Necsel NovaTru™ Chroma 780
Wavelength Stabilized Laser
Wavelength Stabilized
- 20-50 mW
These stabilized lasers combine high performance fiber optic packaging and compact laser drive circuit design for rapid integration into flow cytometers, interferometers, spectral instruments or laboratory research setups where reliable, stable single-mode laser performance is required. The integrated driver circuitry is versatile enough for many other potential sources as well.
