The instrument uses two types of light source lamps: D2 (deuterium) and WI (halogen).
The D2 lamp is used for ultraviolet region (185 nm to variable wavelength). The WI lamp is used for visible/near-infrared region (variable wavelength to 900 (1400) nm).
The closer the lamp service life comes to its end, the smaller the light intensity of each lamp, and the greater the noise in photometric data.

*The measurement for near infrared range (min. 900 nm) is possible only when using the integrating sphere attachment ISR-2600Plus (optional accessory).
« Lamp Replacement Procedure »
CAUTION:
• Before replacing the lamp, be sure to turn off the instrument power switch and remove the electric plug from the outlet.
Otherwise, fire, electric shock, or instrument malfunction may result.
Do not turn on the instrument power while the light source compartment is visually exposed. The generated ultraviolet ray may damage the eyes.
• Before replacing the lamp, turn off the instrument and let it stand at least for thirty minutes until the lamp cools down sufficiently.
Touching the lamp when it is still hot will burn you.
• Be careful not to break the lamp.
The broken pieces of glass may cause injury.
• Do not move the WI lamp to the right and left or up and down with it inserted into the socket.
The connection part between the pin at the bottom of the lamp and the glass may crack, which would disable the lamp to turn on.

NOTE:
• When removing and installing the light source compartment cover, avoid hitting the protrusion on the top of the D2 (deuterium) lamp against the back of the cover.
Doing so may cause a vacuum leak in the lamp tube.
• When replacing the lamp, wear cloth gloves so as not to leave fingerprints on the glass part.
Doing so may cause a vacuum leak in the lamp tube.
• When replacing the lamp, wear cloth gloves so as not to leave fingerprints on the glass part.
When the light source gets hot, a fingerprint will burn onto the bulb and light transmission will deteriorate.
• When replacing the WI (halogen) lamp, you may inadvertently touch the D2 lamp.
Cover the D2 lamp with a clean paper or cloth or remove the D2 lamp before replacing the WI lamp.
• When replacing the WI (halogen) lamp, you may inadvertently touch the D2 lamp.
Cover the D2 lamp with a clean paper or cloth or remove the D2 lamp before replacing the WI lamp.
1. Removing the Light Source Compartment Cover
1) Using a Philips screwdriver, loosen the fixing screw located on the side of the light source compartment cover.
2) Lift up the top of the fixing screw on the side of the light source compartment cover to release the cover notch from the fixing screw.
3) While lifting up the light source compartment cover at an angle, remove it from the main body.

2. Replace the WI (halogen) Lamp
When replacing the WI lamp, you may inadvertently touch the D2 lamp. Cover the D2 lamp with a clean paper or cloth or remove the D2 lamp before replacing the WI lamp.
1) Remove the WI lamp retainer spring from the top of the WI lamp.

2) Pull out the WI lamp from the socket.

3) Wearing cloth gloves, hold the new WI lamp at the top and bottom so as not to taint its beam port.
4) Insert the new WI lamp into the socket. Push it forward until the tips of the two pins on the WI lamp contact the back of the socket and stop.

NOTE: WI lamp pins do not have a polarity. There is no problem inserting it from any direction.

5) Return the WI lamp retainer spring, removed in step 1, to the original position.
6) Reinstall the D2 lamp to the original position.
Be sure that no paper or cloth used for the work is left in the light source compartment.
Be sure that no paper or cloth used for the work is left in the light source compartment.
7) Reinstall the light source compartment cover in opposite order (see also "Removing the Light Source Compartment Cover").
8) Insert the electric plug into the outlet, and switch on the instrument. (Press the "|" side on the switch.)
The initialization starts.
The initialization starts.
9) Run LabSolutions UV-Vis and connect all related instruments to check that all initialization items are complete.
10) Complete the initialization and reset the cumulative lighting time of the WI lamp on the [Maintenance] window of LabSolutions UV-Vis.
3. Replacing the D2 Lamp
1) Wearing cloth gloves, hold the resin part of the D2 lamp, and slowly pull it straight up.
2) Slowly extract the D2 lamp upward to remove it from the socket.
2) Slowly extract the D2 lamp upward to remove it from the socket.

3) Insert the new D2 lamp into the socket.
At this time, fit the locating lug at the bottom of the D2 lamp to the socket notch.
Confirm if the D2 lamp is fully inserted into the socket.
