AR-1 Argon

Calibration Light Source

Installation and Operation Instructions

Description

The AR-1 Argon Calibration Source is a wavelength calibration source for UV-VIS-Shortwave NIR
spectrophotometric systems. The AR-1 produces Argon lines from 696-1704 nm, and is an ideal lamp
to use when performing fast, accurate spectrometer wavelength calibrations in the NIR range.

The AR-1 features an SMA 905 Connector for interfacing with our optical fibers. It operates with a 12
VDC power supply (included with the unit) or 9V battery (not included).

The following sections detail the features of the AR-1 Argon Calibration Light Sources.

AR-1 Argon Calibration Light Source

Note

The AR-1 is NOT designed to operate as an excitation source in your experiments.
Spectral lines above 922 nm are not easily detectable by Ocean Optics spectrometers.

AR-1-CAL Installation and Operation Instructions

Parts Included

The AR-1 package includes the following items:

 AR-1 Argon Calibration Light Source

 12 VDC power supply

WARNING

The beam emerging from the light source contains UV radiation that can cause
serious eye injury upon direct contact with the eye. Never look directly into the
light source.

The SMA 905 Connector may get extremely hot during operation. After lamp
use, allow sufficient time to cool before handling.

Dangerous voltages are present, and there are no user-serviceable parts inside.
Never open the AR-1.

Additional Accessories

The following are additional accessories available from Ocean Optics that you may need, depending
on your system set-up:

 Spectrometer

 SMA-terminated optical fiber

 Ocean Optics software

Connecting the AR-1

Follow the steps below to set up your AR-1 for use.

► Procedure

1. Plug the 12 VDC power supply into a power outlet, then connect the barrel connector of the
power supply to the power input on the rear of the AR-1.

or

Alternately, you can use a 9-volt battery (not included) to power the AR-1. Open the battery
hatch of the AR-1 and install the 9-volt battery, and then proceed to Step 2.

2. Connect a fiber to the SMA 905 Connector on the AR-1. If your spectrometer does not have
an entrance slit, use a 50
reduced optical resolution.
