¹ The optical power can be tuned from virtually 0% to 100% by changing the driving current of the laser diodes. 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.

³ Noise level is measured with a fast photodiode connected to an oscilloscope. The overall system bandwidth is from 2 kHz to 20 MHz.

⁴ Measured at 1 m from output aperture between the centers of two most distant beams.

⁵ Break-out-boxes AM-C8 and AM-C3 can be used for conversion of UART communication to either USB or RS232.

⁶ If the break-out-box AM-C9 is used, a PD (Power Delivery) type of power supply can be used.

⁷ Excluding control interface pins and an output window/fiber assembly.

⁸ For single enabled wavelength.

⁹ Whichever occurs first.

¹⁰ TTL digital modulation up to 10 MHz.

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.
