Global Laser Lyte-MV 2 User manual

Thank you for purchasing the Lyte-MV 2 laser diode module. This module emits a spot, line or
pattern in the visible or infrared wavelength range.
If you have any queries or require help when using the Lyte-MV 2 Range please call us on
[phone] or contact your local representative.
The Lyte-MV 2 provides a reliable industrial light source for a wide range of machine vision ap-
plications including triangulation, 3D inspection and alignment. It features IP67 protection, a
threaded barrel and the ability to operate from industrial voltage sources such as 24Vdc while
still providing market leading modulation features.
Available with powers up to 120mW in Red and Blue and 200mW in IR. An array of optical op-
tions including circular and elliptical spots, uniform lines and diractive patterns. The Lyte-MV 2
also has a user adjustable focus control, to allow the user to optimize the focus via an external
control ring. The threaded barrel allows the user to mount the laser to bulkheads and mounting
blocks while ensuring heat sinking. This M18 threaded barrel makes it compatible with the ma-
jority of existing machine vision systems. The modulation options allow the user to synchronize
the output or control the power output via TTL.
A comprehensive range of accessories including mounting
clamps and rail systems, mains power supplies and laser
safety and enhancement glass are also available to
complement the Lyte-MV 2.

2. Product Operation
A: CW Mode
To operate laser in CW mode the Red ,Black, Yellow & Blue leads should be connected to the
following:
(Warning do not apply voltages greater then 5.5Vdc to the Blue enable lead or permanent
damage will accrue to the laser module. See section C for further detail).
Pin Lead Description Lyte-MV 2
1Red Lead + Volts +5 to 30Vdc
2Black Lead 0 Volts 0 Vdc
3Yellow Lead Modulation + Vdc
4Blue Lead Enable Leave unconnected if not being used as enable switch
B: TTL Mode
The Lyte MV 2 allows the unit to be gated on and o, or pulse-width modulated at TTL voltage
levels via the yellow control lead. A TTL high level signal turns the laser on and a TTL low level
signal turns the laser o. Frequency bandwidth is typically 500KHz. Rise Time: <0.5 μs (typical).
C. Blue Lead (Enable Switch)
An on/o switch function is available via the blue wire, which is particularly useful for safety
interlocks or enable switch’s required for laser safety systems. Applying 0V will switch the laser
o whilst applying V supply up to 5.5Vdc leaves the laser on. Do not apply a voltage higher
then 5.5Vdc or permanent damage will accrue to the laser module.
Pin Lead Description Lyte-MV 2
1Red Lead + Volts +5 to 30Vdc
2Black Lead 0 Volts 0 Vdc
3Yellow Lead Modulation Input TTL Signal
4Blue Lead Enable Leave unconnected if not being used as enable switch

D. Operating with a PS-1 5 Volt
If you have purchased a Lyte-MV 2 with a 100V/240V to 5Volt PS1 you will have the following
items:
Lyte-MV 2 Laser
Lyte-MV2 to PS-1 Cable
100V/240V to 5 Volt PS-1
Main socket to PS-1 Power Lead (UK, Euro or US)
1. Connect the DC jack on the Lyte MV 2 to PS1 cable into the DC socket on the PS-1 power
supply and screw binder connector into the connector on the end of laser.
2. Connect IEC plug to PS-1 power adaptor.
3. Plug the mains plug into a mains socket.
4. Switch on the power supply via key switch (If you have purchased a 5V PS1 tted with a key
switch) or switch on at the mains socket.

To ensure the lifetime and the stability of the laser it is recommended that it is mounted in a
suitable heat sink/mount. The case temperature should be kept within the specied range at
all times, failure to do this could result in shortened lifetime or catastrophic failure. As a guide,
laser diode lifetime decreases by a factor of two (approx.) for every ten degree increase in
operating temperature.
To assist with this requirement the Lyte-MV 2 has a threaded front barrel (M18x1) which can
t to a bulkhead or threaded hole. The direct contact of the barrel to the mount helps to
ensure heat sinking and improve laser diode lifetime. Alternatively a version of Global Laser’s
heavy duty clamp which has a thread arm is available. To further assist mounting the module
is supplied with two nut’s which are tted to the front barrel. A tool to t a 24mm nut is required
for adjustment. To further improve reliability the barrel is isolated from the laser diode supply
voltage at all times.
3A Mounting the Lyte-MV 2 in the Heavy Duty Clamp
1. Un-tighten allen screw A (see drawing B) with the supplied allen key
2. Screw the laser into the mounting hole (see drawing B) and tighten allen key A.
3. For vertical adjustment of the laser un-tighten grub screw A (see drawing B). This will allow
the section mounting the laser to be adjusted. When the vertical posting is complete re-
tighten grub screw A.
4. For horizontal adjustment of the laser un-tighten grub screw B (see drawing B). This will
allow the main body of the mount to be moved. When the horizontal positing is complete re-
tighten grub screw B.
5. To secure the heavy duty clamp to a surface machine screw or studs can be used in
conjunction with the base section (see drawing B for thread details).
3B Mounting the Lyte-MV 2 in the Heavy Duty Clamp with the Magnetic Base
1. Un-tighten allen screw A (see drawing B) with the supplied allen key
2. Screw the laser into the mounting hole (see drawing B) and tighten allen key A.
3. For vertical adjustment of the laser un-tighten grub screw A (see drawing B). This will allow
the section mounting the laser to be adjusted. When the vertical posting is complete re-
tighten grub screw A.
4. For horizontal adjustment of the laser un-tighten grub screw B (see drawing B). This will
allow the main body of the mount to be moved. When the horizontal positing is complete re-
tighten grub screw B.
5. To secure the magnetic base to the heavy duty clamp simple screw the stud on the top of
the magnetic base into the centre hole in the base of the heavy duty clamp until tight.
6. Remove the keeper from the magnetic base and place on a ferrous surface to secure.
3. Mounting

5. Focus Adjustment
4. Cleaning The Optics
The laser will have been focused and tested at the nominal working distance requested at
the time of order. If you did not specify a distance or were unsure at the time of order it will be
focused at 300mm (11.81 inches).
Should you need to adjust the focus (alter the spot size line thickness/pattern thickness)
please follow the simple instructions below:
Turn the focusing control (brass knurled section) at the middle of the laser (see diagram A)
clockwise / anti clockwise until the desired focus is achieved. As a rule of thumb if you wish
the focus to be at shorter distance from the laser than it is currently set to turn the focus
control anti-clockwise. If you wish the focus to be at longer distance from the laser then it is
currently set to turn the focus control clockwise.
The Lyte MV 2 is protected against dust and uid with an ingress protection (IP) rating of 67.
The protection level is dened IEC60529 as below:
Please Note that liquids are dened as water. Oil or chemicals may require further
protection.
It is recommended that when the Lyte-MV 2 is not in use the supplied protective cap is
placed over the optics to reduce the risk of the being contaminate by dirt.
If the laser pattern becomes fuzzy or unclear, please check the following:
1. Check the laser is in focus (see section 5).
2. Verify the protective window on the front of the laser is clean
If the window is contaminated, the lens can be cleaned with an optical cloth or cleaning kit.
IP First Number Protection against solid objects
6Totally protected against dust
IP Second Number Protection against liquids
7Protected against the eects of immersion between 15cm and 1 meter
