Green laser diodes are a quite new products compared to the previous technology of the DPSS green laser.

The wavelengths proposed are comprised between 510nm to 530nm (most common : 515nm green laser and 520nm green laser)

The green laser diode modules show better stability and a wider operating temperature range. Relying on the high performance of the green laser diode, it usually used for higher visibility requirements like outdoor applications, law enforcement, image and laser patterns projection, or heavy industry applications.

The NIR (Near IR) range Egismos can offer is from 780nm to 1064nm. The infrared laser applications depend on each different wavelength feature. Infrared is popular for use in laser sensing or laser detection (robot navigation, obstacle detection, security sensors). Some industrial and law enforcement applications for night vision also use IR lasers as well. Egismos can customize the laser modules as per your requirements and/or design specific DOE (Diffractive Optical Element) that will project custom laser patterns for your application.

Customized Laser Module

EGISMOS provides standard laser modules that are convenient for quick and easy orders of samples or small quantities on our Online-store.

We also provide and welcome orders of custom made laser modules with any specification requirement.EGISMOS is not only a laser module manufacturer but can also provide optics, optoelectronic integrated solutions from design to production.
If you can not find the laser module that fits your application, please email your inquiries to sales@egismos.com and briefly describe your requirements or applications to us. We will reply to you in a very short time (usually within two working days).

Any part or specification of each module can be modified.
Below is an introduction of some of the specifications for the laser modules that we would need to know to be able to propose to you the best adapted solution. You can also describe the application and the work environment of the laser you desire, and our laser design team will let you know our suggestions and all possible solutions, from the most cost efficient to the highest quality laser modules.

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
(Please refer to our laser diodes product list at http://www.egismos.com/laser-diode.html)
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).p>

※  According to their different specifications, the cost of a laser diode can vary a lot from one to another.
If your application can support some flexibility, please let us know your acceptable margin range. In this way we will be able to propose different choices and the most cost efficient solutions. 

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).

You can check some of our available specific DOE laser patterns at our dedicated page for DOE: http://www.egismos.com/optical-components.html

※  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. EGISMOS can calculate these parameters for you and let you know the possible outcome for your further evaluation.

※ EGISMOS has the optical design capacity to design and create new optical components such as Laser Collimating Lens, Diffractive Optical Elements, etc.. according to your requirements. If you had any questions, please don't hesitate to let us know.

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.

Apart from CW mode (continuous wave mode), our laser modules can be designed to input a TTL modulation if needed. It can be fixed to run at a certain frequency (Hz) or a specific duty cycle, or can it be alternated via an external PWM input. For such functions, please provide us your electronic requirements.

-Main characteristics of laser driver circuit: operating voltage range, CW or Pulse modulation mode (TTL/PWM signal control: frequency range), driving current requirements, APC or ACC mode, laser module safety or circuit protection requirements.

※ Our laser modules can also be prepared to meet eye safety requirements of international standards (CE, FDA, JQA , ...).

4. Optical and mechanical properties:
The laser modules dimensions (diameter and/or length of laser module casing) can be modified according to your needs, and technical drawing can be provided for evaluation.
The laser module casings can be designed into many shapes and with different materials, their surfaces can be treated for different operating environments like IP, anodization for electrical isolation etc. Some differences in a laser module casing design might help to reach different operating temperatures  so as to offer the best protection for the inner components.

-Main characteristics for mechanical requirements: dimension requirements, boresight or called coaxial angel accuracy of laser module.

※ Other options, such as laser boresight or coaxial requirements, can be additionally specified (our standard specification are <2°).

Eye Safety

From the first lasers in 1964, it was clear that this light source had a power not only to do the required job, but that could also be very dangerous if operated improperly. Laser safety guidelines were written for consumers, and power levels are usually written for visible-light, continuous-wave lasers. Laser are now divided into Class 1, Class 1M, Class 2, Class 2M, Class 3R, Class 3B, Class 4. For pulsed lasers and invisible wavelengths, other power limits may apply. In the USA it is considered that Class 2 lasers are safe for consumers, while the EU requires lasers to be Class 1 for consumers products. It is suggested to people working with class 3B and class 4 lasers to protect their eyes with safety goggles, which are designed to absorb light of a particular wavelength.

The main characteristics and requirements for the classification system as specified by the IEC 60825-1 standard are listed, along with typical required warning labels. Additionally, classes 2 and higher must have the triangular warning label shown here and other labels are required in specific cases indicating laser emission, laser apertures, skin hazards, and invisible wavelengths.

Warning label for class 2 and higher

As the professional laser module manufacturer, EGISMOS standard laser modules all can fit the eye safety requirements and support the customer to apply the certification of your laser products.
