Chapter 1

Setup and Operation

Overview

The SpectroClip probe is designed to measure thin materials such as leaves and other thin samples in the
field. Transmission, reflection and absorbance can be measured on materials with a maximum thickness
of 5 mm. SpectroClip features specially designed integrating spheres that function as collection probes
and can be connected to any Ocean Optics spectrometer to acquire data. The top integrating sphere also
includes an input port for a fiber-coupled light source to illuminate your sample. SpectroClip's integrating
spheres capture diffuse reflected or transmitted light more efficiently than lens-based collection optics.

Jaz-SpectroClip-TR

SpectroClip can support wavelength ranges from 200-2500 nm -- depending on which light source, fiber
(UV-VIS or VIS-NIR) or spectrometer configuration you use. The active illuminated area is 5 mm.

SpectroClip Models

SpectroClip includes the following models:

Unpacking SpectroClip

The following sections provide instructions on unpacking and setting up your SpectroClip.
Before using the SpectroClip for the first time, check for transport damage. Be sure to adhere to all

warnings on the unit and in this manual.

Procedure

►

1. Unpack your SpectroClip device carefully.

2. Inspect the outside of the instrument and make sure that there is no damage. Do not use the
instrument if damage is present.

3. Detach the outer side of the fiber protection and inspect the SMA connectors. Do not use the
instrument if damage is present.

1: Setup and Operation

Package Contents

Your SpectroClip package should contain the following:

 SpectroClip device (plus Jaz spectrometer for Jaz-SpectroClip-TR)
 Black and white reference device
 Spiral coiled tube 1.5 meters long (for fiber protection)
 Hexagonal socket screw keys SW 2.5 mm and SW 1.3 mm

SpectroClip Parts

For optimal optical measurements, take care that no objects or liquids enter into the integrating spheres.
To do this, use protection caps on open SMA connectors, and keep the gripper closed while not using the
SpectroClip. In addition, keep the reference clean and undamaged for best reference measurements.

1: Setup and Operation

Using SpectroClip

The procedure for using your SpectroClip differs, depending on which model you have.

Using SpectroClip-R

► Procedure

1. Unscrew one part of the fiber cover.

2. Slip the spiral coiled tubes over the fibers.

3. Connect the two fibers to the SMA connectors. You shouldn’t use a fiber thicker than 400 µm on
the focusable SMA connector from the picture above.

4. Assemble the fiber cover and tighten the three screws. The spiral coiled tube should begin inside
the fiber cover.

5. To record a dark spectrum use the black/ white reference with the black side turned to the
reflectance sphere.

6. To record a reference spectrum use the black/ white reference with the white side turned to the
reflectance sphere.

7. Clamp your measuring object into your SpectroClip and start the measurement.

Caution

For mechanical reasons, you can use samples with a height of up to 15 mm only.

Avoid stray light. During your measurement there should be no light bypassing
your sample.

Using SpectroClip-TR

1. Unscrew one part of the fiber cover.

2. Slip the spiral coiled tubes over the fibers.

3. Connect three fibers to the SMA connectors. If you don’t use all SMA connectors cover the
empty connector with a protection cap.

1: Setup and Operation

4. Assemble the fiber cover and tighten the three screws. The spiral coiled tube should begin inside
the fiber cover.

5. To record a dark spectrum, use the black/ white reference with the black side turned to the
reflectance sphere.

6. To record a reference spectrum use your SpectroClip without any object between the clamps.

7. Clamp your measuring object into your SpectroClip and start the measurement.

Caution

Don’t use samples thicker than 5 mm. With thicker samples, the amount of
unwanted stray light increases.

Transmission Measurement Loss of Intensity

It is recommended to use the same distance between integrating spheres to measure the reference spectra
as was used for the sample measurement. The loss of intensity for a port difference of 1 mm is 3 %
@620 nm with respect to zero difference. Other losses of intensity for the reference spectra are shown in
the table below.

Fiber and Diameter Distances (Valid for Optical Alignment)

Fiber Diameter (µm) Maximum Port Difference Loss in Reference Spectrum (relative to 0 distance)

100 8 10%

400 4 10%

Adjustment of the 8° Coupling Port

You can adjust the focus of the light beam between the upper fiber and the opening of the reflectance
sphere.

►

Procedure

To adjust the focus,

1. Loosen the screw on the SMA connector (#7 in SpectroClip Parts
key (SW 1.3 mm).

2. Move the SMA connector for optical performance.

3. Block the screw after adjustment.
