What is an efficient job for users to make ultra clear and accurate dot indication in distance? Not able to rely on a simple green laser pointer or prior dot positioning works, it would be a quite nice solution to apply a highly bright beam emitted tool of a 515nm green laser diode module. It applies advanced 515nm green laser diode tech and a qualified glass coated lens inside a durable anodized aluminum alloy housing tube. Whenever it projects highly visible forest green laser beam and green reference dot from beam aperture, not limited by long distance or other complex working environments, this direct diode emission made 515nm green dot laser is used as highly stable optical reference source and precise target excitation/labeling tool, meeting the needs of microscopic observation, dynamic tracking, and experimental calibration in multiple disciplines, including physics, biology, and materials science.

Usually 515nm green laser diode module applies an import 515nm green laser diode as its beam emitting source, which is in need to make long term lasted dot alignment onto different working surfaces. From the very beginning design of this laser device, the primary use of an metal heat sink cooling system and APC, ACC driving circuit board are configured with a durable anodized aluminum alloy housing tube. Whenever it gets superior nice heat dissipation and thermal conductivity, this direct diode emission made 515nm green dot laser alignment assures constant output power and electric current supply, and long time lasted green dot indication within 8 to 10 hours per day.

After quite easy connects with 5V, 9V, 12V 1000mA AC/DC adapter, not any longer spending extra time on battery change, this 515nm green laser diode module projects pure green laser light with excellent monochromaticity and narrow spectral line width, and avoids spectral overlap with commonly used fluorescent dyes in scientific research, such as FITC, with an emission peak around 515nm, thereby preventing interference with observational or experimental data. Being made with an import 515nm green laser diode within 50mW to 200mW, besides its generating of ultra intense and powerful forest green laser light source, 515nm green dot laser alignment also makes highly precise dot indication at different work distances and ambient lighting occasions as well.

After quite easy screw of adjustable focus optic lens design, when 515nm green laser diode module gets immediate forest green laser light source concentration, it converts into increasing accuracy green reference dot projection within the longest distance of 25 meters. After its long term constant dot alignment work, it meets the precise dot positioning requirements of microscopic experiments (such as single-cell observation) and ensures reproducible experimental data. Within wide range operating temperature, 515nm green dot laser alignment allows for tolerance to specialized environments such as laboratory incubators and cryogenic chambers. Select models feature electromagnetic interference (EMI) immunity, making them unaffected by electromagnetic radiation from equipment such as centrifuges and mass spectrometers.

Core applications in scientific research fields:

Biomedical Research: In fluorescence microscopy, low-power green alignment laser dot marks specific regions of cell samples (such as the nucleus and organelles) to assist in locating and exciting fluorescent probes. It can also be used in in vivo imaging experiments of small animals to mark tissue locations to be observed and avoid observational errors caused by sample movement.

Physical Optics Experiments: In light interference and diffraction experiments, 515nm green laser diode module acts as a monochromatic point light source to generate clear interference fringes. In optical system calibration (such as lenses and prisms), it marks the center of the optical path to detect optical path deviation and image quality.

Materials Science Research: In material surface property testing (such as hardness and wear resistance), the green laser dot locates a tiny test area (micrometer-level), allowing precise alignment with the test point when used with a nanoindenter or scanning electron microscope (SEM). It can also be used to test the photoresponse of new optoelectronic materials, serving as an excitation source at a specific wavelength.

Space Physics and Astronomical Observation: In laboratory experiments simulating celestial motion and space particle trajectory, green alignment laser marks the reference coordinates of the observation area, assisting high-speed cameras in capturing particle trajectories. In atmospheric optics research, it can also serve as a target indicator for lidar (LiDAR) to calibrate radar detection angles.
