Kokuyo Co Ltd has released a laser pointer that can be continuously used for about 60 hours with two AAA alkaline batteries.
The laser pointer for PCs (pen type) is expected to be used in large spaces such as seminar sites. Its price is ¥40,000.
The product uses a green laser light with a wavelength of 515nm so that the light can be easily seen from a distance. This time, Kokuyo used pulse waves instead of continuous waves, which is used for the company's previous product. As a result, the laser pointer can be continuously used for about 60 hours, which is about 10 times longer than in the case of the previous product.
When an accompanying receiver is connected to a USB port of a personal computer, it becomes possible to use the pointer for turning a page of presentation software such as Microsoft Corp's PowerPoint. The pointer has a function to notify the user of a low remaining battery level by using an LED lamp.
The diameter, length and weight of the laser pointer are 14.6mm, 169mm and 80g, respectively.
