The Green Laser Pointer has brightest beam out of the laser colors per milliwatt. The green laser is the number one choice for astronomy enthusiasts since the beam can be seen at night and used to point directly at a star. Great for presentations, camping, signaling, military, construction, etc.

This Green Line Laser Pointer has two functions in one. With the filter one it creates a long straight line that you can use to align things; just like a professional. Easy to use, the filter twists back and forth to move the line allowing you to easily find the perfect alignment.

The Red Laser Pointer has been around the longest and was developed in the 1980's and originally cost hundreds of dollars. Now the classic laser pointer offers a great choice for presentations or for playing with pets. The dot emited is not as bright or hard on the eyes as a green laser dot can be.

The Blue/Purple Laser Pointer is the newest laser and was introduced in the 2006. This laser reacts with ultraviolet materials to produce a glow, just like that experienced from black lights. Unimaginable fun can be had with a UV laser; you can write on any glow-in-the-dark surface and it instantly charges.

The Laser Pointer Collection offers each one of the laser colours at a discounted price. Included in the collection is the Green Laser Pointer, Red Laser Pointer, and the UV Laser Pointer. One laser may not be enough for your needs. You may want a red laser as a safe toy for your pets, a UV laser for glow in the dark experiments and a green laser is great for star gazing at night.
