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.

3 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 Can be supplied upon request.

6 Other core diameters to be discussed.

7 Output power is heavily dependent on fiber insertion repeatability.

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

9 APC - Automatic Power Control.

10 TTL digital modulation up to 10 MHz in automatic current control (ACC) mode. TTL modulation speed in automatic power control (APC) is up to 1 kHz.

11 This function can be enabled in hardware only if the fast modulation option is disabled. The customer must specify this before ordering the laser.

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

13 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.

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.
