Our Olympus BX51 light source is bright in the center of our spcimen and then darkens as the field moves out of the center. We can not get the same amount of light to cover our whole specimen.

This may sound redundant but, did you check out the onscreen munu, and go to " troubleshooting " ? If that doesn't help call the manufacturer of the TV.
Yes...within a range. The display will automatically lighten and darken depending on the amount of light in the room. During the day or when there are bright lights in the room, the display will go to full brightness. When the lights go off or the room is otherwise darkened, the display will shift down to a lower brightness. You can make the "lower brightness" a bit brighter by holding down the CLOCK SET button and pressing the 'volume up' button.
Darken the screen and either move the lid forward or backwards. Laptops have Liquid Crystal Screens and moving the lid backwards or forward will give the screen a different look.
If you need to adjust the brightness of the screen it is controlled by keys on your laptop. Most times to darken the screen you will have to hit the FN, CTRL or ALT key and hold it down while you hit the key that corresponds to the screen darken key. On some computers (even on my laptop) it will be the down arrow key, so i would press FN+the down arrow key. Remember to hold the first key down while you hit the next key. The icon used for most times to denote the brightness or darkness looks like a circular sun or a washer that goes on screws.
Yes I believe I fixed my problem. I shined a bright flash light at
the light sensing photocell and took pictures with it (no flash).
Then I darkened it, took pictures (it flashed). I did this back and
fourth and it seemed to work although I have not tried it in the
field yet. Thanks for your offer of help and I do think your
rates are reasonable.

It does sound like a light leak, but hopefully all that has happened is that the foam seals surrounding the film compartment have perished and need replacing. With luck, this is unlikely to be expensive - check with your local camera shop or second hand camera dealer.
Set the metering mode to Partial Metering. This uses only 9% of the field of view, centered around the middle square in the viewfinder, as the subject area. If you still find it too bright, try changing the exposure compensation a couple of clicks.
I wish you have explained more about what you mean by close-ups.
If you are talking about portraits:
...avoid flash - use some type of dim portable lamps
...use the optical zoom set to about 2X
.....move back and reframe the subject
...set the camera to "aperture priority" and
.....select f2.8 (to blur the background)
If you are talking about table top photography:
...avoid flash - use some type of bright
.....portable lamps
...use a tripod
...set the camera to shutter priority and select a
.....slow shutter speed (to increase depth of field)
...focus on the exact spot you want to be sharpest
