Some Keys Problems of Laser Pointers

What is price difference of laser pointers?

Laser pointers with different output power and wavelength produce different production cost and different technical requirement. For instance, green laser and red laser up 200mw get the same price ranges. Red laser higher than 300mw gets even higher price.

Blue laser, especially high output power, has lower requirement of raw material cost and technical requirement. It is always available with much lower price.

How to wear laser safety goggles properly?

Laser hazard exits on each time of operation of laser pointers. If only outward irradiation spot at long distance, no need of wearing laser safety goggles. Long distance laser irradiation, laser light is not scattered or reflected onto the eyes.

Only close distance laser pointer pointing, laser light causes reflection, scattering, diffusion. Part of laser light will shine on the eyes. Long term watching will feel vertigo and tired. A pair of laser safety goggles is need in such occasion.

When laser pointer beam is visible?

If selecting output power is very low, laser beam is not visible both at night and during daytime. The beam of 532nm green laser pointer up 30mw is clearly visible at night. Green laser beam is even visible in room during daytime. Higher output powered laser pointer gets even stronger and more intense green laser pointer beam.

Which output power laser pointer can be used as burning laser?

Higher powered laser pointers always gets even stronger burning ability. Laser pointer up 100mw can burn match easily. 200mw laser pointer can burn cigar, cut tape, pop balloons.

What is the difference from red laser and green laser?

Red laser gets wavelength of 635nm and 650nm, and green laser gets wavelength of 515nm, 520nm and 532nm. Different wavelength laser gets different color laser beam and light spot in operation.The burning ability of red laser of certain output power is better than green laser.

The different laser nature specialty causes red laser beam visibility much weaker than green laser with same power. Green laser gets even brighter and more visible green laser beam radiation.Users cannot make decision on quality of laser pointers, only if the exact requirement and personal preference.

What is the difference between laser pointer and handheld laser?

1. Low powered laser pointers selects pen style design, and high powered laser selects handheld flashlight design in order to get larger space reserved for its larger laser module. High power handheld laser needs larger space as its thermal stabilization system. Handheld laser always adds functions of adjustable focus and safety key protection device.

2. Different operating time. Laser pointer can maximum light up no more than 15 seconds, and then 10 seconds cooling down. Handheld laser suggests continuous light up no more than 3 minutes.

3. Handheld laser with focus adjustable design can fully even more practical use for clients.

What are the key points of blue lasers?

Blue laser with charming and attractive sapphire blue laser beam, is very popular among laser amateurs and professionals. Laser enthusiasts even using high powered blue laser for various burning experiments. When users are operating high powered blue lasers, users should pay attention to:

1. Long term continuous burning can cause extremely heating, thus affect serving lifetime of laser tube and then burn out. The suggested pointing time is 30 seconds and cooling down.

2. Proper installation of battery positive and negative of blue laser pointer

3. Cautious with dust, not use blue laser in smoke, water vapor environment

4. Close distance blue laser pointing on objects, users should pay attention to laser diffuse, reflection and refraction light, and prevent eye damage.

5. Safety operation of blue laser should not irradiate combustible substances, human and animals.

6. Remove battery when blue laser is not in use, just put it into the right place.
