Among all visible optical spectrum, red laser diode module with wavelength of 680nm is in the red light region, which has a good excitation effect on some specific fluorescent substances, and good penetration in biological tissues. It is suitable for some deep tissue imaging studies in the biomedical field. In practical precise dot measuring works, it can provide high density red laser light of a single wavelength, which can reduce spectral interference, make experimental results more accurate and clear, and is conducive to the study of the interaction between light of a specific wavelength and matter.
In practical precise dot measuring works, owing to the easy use of an AC/DC adapter, this 680nm red laser diode module is able to work with continuous red laser beam emission from an import 680nm red laser diode within wide range output power of 5mW to 100mW. Configured with a metal heat sink cooling system inside a 16mm or 26mm diameter anodized aluminum alloy housing tube, it enables stable and ultra clear red reference dot projection for a quite long time. In addition, when 680nm red dot laser is used in different working environments, including wide range operating temperature, different humidity, or mechanical moving or calibration, it still maintains ultra clear and no decay light red dot alignment for multiple application fields.
Being made with a qualified glass coated lens in front of beam aperture, this single wavelength 680nm red laser diode module enables high transmittance red laser light emission and ultra clear red dot indication. The strong coherence of the laser enables it to produce stable and obvious interference and diffraction phenomena in interference, diffraction and other experiments, which is convenient for accurate measurement and analysis. Even in experiments of weak signal detection, highly bright red dot laser can provide sufficient light intensity to ensure the observability and accuracy of the experiment.
