LET US HELP WITH YOUR SELECTION

A Word about brightness/wavelength selection:

When visible diode modules first came out, they were available in a deep ruby red beam color- 670 nanometers (nm). This is the measure of the color of the beam or wavelength of the laser light. 

As time went on, other wavelengths were produced commercially as research and manufacturing progressed. New wavelengths were 650 nm and 635 nm. To date, the brightest red diode modules are 635 nm. Now with advances in materials, other wavelengths are available, i.e.,  green.

For most applications where a human will be viewing the beam, and the brightest beam is desired, choose 635 nm. The eye is most sensitive in the green area of the color spectrum. That is given the same output power, a green laser beam will appear much brighter than a red one. Any laser module whose color is closer to green will appear brighter, and the 635 & 650 nm are in this category compared with 670 nm. The price is slightly higher for these since the manufacturing is more complex. Note: Many electronic detection systems have sensitivities farther from the green, actually in the near IR. An IR module or a 670 nm wavelength may be best if the beam does not need to be seen by eye.

The 532 nm OEM laser modules are the brightest available. 

The LM, or LQ could be the answer.
• LM: COMPACT SIZE: < 3/8" diameter 
• AVAILABLE WITH CONVENIENT SPRING CONTACT
• LQ: SMALL BEAM DIAMETER WITH COMPACT SIZE

The LB, or LC could be the answer.
• LB: 3 ELEMENT GLASS LENS
• LC: PLASTIC ASPHERIC LENS- OBSOLETE, see LQ as the LQ was the internal component of lC
• READY TO USE BLACK ANODIZED ALUMINUM HOUSING
