لیزر ابزاری است که نور را به صورت پرتوهای موازی بسیار باریکی که طول موج مشخصی دارند ساطع میکنند. این دستگاه از مادهای جمعکننده یا فعال کننده نور تشکیل شده که درون محفظه تشدید نور قرار دارد. این ماده پرتو نور را که به وسیله یک منبع انرژی بیرونی (از نوع الکتریسیته یا نور) به وجود آمده، تقویت میکند.
لیزر نقطه ای دارای لنز خطی است که امکان فوکوس کردن را دارا می باشد. این ماژول با طول موج 650 نانو متر و ولتاژ کاری 3.3 تا 5 ولت قابلیت تنظیم نور را دارد. جریان این ماژول کمتر از 300 میلی آمپر است و مشحصه ظاهری آن از نوع TO-18 می باشد.
Description:
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation."
Red Dot 250mW Laser Diode Module [650nm] is a 250mW powerful laser set, which is based on a 250mw laser diode with the red beam at 650nm wavelength in a small aluminum housing associated with an optical lens, and an internal circuit driving and controlling. This laser set can be supplied with 3.5V up to 5V DC.
A laser diode, (LD), an injection laser diode (ILD), or diode laser is an especial semiconductor P-N junction, to emit coherent light with a narrow spectrum. Two big challenges of laser diodes projects are proper heat control (heat dissipation) and proper powering supply (diode driving). Therefore, the laser diode should be attached to the heat conductive case (copper, aluminum, and so on) to export diode heat-producing into this body. Also, an optical lens is placed on the body to focus the laser beam.
High-power laser diodes are used in industrial works such as heat treating, cladding, seam welding, and for pumping other lasers, such as diode-pumped solid-state lasers. This laser tool can be used in pointing, metrology, engraving (on bamboo, wood chips, mobile phone shell plastic, leather), demonstration laser source, laser locator product, test instrument, laser medical device, laser leveling instrument, barcode scanner, power tool.
