Among lasers, optical lenses play an important role. The excitation conditions of the laser are very simple. There are working materials, excitation energy, and resonant cavity to generate laser. However, the utilization and utilization rate of the laser at this time are very low. It needs to be processed by an optical mirror group to reach [...]
Laser diode is a kind of light source semiconductor laser invented in the 1960s, also known as laser tube (Laser Diode)。LASER is an abbreviation of "Light Amplification by Stimulated Emission of Radiation", usually abbreviated as LD.Since it can produce light with exactly the same properties such as wavelength and phase, high coherence is its biggest feature 。Laser diodes [...]

Laserland provides 980nm laser diode module for our clients. 980nm ir laser module is an ideal laser for shooting video game. The gun let out the invisible ir laser signal and the terminator receives the the invisible laser signal. The longer distance demands higher laser power. Normally 30mW and below can work fine in the distance [...]
Red positing laser is a cheaper and commonly used option than CNC machines. CNC machines including laser engraving machine(engraver), often has a wavelength of 1064nm, 10600nm CO2 which is not visible to human eyes. We need red laser indicators like 650nm red laser to indicated the laser movements of the machines. Red Positioning Lasers for positioning [...]
Lumber Cutting, sawmill workshop, woodworking all need laser as their guide. Line laser modules like Laserland produces, make clear visual lines for woodworking industry and increase productivity. Laser line generator modules are a must tool for tumber, log, lumber cutting and processing. Laser line generators are widely used for decades in wood machinary industries for brige [...]

What is Machine Vision? Machine Vision or Visual inspection is to use a machine to replace the human eye for measurement and judgment. Visual inspection refers to the conversion of the captured object into an image signal by machine vision products (that is, image pickup devices, divided into CMOS and CCD), which is sent to a [...]
Applications of Infrared Up-conversion Materials in Anti-counterfeiting and Trace Indentifying Technology Key words: infrared up-conversion; changing infrared to visible light; anti-counterfeiting technology. 1. Principle The general light excitation process follows the Stoke-Lomoli rule, that is, the maximum wavelength of the emitted spectrum of the excited substance moves in the long-wave direction relative to the maximum wavelength [...]
Laserland can make diffraction gratings or DOE(Diffractive Optical Elements) for laser pattern projection according to your design. The grating is widely used in laser projection, such as laser module, laser stage light grating, laser pen, laser level (grating line, cross line), laser cutting machine, laser scanner, laser flashlight, camera focused grating. The pattern can also be [...]
