Description

The compact 532 nm module is a DPSS laser featuring high output power, very good beam quality, and superior long-term power stability. The lower-coherence version features several longitudinal modes at higher power and typically single-longitudinal mode at a power level of ~10 mW. 532 nm wavelength radiation is commonly used in fluorescence excitation, scanning microscopy, and general green light illumination. The free-space version features a small beam diameter and a very small form factor.

¹ The optical power can be tuned from virtually 0% to 100%. However, other specifications, such as central wavelength, power stability, noise, polarization ratio, beam shape, quality and circularity are not guaranteed at power levels other than factory preset power. Significantly worse power stability is to be expected at very low power levels, e.g. <3% from specified nominal power.

² The long term power test is carried out at constant laser body temperature (+/-0.1 ‎°C) using an optical power meter with an input bandwidth of 10 Hz. The actual measurement rate has a period of about 20 seconds to 1 minute.

⁴ Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.

⁵ Beam width and height are measured at 0.4 m from output aperture.

⁶ For lasers without integrated optical isolators.

⁷ Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.

⁸ Excluding control interface pins and an output window/fiber assembly.

⁹ Whichever occurs first. The laser has an integrated operational hours counter.

Confocal Microscopy

Confocal microscopy is a powerful imaging technique used in biological and materials science research. By employing point illumination and a spatial pinhole, confocal microscopy eliminates out-of-focus light, resulting in sharper, high-resolution images. This method enables three-dimensional imaging of specimens with exceptional optical sectioning, making it valuable for studying biological structures and dynamic processes at the cellular and subcellular levels.

Food sorting

None

Flow Cytometry

Flow cytometry is a sophisticated analytical technique widely used in biomedical research and clinical diagnostics. It allows for the simultaneous analysis of multiple physical and chemical characteristics of cells or particles as they flow through a laser beam. By utilizing fluorescence and light-scattering principles, flow cytometry provides valuable insights into cell populations, allowing researchers to study cell morphology, identify cell types, and assess various cellular functions with high-throughput precision.
