This is a super white light flashlight, but the laser flashlight is more powerful than this. In fact, the official name of the laser flashlight is the laser pointer. That is to say, the laser flashlight is named because it looks like a flashlight. It is actually a kind of laser pointer. It has a similar function as a laser pointer and a star pen, but it is generally larger and usually has a higher power. The official name of the laser flashlight is "laser pointer", which is different from the general laser pointer and pointer pen because of its shell. Laser flashlights are similar to ordinary flashlights, they are larger and usually have a higher power. It is a pen-shaped transmitter designed to make the visible laser portable, easy to hold, and processed by a laser module (diode). Common laser pointers include red light (650-660nm), green light (532nm), blue light (445-450nm), and blue-violet light (405nm).
The laser flashlight is a semiconductor laser. It differs from the laser pointer in that its volume is easier to dissipate heat. The laser module directly contacts the aluminum flashlight casing. The general flashlight module is relatively thick, so the stability is superior to the laser pointer (laser The pen is a copper shell)! The power of laser flashlight generally ranges from more than 5mw to several hundred milliwatts, and some laser flashlights (such as blue laser flashlights) have a power of up to 1w; at the same time, some laser flashlights also have an adjustable focus function, the laser beam is strong and clear, and the range is far, most All use rechargeable lithium batteries (such as 18650 type rechargeable batteries), and some have a safety lock, which is named like a flashlight. Early laser flashlights used helium-neon (HeNe) gas lasers with a wavelength of 633 nanometers (nm), and were generally used to produce energy not exceeding 1 milliwatt. The cheapest laser flashlight uses a deep red laser diode with a wavelength close to 670/650nm. The more expensive ones use 635nm red-orange diodes. This wavelength is easier for human eyes to recognize. Laser pointers also have laser flashlights of other colors. The most common is a green light with a wavelength of 532nm.
The laser pointer needs to be warmed up in winter. Some laser pointers need to warm up for 2-3 seconds even in summer. Since the laser pointer depends to a large extent on the working temperature, it will affect the lighting and continuous lighting in high-temperature and low-temperature atmospheres. this is normal phenomenon. For example, if it is very cold in winter and the laser pointer is not fully activated, it will light up when held in your hand. Even with a bright projector or large LCD image, you can clearly see the light, providing a more comfortable presentation. With a powerful laser pointer, you can see it even in a bright room or during the day.
