals and coated
metals) and the OS38-CF/OS38-60CF Series for
low-emissivity targets (clean metals) feature an internal
screw that adjusts the 2% accuracy band anywhere
within the overall temperature range. All of these units
use a lens to produce a minimum spot at a focal point.
Models with 30° optics produce a rectangular minimum
spot size in the focal plane by using a masked detector.
Models with 1° (60:1) optics produce a more
conventional round minimum spot size at a focal point.
All models feature a built-in air purge.
