Single-mode fiber-coupled 405 nm laser diode in the compact and robust MatchBox platform. Proprietary fiber coupling technology offers alignment-free operation throughout the lifetime of the laser. Single-mode fiber ensures ideal beam quality and focusability, thus making this laser the best choice for high-resolution fluorescence imaging or 3D lithography applications. Proprietary fiber coupling technology ensures good power stability and excellent fiber-coupling efficiency.
A core-less end-cap is included for fiber tip protection against optical damage and degradation due to optical radiation.

By default, this type of laser is built with FC/PC connector, but other fiber terminations are available upon request. Details about non-standard connector and the fiber used with it should be discussed with the Integrated Optics sales team.

Fiber Termination - FC/PC (PT): FC/PC has good insertion repeatability, therefore is often used in single-mode fiber applications. Features a key for polarization-maintaining fiber installations.

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

6 APC - Automatic Power Control.

7 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.

8 This function can be enabled in hardware only if the fast TTL modulation option is disabled. The customer must specify whether the fan control or TTL modulation is required before ordering the laser.

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

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.
