PL-E series Laser Pointers

PL-E Pro series Lasers’ AC in integration, robust design, dismountable design, internally focusable feature, added safety features, metal button, spare barrel,

long runtime and and high reliability make them a better option for outdoor or field use where a a high power, high stability handheld laser is required.

PLE Pro series lasers are good for lab use where portability and low cost are necessary. PL-E MINI is the mini version of PL-E Pro series.

PL-E series Laser pointers with varying wavelengths have different characteristics and applications. Here is an introduction to laser pointers of these wavelengths:

405nm Laser Pointer: It emits a bluish - violet light. The output power can range from 0.4mW to 600mW, usually with a dot - shaped output, and the laser beam is circular. It uses high - quality industrial laser diodes, featuring excellent beam quality, long service life, low - temperature startup, and high - stability output power. It can be used in industrial laser surveying instruments, precision laser positioning, and other fields.

445nm 450nm Laser Pointer: Usually emits a blue - violet light. It has a relatively high brightness and is often used in laser shows, astronomy pointing, and other applications. High - power 445nm laser pointers can also be used for some burning experiments, but they need to be used with caution due to their high power, which may pose a risk of fire or injury.

515nm 520nm 525nm Laser Pointer: It is a green laser pointer. With a 5mW output power, it can emit the brightest and most visible green light directly from the laser diode, thanks to the advanced green laser diode manufacturing technology. It has the characteristics of continuous optical output, stable performance, and is widely used in metrology, laser shows, and biomedical applications.

532nm Laser Pointer: It is one of the most common green laser pointers. It is usually powered by a rechargeable battery, with a power of 200mW or more. It has the advantages of convenient external focusing, which can adjust the thickness of the light column and the size of the light spot. It is widely used in teaching demonstrations, astronomy pointing, and other aspects.

635nm Laser Pointer: It is a red - light laser pointer, which is often used in teaching presentations and conference instructions. It has a relatively high brightness among red - light laser pointers, and the beam is relatively visible, which can attract the audience's attention.

650nm Laser Pointer: Also a red - light laser pointer, its maximum output power is usually less than 5mW. It is suitable for most presentation or lecture occasions, and can also be used to play with pets indoors, such as cats and dogs.

660nm Laser Pointer: It is a red - light laser with a relatively long wavelength. It has certain applications in medical treatment, such as low - level laser therapy, which can be used for some therapeutic effects on human tissues. It also has some applications in scientific research, such as biological fluorescence excitation experiments.

808nm Laser Pointer: It emits infrared light, which is invisible to the human eye. It is often used as a pump source for other lasers, such as pumping a Nd: YVO₄ crystal in a 532nm green laser pointer to generate 1064nm laser, and then doubling the frequency to 532nm through a KTP crystal. It is also used in some infrared lighting, laser ranging and other fields.

980nm Laser Pointer: It is also an infrared - wavelength laser, mainly used in the field of optical fiber communication, laser pumping, and medical cosmetology. In medical cosmetology, it can be used for some minimally invasive treatment technologies, and in the field of laser pumping, it can be used as a pump source for some high - power lasers.

1064nm Laser Pointer: Even though 1064nm light is invisible, it poses significant risks to eye safety—direct or reflected beams can cause retinal damage. Proper protective gear (infrared-blocking goggles) and adherence to laser safety standards (e.g., Class IV for high-power units) are mandatory.
