Chapter 3 Description

This compact, handheld fiber-coupled laser source (measuring only 5.33″ x 2.74″ x 0.94″) is intended to be used as a portable alignment laser though it is well suited for any task requiring a fiber coupled red laser. The laser output of the HLS635 may be set in 3 modes: low power (~1 mW), high power (≥2.5 mW), and a pulse mode that switches the laser from high power to off at 2 Hz. The selected mode is indicated by indicator lights on the front panel of the HLS635. The output is FC/PC coupled using the standard LPS-635 pigtail without the aluminum cover. The unit includes an internal 3.6 V NiMH rechargeable battery and charger. A red rubber cover boot with a kickstand is also included. This boot may be removed if desired.
The DC power supply is a universal type and will work with line voltages between 100 and 240 VAC from 50 to 60 Hz @ +/- 10%.Connect the appropriate adapter for the wall plug style after removing the temporary spacer. Connect the 2.1 mm plug to the front of the HLS635 if charging is needed.

Chapter 4 Setup ATTENTION!

ATTENTION!
The battery does not arrive fully charged, but may have some residual charge. It should not be used until it is fully charged. Follow the instructions below for  initial charging instructions.

Initial Battery Charge
Before using the HLS laser source cordlessly, the battery must be fully charged. The unit may be plugged in and used with the included power supply, but the battery will not charge while the unit is in operation.

1. Make sure the adapter for your local mains power is properly installed and seated onto the power supply.
2. Plug the power supply into the mains outlet.
3. Plug the power supply into the handheld laser.
4. A green LED will light next to the word Charging on the front of the unit.
5. When the device is fully charged, the LED will turn off.

Quick Start Information
The HLS635 can be used right out of the box safely, but it must be connected to the AC mains during use. In addition, the battery will not charge while the device is powered on and enabled. See the operating instructions on the follow page for more information.

1. Make sure the adapter for your local mains power is properly installed and seated onto the power supply.
2. Plug the power supply into the mains outlet.
3. Plug the power supply into the handheld laser.

Chapter 5 Operation

Turning on the Source
The HLS635 can be used right out of the box safely, but it must be connected to an AC outlet during use. Also, the battery will not charge while the device is powered on and enabled.
The operation of the HLS is the same for power and cordless operation.

1. Remove the dust cap from the connector, clean the connector on an FC/PC fiber patch cable, and insert it into the connector on the HSL.
2. Depress the Power/Enable button until the Power LED and one of the Mode Indicator LEDs light, about 3 seconds.
3. Select the desired mode by briefly depressing the Mode button. The three modes will cycle from Low, High, and a 2 Hz flashing mode
4. Momentarily press the Power/Enable button to enable the laser.
   The Laser On indicator will light when the button is pressed and the laser output will come on after a 2 second delay.

Adjusting the Laser Output Power
Pressing the Mode button will cycle through the three laser power settings:

• Low power is approximately 1 mW,
•  High power is greater than 2.5 mW but not more than 5 mW, and
• Pulse mode will flash the laser on and off at the High power value at 2 Hz.

Turning the Laser Off
Momentarily press the Power/Enable button to disable the laser, but keep the unit powered on. The Laser On indicator will go out and the laser will be disabled. Note that in this mode, the laser will not charge. The HLS635 can be put into standby by holding the Power/Enable button for approximately 3 seconds. The HLS635 is in standby when the Power indicator is not lit. Standby should be used whenever possible maximize battery life if running on battery power.

Charging the Unit
When starting from a completely drained battery, the unit takes about 1 to 1.5 hours to charge during that time, the green Charging LED will light. At the end of the charge cycle the LED will turn off. The unit can be left on the charger indefinitely to maintain the full charge. Periodically, the Charging LED may flash indicating that the unit is “topping off” the battery.
The rechargeable battery will slowly discharge over time even when not in use. To prevent this, it is safe to leave the unit plugged into the power adapter and allow the unit to self-charge periodically.
The HLS635 is powered by the DC connector any time it is attached. Battery power is only used when the DC connector is removed. DC power may be connected and disconnected while the HLS635 is being used without interruption.

Battery Discharging
The Power LED indicator will start to flash when the battery is low. After a period of time, if power is not reconnected or the unit turned off, the unit will turn off and the battery will be disconnected from all internal circuitry to prevent battery damage. The power adapter can be plugged in to continue use or charge the unit normally.

Chapter 9 Regulatory

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the European Community and the corresponding national laws, Thorlabs offers all end users in the EC the possibility to return “end of life” units without incurring disposal charges.

• This offer is valid for Thorlabs electrical and electronic equipment:

• Sold after August 13, 2005

• Marked correspondingly with the crossed out “wheelie bin” logo (see right)

• Sold to a company or institute within the EC

• Currently owned by a company or institute within the EC

• Still complete, not disassembled and not contaminated
  As the WEEE directive applies to self-contained operational electrical and electronic products, this end of life take back service does not refer to other Thorlabs products, such as:

• Pure OEM products, that means assemblies to be built into a unit by the user (e.g. OEM laser driver cards)

• Components

• Mechanics and optics

• Left over parts of units disassembled by the user (PCB’s, housings etc.).

If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs or your nearest dealer for further information.

Waste Treatment is Your Own Responsibility
If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.

Ecological Background
It is well known that WEEE pollutes the environment by releasing toxic products during decomposition. The aim of the European RoHS directive is to reduce the content of toxic substances in electronic products in the future.
The intent of the WEEE directive is to enforce the recycling of WEEE. Controlled recycling of end-of-life products will thereby avoid negative impacts on the environment.
