Thank you for purchasing the LDM125. This emits a green, red or infrared dot. If you have any problems or require help when using the LDM125 please call us on +44 (0)1495 212213 or contact your local representative. The LDM125 is an 11mm diameter laser diode module with a 25mm mounting flange with two threaded holes to assist in mounting and alignment. The mounting flange also provides a greater surface area for improved heat sinking of the module. Available in wavelengths of 520, 635, 650, 670, 780 & 850nm with power up to 5mW as standard. It requires an operating voltage of 5Vdc (red and infrared models) or 10Vdc (green models) and features an electrically isolated body. As a further enhancement the LDM125 can be fitted with a TTL modulation input with a bandwidth up to 100Khz. A choice of two collimating lens are offered. The “G” model uses a glass lens with an elliptical output beam, whilst the “P” model uses a plastic lens which produces a circular output beam with a lower beam divergence. Both models have user adjustable focus. A range of accessories such as mounting clamp are also available. Product Overview LDM125 Userguide

Product Overview
LDM125 Userguide
Product OperationThe LDM125 is available in two variants, a CW model fitted with two input wires or a model with a TTL enable which is fitted with three wires.
A. CW ModelTo operate laser in CW mode the Red & Black leads should be connected to the following:
Focus Adjustment
B: LLM125 with TTL ModulationA common requirement for applications which use photo detectors, cameras and other non-visual sensing is the ability to rapidly switch the laser output ON and OFF. Simply applying and removing the supply voltage is rarely satisfactory and in certain cases can result in diode failure. This is because laser diodes are very sensitive to voltage spikes and surges that are often the result of uncontrolled supply switching.
To overcome this limitation the LDM125 can be installed with a third input wire that enables reliable and predictable laser TTL modulation. A logic LOW level turns the output completely OFF. However, applying logic HIGH turns the laser ON after a control input delay. This sets the maximum rate at which the module can switch fully ON and OFF.
To operate the laser connect the input wires in the below configuration:
The focus of the LDM125 can adjusted by one of two method depending on model.
If you have an LDM125G Model (see drawing A) follow the method below:1. Insert focus key (see drawing C) into laser barrel and align with focus control groves.2. Turn the focus key until desired focus is achieved.
If you have an LDM125P Model (see drawing B) follow the method below.1. Taking care not to touch the lens itself, grip the forward section of the laser.2. Turn until the beam is the desired size.

Cleaning The OpticsIf the laser pattern becomes fuzzy or unclear, please check the following: 1. Check the laser is in focus.2. Verify the optical lens is clean, if the area has been contaminated please remove dirt with dry air.
Safety & ClassificationThese modules are intended for incorporation into customer equipment. They are classified in accordance with IEC60825-1: 2014, which should be consulted prior to designing or using any laser product. The following labels are supplied for attachment to the customer’s equipment, but responsibility for compliance with the standard remains with the user.

Mounting & HeatsinkingThe lifetime and stability of your laser can be optimised when mounted on a suitable heat sink. This allows the case temperature to be kept within its specified range. Failure to properly heat sink your laser device could result in shortened lifetime or failure of the diode. As a general guideline, the lifetime of a laser diode decreases by a factor of two (approx.) for every 10°C increase in operating temperature.
There are three mounting clamps available for the LDM125: heavy duty clamp (with/without mag-netic base), MK1 mounting kit, and swivel clamp.
Mounting the LDM125 in the Heavy Duty Clamp (See drawing D)1. Secure the clamp to a surface. There are two methods:a. Screw an M5 stud to the bottom of the base, orb. Remove the base by removing 2 x grub screw B with the supplied Allen key, then thread anM5 cap screw through the top of the base. Then re-attach the base to the body of the clamp.2. Loosen Allen screw A with the supplied Allen key3. Slide your laser into the mounting hole and then tighten Allen screw A4. Loosen grub screw A5. Adjust the vertical angle of your laser and then tighten grub screw A6. Loosen 2 x grub screw B. This will allow the main body of the mount to be rotated independently of the base7. Adjust the horizontal angle of your laser and then tighten 2 x grub screw B
Mounting the LDM125 in the Heavy Duty Clamp with Magnetic Base (See drawing D & E)1. Secure the magnetic base to the Heavy Duty Clampa. Screw the stud on the top of the magnetic base into the centre hole at the bottom of the Heavy Duty Clamp2. Remove the keeper from the magnetic base and place on a ferrous surface3. Loosen Allen screw A with the supplied Allen key4. Slide your laser into the mounting hole and then tighten Allen screw A5. Loosen grub screw A6. Adjust the vertical angle of your laser and then tighten grub screw A7. Loosen 2 x grub screw B. This will allow the main body of the mount to be rotated independently of the base8. Adjust the horizontal angle of your laser and then tighten 2 x grub screw B
Mounting the LDM125 in the MK1 Mounting Kit (See Drawing F)1. Attach components as in drawing D 2. Loosen machine screw A with M3 Allen key 3. Set the length of the mounting post 4. Secure the clamp to a surface using machine screw A (M5 x 25 & M5 x 35 machine screws Mounting two M5 hex nuts & washers are supplied)
5. Tighten machine screw A with an M3 Allen key 6. Loosen Phillips screw A with a Phillips head screwdriver 7. Slide the laser into the mounting hole 8. Rotate the mounting clamp to the desired position and then tighten Phillips screw A
Mounting the LDM125 in the Swivel Mounting Clamp (See drawing G)1. Secure the mounting base to a surfacea. You can use 2 x Ø9 mm slots, 4 x Ø4.5 mm holes, and/or 2 x Ø3.5 mm countersunk holes to ahieve this. If mounting via Ø3.5mm countersunk holes, the swivel bracket must be removed from the base and then reattached after mounting.2. Loosen A llen screw A (M3)3. Slide your laser into the mounting hole and then tighten Allen screw A4. Loosen Allen screw B ( M5)5. Adjust tilt angle and then tighten Allen screw B6. Loosen 2 x M4 screws attaching swivel bracket to base7. Adjust swivel angle and then tighten 2 x M4 screws
