A Cost-Efficient Open-Source Laser Engine for Microscopy
Researchers from EBML in Heidelberg and the University of Jena recently published a paper entitled: “A cost-efficient open source laser engine for microscopy”.
The abstract of this paper states: “Scientiﬁc-grade lasers are costly components of modern microscopes. For high-power applications, such as single-molecule localization microscopy, their price can become prohibitive. Here, we present an open-source high-power laser engine that can be built for a fraction of the cost. It uses aﬀordable, yet powerful laser diodes at wavelengths of 405 nm, 488 nm and 640 nm, and optionally a 561 nm diode-pumped solid-state laser. The light is delivered to the microscope via an agitated multimode ﬁber in order to suppress speckles.”
The only DPSS laser used in this setup was the gem 561 with 500 mW output power, produced by Laser Quantum.
