Description

405 nm diode lasers are popular in a variety of fluorescence applications. Many organic materials have strong fluorescence at this excitation wavelength. Other applications include UV curing and inspection. 405 nm radiation became particularly popular due to the fact these diodes are used in Blu-ray optical disc equipment thus, they are inexpensive.
Integrated precision driver electronics ensures low-noise and very stable operation throughout the wide temperature range. Internal voltage conversion allows using a 5V power supply while maintaining low noise operation.

Isolator - No Isolator (NI): No isolator integrated.

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 APC - Automatic Power Control.

⁹ 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.

¹⁰ 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.

¹¹ Excluding control interface pins and an output window/fiber assembly.

¹² 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.
