Any part or specification of each module can be modified.

We divide a laser diode module structure into 4 main sections:

- a laser diode
- an optical lens
- a laser driver circuit
- optical and mechanical properties

1. Laser diode:

-Main characteristics of laser diode: wavelength, output power, and operating temperature

We can provide diode laser modules with wavelengths comprising 405nm, 450nm blue laser module, 520nm green laser module,

635nm, 650nm red laser module up to 1550nm infrared laser module and a laser module driving power can be equal or smaller

than its laser diode operating power (as stated on the corresponding laser diode data-sheet)

2. Optical Lens:

The following are the basic optical specifications that we need to agree upon before starting any laser module production.

- Main characteristics for the beam collimation: divergence angle, laser spot size

- Choice of the laser pattern: laser dot, laser line, laser cross line, or any kind of laser pattern achieved through using DOE

  (Diffractive optical elements).

Spot size:  The laser spot size has a direct relationship to the distance of projection. If you can define the operating distance 

of your laser, the we will adjust the focus of the optical collimating lens to meet your application requirements. 

3. Laser Driver Circuit:

The driving circuit of the laser modules can be either APC (Auto Power Control) or ACC (Auto Current Control).

An APC driver controlled laser module will automatically adjust the input current in order to output a constant value of optical power.

An ACC driver controlled laser module will in another way have a constant value of input current, while the output power may vary.

4. Optical and mechanical properties:
