Our survey of IC348 in the near-infrared wavelength JHK
-bands
reveals many properties of the cluster. We performed photometry on
117 stars in each of the wavelength bands. The apparent magnitudes of
our stars ranged from about 7.5 to 14.5 magnitudes in the H-band.
This shows a wide range of main sequence stars of different spectral
types. The color-magnitude and color-color diagrams for our cluster
showed a significant amount of reddening in our cluster. Comparing
these to the control field, we see that this reddening is most likely
due to the interstellar dust found within our cluster as there is
significantly less reddening in our control field. We determined the
average extinction in the K-band to be about 0.5 magnitudes which
corresponds to a visual extinction of about 8.929 magnitudes of
extinction. Most of the stars found in our cluster were determined to
be main sequence stars as they fell within the normal reddening region
on the color-color diagram. About 15% of the stars in our cluster
are possible T Tauri or proto-stars. We determined the age of the
cluster to be about
years old by comparing our
luminosity function to the model luminosity function and the dimmest
star observed in our cluster was found to have a mass of
0.25M
-0.47M
