532nm and 650nm laser pointers are popular with business professionals, medical professionals and educators. What are the differences between them and which one is much better? Well come with me on a voyage of discovery… |
Appear The year 1980, a new millennium and also began a new realm of amateur laser enthusiasts. Red laser pointers (wavelength 650nm) were the first handheld lasers to hit the market. They are the simplest pointers, as laser diodes are available in wavelengths.
532nm laser pointer is also call green laser pointer; it is the most common in the market. They are bright and high power, have caught people's fascination ever since they were introduced to the public.
Green laser pointers appeared on the market circa 2000, but occupy most of the market quickly.
Features Wavelength determines the color, beam visibility of laser pointer. 532nm green laser is the most common type of DPSS laser. It is generated in an indirect process, beginning with a high power infrared AlGaAs laser diode operating at 808nm.
Green laser pointers are 5 to 20 times brighter than traditional red ones, so visibility is much better on projection screens, HDTVs, etc. The reason Green Lasers seem more powerful is because the human eye is especially sensitive to the green light they emit.
650nm red laser is made up of 650nm red laser diode. It is a technology matured laser, and featured by perfect collimation and stable performance. Usually, 650nm red dot generating laser alignment system is able to make the best alignment performance in high light operation environment.
Price The 650nm laser pointer is much cheaper than 532nm, but as new technology developed it was possible to mass produce green laser pointers. The price of green laser pointer will be cheaper.
532nm and 650nm laser pointers can be use as presentation, when you bring them home; the first thing you'll realize is that you'll be able to see the beam at night! Are you prepared for the ultimate light experience!
532nm green laser pointers are more popular than 650nm red one. If you have enough budgets, it will be a great choice to get the multi-color one.
