The NovaTru Chroma range is an example of a wavelength stabilised source, which utilises a high performance Volume Bragg Grating to enable excellent wavelength stability (± 0.5nm), which is virtually temperature independent (typically 0.01nm/°C).
The NovaTru Chroma 633 SLM is the perfect drop-in replacement for HeNe lasers, offering up to 50mW of stable power at 632.8nm.
A variety of other wavelengths are available making these compact module sources ideal for applications such as Raman spectroscopy, flow cytometry, semiconductor processing, fluorescence excitation and more.
Various fibre coupled and free space output options are available, as are collimated lenses, which can supply TEM00 Gaussian beam profile if desired. The operating voltage is only 5V and a modulation of up to 100kHz can be achieved.
