T300-RT-UV-VIS Transmission Dip Probe

The T300-RT-UV-VIS Transmission Dip Probe couples to our

spectrometers and light sources to create small-footprint optical-sensing

systems for measuring in situ transmission in chemical solutions and other

liquids. The standard T300-RT-UV/VIS Transmission Dip Probe has (2)

300 mm diameter solarization-resistant fibers (1 illumination, 1 read), in a

5.0" x 0.25" OD stainless steel ferrule. Screw-on, interchangeable probe

tips, in path lengths of 2 mm, 5 mm, or 10 mm, are available to configure

your system for either optically dense or dilute solutions.

Caution:

• Handle the probe with care. Dropping the probe may cause

permanent damage.

• Bubbles in the sample will interfere with your readings. Regularly

inspect the sample region for bubbles.

Overview

The T300 consists of two identical fibers in a bifurcated assembly. A plano-convex lens shapes the light coming

out of the illumination fiber. The light is transmitted through the sample, reflected off the mirror, interacts with the

sample again, and transmitted back through the probe via the read fiber. Because the light travels through the

sampling region twice, the optical path length is actually twice the length of the sample aperture. The transmission

cell is used to measure absorbance of the fluid that fills the sample compartment between the fibers and the

mirror, which is a UV-enhanced aluminum, second-surface mirror.

Operation

1. Connect one leg of the probe to the light source, and then connect the other leg to the spectrometer. It

does not matter which leg of the probe you connect to the light source or spectrometer.

2. Screw the appropriate probe tip for the experiment onto the end of the probe.

Note: To replace the probe tip, unscrew the probe tip and screw in the 2 mm, 4 mm, or 10 mm

replaceable tip.

3. Prepare the sample.

4. Place the probe tip in the sample and adjust the integration time in OOIBase32 to obtain a signal of

~3500 counts while in scope mode.

5. Minimize the light reflecting from the backside of the sleeve lens by optimizing the back-reflection of the

probe. Optimize the back-reflection of the probe as follows:

a. Remove the tip from the probe.

b. Immerse the probe in a large container of water with a dark background (such as a black plastic

bucket or a beaker enclosed in a dark cloth). When the light source is on and the probe is in this

state, only light from the back surface of the lens in the probe sleeve should be reflected back into

the detection fiber. The spectrum displayed in OOIBase32 should be relatively smooth, and will

increase or decrease in intensity as you move the probe in and out of the sleeve.
